Physical Characteristics The adult mouse is about 2 1/2" 3 3/4" (head and body) and a tail length of 2 3/4" long. Gray with either light gray or cream under belly. Behavior Mice are found where food and shelter is plentiful and prefer nesting sites that are dark and in secluded places with an abundance of nesting materials, which include; paper products, cotton, packing materials, insulation, fabrics and etc. Behavior Mice are found where food and shelter is plentiful and prefer nesting sites that are dark and in secluded places with an abundance of nesting materials, which include; paper products, cotton, packing materials, insulation, fabrics and etc. Mice are territorial and will show aggression to unrelated males and females outside of their social structure. During daily territory patrols mice will investigate and explore anything new or changed and establish new travel routes as necessary. Territories vary in size but it is usually relatively small. Mice may access through openings greater than 1/4, allowing mice many points of entry. Mice feed typically on anything but prefer seeds and insects, when feeding on high protein food mice require water but prefer sweetened liquids. Disease Carriers Mice may carry or contribute to the following: Salmonella Plague and typhus Tapeworms Rickettsial pox Jaundice/leptospirosis/Weils disease Liponyssoides sanguineus (Hirst) Favus Poliomyelitis Treatment Good sanitation is essential for effective long term control. Mice can enter any opening larger than 1/4 inch, making it virtually impossible to completely mouse-proof a building. The trained Clark technician will determine the best means of control for each customer.
Physical Characteristics The adult Norway rat is about 7"- 9 1/2" with a tail length of 6"-18" long. Fur is coarse, shaggy and color is usually brown with scattered black hairs with underside gray to yellowish white. The Norway rat has a blunt muzzle, small ears and eyes. Behavior Norway rats are well know for damaging and destroying material by gnawing, eats and contaminates stored food, its bite is also a risk to humans as they are a vector or carrier of diseases The Norway rat is nocturnal and unlike mice they shy away from new objects introduced into their territory. The Norway rats nesting preference is the lower parts of structures such as basements in piles of debris and or merchandise but has also been found outdoors on or around riverbanks, railroad embankments, piles of rubbish and under concrete slabs. The Norway rat is an opportunistic feeder and although they will feed on anything they do prefer meat, fish and cereal. Disease Carriers Norway Rats may carry or contribute to the following: Salmonella Cowpox Virus Jaundice/leptospirosis/Weils disease Trichinosis Plague Treatment The control of rodents can be widely varied, depending on the individual situation. Covering holes, filling cracks, baiting or trapping may be necessary. The trained Clark Technician will determine the best means of control for each customer.
Physical Characteristics The adult Roof rat is about 6"-8" with a tail length of 7"-10" long. Fur is soft and color is usually brown with black intermixed, to gray to black above with underside white, gray or black. The roof rat has a pointed muzzle, large ears and eyes. Behavior Roof rats are well know for damaging and destroying material by gnawing, eats and contaminates stored food, its bite is also a risk to humans as they are a vector or carrier of diseases. The Roof rat is nocturnal and unlike mice they shy away from new objects introduced into their territory. The Roof rats nesting preference is the upper parts of structures but has also been found in basements as well as outdoors in trees. Once the Roof rat has established a harborage, they tend to follow the same route to their food and or water source keeping their paths clear of debris. Roof rats will feed on practically anything, but prefer seeds, nuts, fruits and berries when in season. Roof rats, if available, will feed on snails, slugs, and the American brown and Smokey brown cockroach. Near waterways the Roof rat feeds on fish, shell fish and other aquatics. Disease Carriers Norway Rats may carry or contribute to the following: Salmonella Plague Jaundice/leptospirosis/Weils disease Trichinosis Treatment The control of rodents can be widely varied, depending on the individual situation. Covering holes, filling cracks, baiting or trapping may be necessary. The trained Clark Technician will determine the best means of control for each customer.
Physical Characteristics The Drywood termite swarmer is up to 7/16" 1/2" long including wings. The head and pronotum orange brown, abdomen dark brown and wings have a smokey tinge. The Drywood termite soldier is up to 5/16" or 5/8"-1/2" reddish brown in color with mandibles, the number of teeth on the mandibles are an uneven amount. Behavior The Drywood termite will colonize in attics where temperatures may exceed 131 F. Here they locate their colonies in wood with more favorable temperatures, such as celling joists that have their bottom sides cooled by the A/C below. Signs of Infestation Drywood termites eat across the natural grain, eating both spring and summer wood. The Drywood termite will make chambers connected by tunnels whose walls are smooth as if finely sanded. When conditions are dry, the Drywood termite will accumulate at the bottom of each chamber with their own fecal pellets to seal it off. Treatment Drywood termites are usually controlled by whole house fumigation or localized treatment.
Physical Characteristics The Dampwood termite swarmer is up to 3/4" - 1" long including wings. The swarmer is light to dark brown in color with a yellow to reddish ting with dark brown wings. Behavior As their name implies, dampwood termites locate their colonies in damp, decaying wood, typically found in old trees, stumps and logs and known for attacking utility polls, pilings and fence posts. Signs of Infestation Dampwood termites eat across the natural grain, eating both spring and summer wood. The Dampwood termite will make chambers connected by tunnels whose walls are smooth as if finely sanded. When conditions are dry, the Dampwood termite will accumulate at the bottom of each chamber with their own fecal pellets to seal it off. Treatment Soil treatment with long residual insecticides to provide a chemical barrier is the most commonly used control or prevention method for dampwood termites.
Physical Characteristics The Subterranean termite swarmer is about 3/8" long including wings. The body is dark brown to black in color. The Subterranean termite soldier is about 3/8" long with mandibles, the mandibles lack teeth. Behavior The Subterranean termite swarms during daylight and occurs during springtime. Colonies are located underground, usually below the frost line and above the water table and rock formations. The Subterranean termite builds mud tubes to travel through areas of adverse conditions and will run from the colony and the food source. Treatment Soil treatment with long residual insecticides to provide a chemical barrier is the most commonly used control or prevention method for subterranean termites.
Physical Characteristics Cellar spiders have extremely long, skinny legs with small bodies that are usually tan or gray. The web of a cellar spider is usually very messy, similar to the web of a cobweb spider. Like all spiders, cellar spiders have 8 legs, 2 body parts, and fang-like mouthparts. The body length of adult cellar spiders about 1/4" or less. Behavior Cellar spiders are usually found in dark corners of cellars, crawl spaces, and garages. They are very long-legged and often confused with daddy-long-legs. However, they are true spiders that spin untidy webs which are often quite extensive. When disturbed, they characteristically bounce in the web. Treatment Cellar spiders can be controlled; Clark Pest Control offers a wide variety of solutions for your home, school and/or business and can address the problems you are having. One of our "Pest-Away" services will certainly take care of the problem for you
Physical Characteristics The adult female is about 1/2" including an almost spherical abdomen about 1/4"-3/8" in diameter with overall length including legs of about 1 1/2"-1 3/8". Females are black in color with identifiable marking of a red hourglass. Behavior Black Widow\'s can be found in irregular webs and hang upside down or in sheltered places, such as; under stones, firewood piles, under decking, hollow tree stumps, trees and rodent burrows. A favorite place is in barns, outhouses, henhouses, sheds, meter boxes, bricks, barrels and woodpiles. Treatment Part of the Clark Pest Control\'s Pest-Away treatment is not only providing a residual barrier for the control of insects and spiders, but to physically sweep down all accessible spider webs.
Physical characteristics: Like the black widow (Latrodectus hesperus, L. mactans), the body of the female adult brown widow spider also known as the gray widow spider and geometric button spider is about 1/2 inch long, with long, banded (tiger-striped) legs, and a geometric pattern on its back. Females typically are light to medium brown in color, although they may range from almost white to gray to almost black, with an identifiable marking of an orange or yellowish hourglass. Males are about half that size, with longer legs than L. Hesperus males. Egg sacs are easily identifiable tan, spherical, with spiky protrusions, not unlike World War II sea mines. Behavior: L. geometricus is a recent transplant from southern Africa; it's a tropical spider that has spread throughout the American southeast, specifically the Gulf Coast. So far in California, it's been found from San Diego County in the south to Los Angeles County in the north, and as far east as Riverside County. Of all the Latrodectus species, brown widows are the most prolific breeders; one female can bear 5,000 young spiders per season. Brown widow spiders weave messy webs that can be found in lots of places around buildings and gardens. Favorite harborages include plastic lawn chairs, plastic flower pots and bird-of-paradise plant leaves anywhere sheltered that offers hiding. It's the females that bite, but brown widows reportedly are far more timid than their black widow cousins. Bites are rarely fatal. If you are bitten, call a physician or visit an emergency room right away. Treatment: The best way to be rid of brown widow spiders is to keep your environment free of them, by removing their webbing and any spiky egg sacs you find. Should you choose to do the job, be sure to wear gloves and a long-sleeved shirt (and long pants and shoes) when moving stored firewood, boxes and lumber. Exclude the spiders from coming indoors by installing tight-fitting screens on doors and windows, and caulk any cracks or crevices they might use to enter. Remove any clutter, indoors and outdoors, that might provide harborage for these spiders, like old boxes, clothing and lumber, and don't store firewood stacked against your house. Your Clark Pest Control technician will physically sweep down all accessible spider webs as part of the service he provides, and can advise on and implement any additional control methods.
Over the years, the group of spiders to which the brown recluse belongs has been known by various colloquial names: "violin" spiders, "fiddleback" spiders, "recluse" spiders, and "brown" spiders. Many publications refer to the violin marking on the top surface of the head region as the most important diagnostic feature. Although this marking is fairly consistent in mature brown recluses, it can vary in intensity and sometimes fades in preservative, and it is very faint to nonexistent in several recluse species. To be identified as a recluse spider, it must have all five of these characteristics. six eyes in pairs as opposed to eight eyes (like most spiders) uniformly colored abdomen with fine hairs no spines on the legs uniformly colored legs body not more than 3/8" in length The brown recluse is an enigma in California: there are no populations of the brown recluse, Loxosceles reclusa, in the state and fewer than 20 verified specimens have been collected over several decades in California. Behavior Recluse spiders, as their name implies, are reclusive. These nocturnal spiders emerge from their retreats at night and actively hunt down prey or may wait for prey to land in the small area several inches from their retreat. Although they do not build webs to capture prey, they do use silk to build a retreat in which they hide during the day. As dawn approaches, they may seek shelter in dark places such as in clothing or shoes. In nature, recluses are found in cracks and crevices in and under rocks. Recluses have very much benefited from human-altered environments where they are readily found under trash cans, plywood, tarps, or rubber tires, in boxes, etc.
Physical Characteristics The most common fly is the house fly. It is black and about 1/4" inch long. The sex of a house fly can be determined by the distance between their eyes (females are wider). Also, the female is usually larger than the male. Behavior Flies have been known to migrate up to 20 miles, although, typically they will stay within 1-2 miles from their release point or larval habitat. Flies are attracted to building or dwellings via air currents and odors with their preferred temperature being 83 degrees, on cooler days flies are usually found around doors and windows of dwellings. During the day, flies will fly or rest less than 5 feet above ground, where at night tend to fly and rest above 5 feet. Flies have been known to harbor over 100 different diseases ranging from typhoid fever to salmonellosis. Treatment Most infestations of flies can be controlled with Clark\'s Year Round Pest Control in conjunction with the treatment of any pests.
Physical Characteristics The adult Field cricket vary in size from 1/2" 1 1/8" long. They are typically black but varies from brownish yellow or straw in color. Behavior The Field cricket is mostly known for severely damaging and destroying field crops and vegetable crops. Field crickets can be found outdoors in moist situations such as; mulched areas, unweeded plant beds, in and around woodpiles, stones, debris and etc. Their presence is often indicated by the males chirping sound which occurs either day or night and is known as a calling song used to attract females. Treatment Most infestations of crickets can be controlled with Clark\'s Year Round Pest Control.
Physical Characteristics The adult House cricket is 3/4" 7/8" long. They are typically light yellowish brown with 3 dark crossbands on the head. Behavior The House crickets name comes from the fact that this cricket often enters homes where they can survive indefinitely, hence the House cricket. The house cricket feeds on wool, cotton and synthetics, resulting in large areas of fabric being eaten. The House cricket typically lives outdoors during warm weather, when cold weather is approaching they seek refuge inside homes and sheds. Their presence is often indicated by the males chirping sound which occurs either day or night and is known as a calling song used to attract females. Treatment Most infestations of crickets can be controlled with Clark\'s Year Round Pest Control.
Physical Characteristics The adult Camel cricket is 1/2" 1 1/4" long and have an arched back. They are typically light to dark brown in color. Behavior The Camel crickets name comes from their humped back, similar to a camel. The Camel cricket can be found outdoors in cool moist situations such as under mulch, stones, railroad ties, woodpiles and debris. Around the home they can be found in wells, pipe, under A/C units, concrete pads, sheds, basements, utility rooms, crawl spaces, garages and attics often invading the home in hot and dry weather. Indoors, the Camel cricket has been known to damage and or destroy fabrics. Treatment Most infestations of crickets can be controlled with Clark\'s Year Round Pest Control.
Physical Characteristics Aphids may be green, yellow, brown, red, or black depending on the species and the plants they feed on. A few species appear waxy or woolly. All are small, pear-shaped insects with long legs and antennae. When the weather is warm, many species of aphids can develop from newborn nymph to reproducing adult in 7 to 8 days. Because each adult aphid can produce up to 80 offspring in a matter of a week, aphid populations can increase with great speed. Behavior Aphids are small, soft-bodied insects with long, slender mouth parts that they use to pierce stems, leaves, and other tender plant parts and suck out plant fluids. Almost every plant has one or more aphid species that occasionally feeds on it. Large populations of aphids cause curling, yellowing, and distortion of leaves and stunting of shoots; aphids can also cause a plant to produce large quantities of a sticky substance known as honeydew, which often turns black with the growth of a sooty mold fungus. Some aphid species inject a toxin into plants, which further distorts growth. Ants are often associated with aphid populations, especially on trees and shrubs, and often are a tip-off that an aphid infestation is present. If you see large numbers of ants climbing up your tree trunks, check for aphids (or other honeydew-producing insects) on limbs and leaves above. To protect their food source, ants ward off many predators and parasites of aphids. Management of ants is a key component of aphid management. Treatment Aphids can be controlled through a variety of means including cultural, biological, and chemical means. Clark Pest Control offers a variety of solutions for your lawn and garden and can address problems you are having with both aphids and ants in your yard.
Physical Characteristics Whiteflies usually occur in groups on the undersides of leaves. They derive their name from the mealy, white wax covering the adult's wings and body. Adults are tiny insects with yellowish bodies and whitish wings. Behavior Whiteflies are tiny, sap-sucking insects that are frequently abundant in vegetable and ornamental plantings. They excrete sticky honeydew and cause yellowing or death of leaves. Whiteflies develop rapidly in warm weather, and populations can build up quickly in situations where natural enemies are destroyed and weather is favorable. Most whiteflies have a wide host range that includes many weeds and crops. In many parts of California, they breed all year, moving from one host to another as plants are harvested or dry up. Like aphids, whiteflies excrete honeydew, so leaves may be sticky or covered with black sooty mold. The honeydew attracts ants, which interfere with the activities of natural enemies that may control whiteflies and other pests. Management is difficult. Treatment Whiteflies can be controlled through a variety of means including biological and chemical means as well as removal. Clark Pest Control offers a variety of solutions for your lawn and garden and can address problems you are having with both whiteflies and ants in your yard.
Physical Characteristics Paper wasps are large (1-inch long), slender wasps with long legs and a distinct, slender waist. Background colors vary, but most western species tend to be golden brown, or darker, with large patches of yellow or red. Behavior Preferring to live in or near orchards or vineyards, they hang their paper nests in protected areas, such as under eaves, in attics, or under tree branches or vines. Each nest hangs like an open umbrella from a pedicel (stalk) and has open cells that can be seen from beneath the nest. Paper wasp nests rarely exceed the size of an outstretched hand and populations vary between 15 to 200 individuals. Treatment Most species are relatively un-aggressive, but they can be a problem when they nest over doorways or in other areas of human activity, such as fruit trees. Call Clark if you are experiencing a problem with paper wasps on your property, our Pest-Away pest control service will take care of it.
Flies and Drains: What You Need to Know

When most people think of fly problems in commercial facilities, they tend to look up. They look for fly activity around windows, ventilation screens or loading dock doors. Rarely does anyone look down and that can be a problem.

Many small fly issues in restaurants, commercial kitchens and food processing plants are generated in the drains and plumbing that run beneath kitchen or production area floors.

Mike Biando, Associate Certified Entomologist, commercial QA supervisor for Clark Pest Control in Auburn, California, says commercial clients often overlook the role drains play in creating a condition conducive for small flies.

“Facility managers and business owners often don’t make the connection between drains and flies,” says Biando. “Drains that are not cleaned regularly allow organic material to build up and become ideal breeding grounds for small flies.”

Failing to make that connection can lead to damage to a restaurant, grocery store or food product supplier’s brand, and create a significant health threat by allowing disease and bacteria carrying flies to land on food or food preparation or serving surfaces.

What can excess food debris and water build up in a drain do? Biando says he recently visited a restaurant that had an issue with small flies and the owner was requesting more fly light traps. Upon further inspection, Biando noticed fly activity coming from one of the floor drains in the kitchen.

Biando showed the owner a drain that had significant organic material build up and was harboring flies.

“The owner thought the flies were coming in by the doors because that is where he noticed them,” says Biando. “The flies were actually trying to get out of the doors but were living in the drain.”

The Clark Pest Control solution included an application of a microbial foam product in the drain and surrounding tile area. The microbial treatment, one of several options in the fly management toolbox Clark deploys, can also be made under kitchen and food processing equipment, sinks and other areas where organic matter builds up and attracts flies.

How to Prevent Small Fly Issues

What can commercial facility and QA managers do to reduce their risk of having a small fly issue? Biando says the focus should be placed on the following areas:

Sanitation and Cleaning – Staying on top of sanitation and cleaning protocols reduces the amount of debris that can find its way into drains. Remind cleaning crews not to leave standing water when washing down floors. Water left overnight can seep into cracked floor tiles, grout and drains causing build up and creating a fly breeding area.

Structural Maintenance – Broken floor tiles, missing grout, baseboard tiles pulled away from the wall and leaking or broken plumbing pipes all are conditions that allow fly-attracting food debris and water to build up. Facility maintenance staffs need to stay current with repairs and be proactive by installing air curtains on loading dock doors, repairing vertical seals on double doors and ensuring there is positive airflow inside the facility.

Biando also recommends having a licensed plumber hydra-jet drains once a year and inspect them thoroughly to make sure they are intact. A broken drain pipe below a cement production floor will not only lead to a potential fly issue, but a significant repair bill and lost revenue due to the shutdown to fix the problem.

The Culprits

Drain Flies

  • Drain flies are tiny, which means they can penetrate screens and get inside structures easily. They’re weak fliers, although they can be carried by wind currents for up to 100 yards – the length of a football field.
  • You can find them resting inside on walls or near drain openings, and outdoors, in the shade. Often, their appearance is noted by their sheer quantity – a lot of them at once, clustering on lampshades, windows, sinks and floor drains in showers indoors, and outdoors in clogged roof gutters and storm drains, birdbaths, moist compost, potted-plant saucers and overgrown shrubs.
  • The larvae feed on fungi, sludge and microbes on the filmy surfaces of stagnant water, which may be why they have an appetite for organic matter in drains.

Phorid Flies

  • Phorid flies breed and develop deep within the plumbing of commercial facilities including restaurants and food processing plants. They can potentially taint food and food preparation surfaces with disease microorganisms.
  • Phorid flies have short and erratic flight patterns and are often mistaken for gnats. They are often seen running across windows, display screens, tables, walls, and plant foliage.
  • Resolving a phorid fly problem could require expensive repairs if the infestation stems from a plumbing leak underneath a floor.
  • Phorid flies will eat moist organic material that gathers in drains or other plumbing, decomposing flour on the floor and under equipment in bakeries and kitchens, and decomposing vegetables including potatoes and onions, fungi and other insects.

Reopening Your Business to Pest Control
29 May, 2020

Pests did not practice social distancing during the shutdown and as the state moves toward summer, historically the most active pest season, the need for effective pest management and disinfection services is essential.

As businesses reopen their doors across California, Clark Pest Control is working closely with commercial clients to help them safely welcome back both clients and workers and protect facilities from potentially harmful pests and harmful pathogens.

What is Clark doing to assist its commercial clients during this important time?

  • Clark QA inspectors and service technicians are performing top to bottom inspections of commercial facilities for signs of pests or conditions that encourage pest activity that may have developed during the shutdown period.
  • They are continuously communicating their findings from pest trend data and spatial mapping to facility and property managers, as well as ramping up monitoring efforts to identify what’s been going on inside a property pest-wise during the closure. It’s not always the pests we see that concern us, it’s the ones we don’t, and we must find the root cause of the issue.
  • Reinforcing the importance of “staying true” to the pest management program your facility had in place before it was shut down. This includes maintaining consistent cleaning and sanitation practices (poor sanitation is the leading cause of many pest issues), and considering expanding your program to include disinfection services.

During this pandemic, pests continued to seek access to reliable sources of food, water and shelter inside commercial facilities whether they were open or not. And if they did gain access, they easily slipped into a comfort zone because there were no threats to survival, and they had free run of the facility.

What were pests doing behind closed doors of commercial facilities? The Clark commercial team has seen the following trends emerge:

  • An increase in rodent activity in and around food service establishments as rats and mice scrambled to find new food sources when food waste and garbage stopped being put out in the dumpster.
  • As temperatures increased so did the pressure from Turkestan cockroaches. These roaches  need little in the way of food to survive but they need moisture and sought refuge in closed office buildings where they were undisturbed and could reproduce quickly.
  • Stored product pests enjoyed feasting on backlogged inventory of food products such as pasta or grains that have been stuck in limbo waiting to be shipped.

Safeguarding commercial establishments including grocery stores, office buildings, food processing and healthcare facilities from pests is more important than ever and ensuring the safety of customers, guests and employees is paramount. It’s the reason we do what we do at Clark.

Commercial facilities face both pest-related and disinfection issues as they reopen and neither one can be put aside or judged as more or less important than the other. Clark Pest Control has expanded its scope of service allowing it to deliver on both fronts for its commercial clients.

If you are looking for a pest management partner that delivers exceptional results and understands your business, and can help you protect your products, employees and customers from harmful pests, give Clark Pest Control a call at (800) 936-3339.

Stay safe and be well.

When applied at full strength in accordance with the product label, this powerful disinfectant will kill 99.999% of bacteria and viruses on hard, non-porous surfaces.


Our EssentialClean service protocol includes trained technicians carefully wiping down all high-touch surfaces in the treated area, then applying a misting application using specialized equipment and letting it dry undisturbed, typically for 10 to 15 minutes.

Wipe-down treatment – This application includes all inanimate human touch points, such as light switches, door handles, file cabinet drawer pulls, desk handles, and other locations. These areas will be treated with full-strength Vital Oxide using a microfiber wipe cloth.

Light-misting treatment – After the wipe-down application to touch points, we will treat the entire space with a fine mist application to ensure that all other areas have been treated.


Clark’s EssentialClean service is best rendered after hours, or otherwise when the building is unoccupied. In 24-hour facilities or other businesses that need to remain open during service, we can designate and treat unoccupied zones in rotation to allow most operations to continue during the service. (Note: A 10 x 20-foot zone can be treated in approximately 30 minutes, which includes application and drying time.)


Prior to treatment, customers need to remove dust and dirt from the areas to be treated so the treatment will have maximum impact, and place paper and other items that might be damaged from contact with a liquid mist into drawers or storage areas, or into out-of-the-way trash bags. Exposed food should be stored, and while you don’t need to do anything with electronic equipment, we will limit treatment to the wipe-down method for all electronic display monitors, computer terminals, TVs, electric motors, wiring, or circuits.


The disinfectant product we use is rated by EPA as Toxicity Category IV, its lowest toxicity rating, defined as “practically non-toxic and not an irritant.” It contains no ozone-harming volatile organic compounds (VOCs), and is mild on skin, hard surfaces, and fabrics.


No. The product we use is rated “no rinse required on food contact surfaces” category D2 by NSF International, meaning it is approved for use in commercial or residential kitchens to control bacteria, viruses, and mold without the need to wash or rinse the area with water after it is applied.


The safety of our employees and customers is our highest priority. We selected the product Vital Oxide partly due to its high efficacy, and partly due to its very low toxicity (see above). Our technicians are trained to follow all personal protective equipment (PPE) guidelines on the product label, but also are trained to wear PPE in potentially unsafe or contaminated environments.


After being applied at full strength in accordance with the product label, we let it dry undisturbed, typically for 10 to 15 minutes, at which point the product will have eliminated 99.999% of all bacteria and viruses on hard, non-porous surfaces.

Like any other disinfectant treatment, surfaces can be re-contaminated after treatment. You should not believe any service provider or product manufacturer who claims that their product or treatment “kills COVID-19 for seven days” or similar. It simply isn’t true.

With that in mind, you may want to consider weekly treatments of high-traffic areas to lower the risk of surface contamination and disease transmission, or immediate treatment of areas that have been occupied by someone showing COVID-19 symptoms.

Pest Management Is Essential to Business
16 April, 2020

These are certainly unique times. Commercial enterprises, big and small, are feeling stresses from the COVID-19 crisis, and things are far from normal for those who operate businesses.

Clark Pest Control’s number-one priority is protecting the world where our employees and customers live, work, and play. Maintaining a healthy and abundant food supply is also critical during these times, and pest management services are essential to achieving that goal.

While Clark stands ready to support our commercial clients, we also realize that safety is paramount. We have a longstanding partnership with the Centers for Disease Control and Prevention in mitigating pest-related health risks, and we have procedures and protocols in place to address issues that may arise during this crisis.

Our licensed technicians are trained, tested, and certified in the use of personal protective equipment (PPE), including respirators, eye protection, gloves, and protective clothing. When servicing facilities, we will use every means possible to deliver our essential services in a manner that fosters safety as well as effective pest management.

Why are pest management services essential for commercial properties? Here are some reasons:

  • Stinging insects force half a million people to the emergency room every year.
  • Cockroach and rodent allergens trigger asthma attacks in children.
  • Pests spread pathogens for such diseases as West Nile virus, Lyme disease, listeria, salmonellosis, hantavirus, and encephalitis.
  • Rodents contaminate or consume about 20 percent of the world’s food supply.
  • Bed bugs can cause allergic reactions.

In commercial food processing, distribution, and service facilities, the presence of pests – whether they are rodents, flies, cockroaches, or others – can be devastating. Pests can spoil and contaminate food, making it unsafe for consumers. A pest-related contamination can trigger a product recall that not only causes financial hardships, but makes that product unavailable for consumers.

Healthcare and key manufacturing facilities cannot risk being shut down due to a pest infestation. The importance of the pest management industry to the nation as an essential service cannot be overstated.

During this crucial time, Clark would like to remind commercial facilities of the following:

  • Maintain your pest management programs: Don’t allow your pest management programs to slip or get put on the back burner as you deal with other issues. If a pest infestation takes hold, especially in a food processing plant, the impact will be far-reaching for both your company and the community at large.
  • Open facilities for regular inspections: Even if you temporarily close your facility, allow your pest management service provider to continue regular inspections to make sure that pests haven’t invited themselves inside.
  • Stay on top of sanitation and cleaning protocols: This reminder never changes, but stay on top of sanitation and cleaning practices. The leading cause of pest infestations can usually be traced back to a sanitation issue, so it’s more important than ever to make sure this is priority one.
  • Work as a team: More can be accomplished working together in times of crisis than separately. Your pest management service provider is your partner to maintaining a pest-free environment for your facility, employees, and customers.

If you’re looking for a pest management partner that delivers exceptional results and understands your business, and can help you protect your products, employees, and customers from harmful pests, call or text Clark Pest Control at (800) 936-3339.

Never Forget About Sanitation
16 March, 2020

If you ask a veteran pest management professional, QA manager, or third-party auditor what the likely root cause of most pest infestations is, we can guarantee that poor sanitation is going to be at the top of the list.

The simple fact is that if your facility does not have established and consistently reinforced sanitation and cleaning protocols, it will be at a higher risk for a pest infestation.

Sanitation is a core principle of an integrated pest management (IPM) program, and it’s important for employees, from the c-suite to hourly workers, to appreciate its importance. Many pest problems in commercial facilities can be reduced, or even prevented from occurring, if employees ensure that proper sanitation practices are followed.

The more cooperation that is received from maintenance staff – including internal or contracted cleaning services, supervisors, and front-line employees – the better the results of your pest management program will be.

Food processing, distribution, storage, and service facilities are aware of the value of having strong sanitation protocols in place to meet today’s more stringent regulatory and audit requirements.

Facilities that have their sanitation and cleaning programs in order are likely to run more efficiently, perform better financially, and are less likely to be threatened by pests.

The management of these facilities understand that sanitation and cleaning are the most important programs they oversee, and if protocols are not being followed correctly or performed consistently, the risk for pests rises.

In addition to quality loss through product adulteration and consumption by pests, poor sanitation and cleaning practices also increase the risk of a poor or failed audit or inspection, putting your products, employees, and customers at risk.

The downstream impact can also be detrimental to your business in several ways:

Damage to your brand(s) in the eyes of consumers

Financial losses from products being rejected by clients, product recalls, or the inability to sell your products to suppliers

The costs for additional or repeated sanitation services

The cost for additional (and unbudgeted) pest management services beyond the scope of your service agreement due to an unplanned infestation

What is effective cleaning?

An effective cleaning program is a formalized, documented process, not just pouring a chemical onto a surface, wiping it around, and declaring that the surface has been cleaned, disinfected, and sanitized. That won’t cut it.

For sanitation and cleaning protocols to be effective, they must be done consistently, but also done correctly. That is why a documented program is a must-have, because it can measure the effectiveness of your efforts and allow for corrections.

A comprehensive and effective cleaning typically will include the following three-step process.

  1. Washing: The function of the wash step is to ensure that the cleaning agent makes contact with the soil on the surface, to remove soil from the surface and keep it away from the surface.
  2. Rinsing: Thorough rinsing is essential to remove the cleaning agent. Rinsing may also continue the cleaning action.
  3. Drying: The drying step removes excess moisture (an attractant to many pests) and volatile residue.

What are some often-overlooked issues that contribute to sanitation issues?

Deep cleaning of equipment: In addition to floors, drains, and preparation surfaces, all equipment (e.g., sifters, conveyors, grinders, extruders, mixers) should be on a regular cleaning schedule, but that schedule also needs to include the deep cleaning of inaccessible areas. These areas often require machinery to be shut down, and are difficult to access, but doing so is essential to an effective sanitation and pest control program. A plant can have the cleanest floor around, but if food debris is left behind in a piece of processing equipment, pests will likely find it.

Equipment boneyards: These areas are often where non-functioning or outdated machinery is put. Unfortunately, equipment there is often not cleaned prior to moving, and can be a haven for pest populations. These areas also often provide harborage for rodents.

Air curtains, door seals, and screens: All access points to the food processing plant need be designed with pest prevention in mind. These would include air curtains on all exterior doors, screens on all windows, complete seals for dock-loading areas, etc. Also included should be a periodic inspection of these areas to ensure they are maintained in great condition.

The rock by the exterior doors: That rock used to prop exterior doors open for employee breaks can lead to a very common route of entry for all sorts of flying and crawling insects, which will wreak havoc on any sanitation or pest control program.

Inspection program for incoming shipments: Shipments should remain in some sort of quarantined area until they are inspected, and prior to entering the actual plant.

Think big picture: Having a master documented sanitation schedule is going to be critical to ensure that all areas of the plant are cleaned/sanitized on a regular basis.

Proper weed control: Without this, insects and rodents have a great area to infest, hide, and breed on the exterior of the facility. As populations increase, so will interior infestations.

Good sanitation also involves more than cleaning – it involves data. Make sure to partner with a pest control company that does more than just check devices. Ideally, the company will conduct regular inspections, quarterly evaluations, and annual risk assessments, and will use the data collected to heat-map potential problem areas. It will perform inspections of those areas to identify sanitation or exclusion issues that contribute to the problems noted, and will communicate that info back to their contact in the food plan, who will then ensure that all issues are corrected.

Pests and sanitation issues are interchangeable. If you have one, you likely will have the other. Developing a strong partnership and cooperating with your pest management provider to identify vulnerable areas and conditions, take the necessary corrective action, and document the results are musts.

Managing Pests Through Vegetation Management
24 January, 2020

by Fred Speer

A well-maintained landscape adds to the curb appeal of a commercial facility, but it can also contribute to unwanted pest pressure and an increased threat of pests gaining access to your facility and negatively impacting products and people.

What do landscape plants, bushes and trees and pest pressure have to do with one another? Landscaping can create a living space for a variety of pests including rodents, ants, termites, cockroaches, certain species of beetles and stinging insects.

As summer winds down facility and property managers need to include vegetation management in their maintenance schedules.

Mike Andrew, manager, corporate agriculture quality assurance for Clark, says fall is the time make sure weeds and other vegetation is cleared through proper landscape management practices and the use of post-emergent herbicides.

“You want to make sure your grounds are cleaned up and weeds do not have the chance to germinate before the winter rains come and they take hold,” says Andrew. “Overgrown vegetation close to structures not only offer pests like rodents, gophers and squirrels harborage but an easy food source as well.”

Andrew says the application of pre-emergent herbicides in late fall and early winter will help prevent weeds from becoming an eye sore and a detriment to your grounds in the spring.

There are other ways facility and property managers can lessen the threat of pest pressure caused by overgrown or poorly maintained vegetation.

Smart Landscape Design

Facility and property managers can mitigate the threat of pests taking advantage of the landscape around a structure by making sure the landscape is properly designed.

Pests will use shrubs, ornamental grasses, plants, trees, mulch, leaf piles and landscaping debris as a nesting site and staging area to attempt to access a facility. This close-in proximity to loading dock and entry doors, windows, utility openings, and HVAC and ventilation openings can be a real headache.

While mulch may look attractive, it holds moisture and is attractive to cockroaches, ants, spiders, beetles, and termites. Maintaining a two-foot band that is free of grass, plants, or other organic material around the foundation will help create an unattractive pest buffer zone.

The sweet, sugary sap that certain plants produce is an attractive food source to ants and stinging insects as are the aphids that also come to feed off the plants. Fruit trees, date palms, Algerian ivy and boxelder trees are great examples of food sources that are very appealing to many insects. Remove their shelter and food and you’ll reduce pest pressure.

Stay on Top of Maintenance Work

Standard maintenance practices including regular grass mowing, trimming trees and bushes, removing weeds, and thinning out or replacing densely overgrown shrubs and bushes with less dense varieties will help reduce pest drawing cards.

Tree limbs, bushes, and vines touching a structure provide can give pests such as roof rats (a growing problem on the West Coast), squirrels and ants access to exterior wall and roof vents and openings where they can gain entry.

Excess moisture is another attractant for pests and maintaining a positive airflow around plants located near the structure will help prevent moisture build up.

Repairing broken sprinkler heads, sloping ground away from the building, directing sprinklers and downspouts away from structures, and using stone, rock, or other non-absorbent landscape materials will also prevent pest-attracting standing water or excessive moisture build up

Look Up, Down and Around

When performing an inspection to identify landscape conditions that could attract pests, make sure to take a 3-D view - not just ground level, and examine the structural well-being of your facility.

Identify cracks and openings in the foundation, around window and door openings, missing or torn screens, and openings around gutters and roof systems that give pests a chance to get inside.

Inspect equipment ‘boneyards,’ seldom used exterior storage areas, and waste management areas. Weeds and overgrown shrubs in these areas provide attractive harborage locations that can allow pest populations to grow unchecked.

Make note of any structural items that need to be corrected and make sure the work is completed in a timely fashion.

Rising Rodent Pressure Spurs a Call to Action
17 December, 2019

It comes as no surprise to business owners that rodent activity is on the rise all along the West Coast, especially in California. The evidence of their presence in and around commercial properties can be all too clear.

This increased pressure presents a potentially serious threat to commercial facilities, especially those engaged in food processing, distribution or warehousing.

Clark Pest Control rodent specialist Richard Park, A.C.E., says Clark technicians and inspectors have observed increased rat populations in major metropolitan areas including San Francisco, Los Angeles, Sacramento and Long Beach.

How intense is the problem? Park says he came across a situation in a downtown area where garbage collectors had to close the windows of their trucks when emptying dumpsters for fear of a rat (or two) falling out and landing in their truck cab.

“The simple task of failing to secure a dumpster lid is an open invitation for rats and when you have multiple dumpsters in an alley, it can ramp up rodent pressure outside your back door in a hurry,” adds Park.

There are several factors driving the rodent population boom including:

  • Rodents are being forced to find new sources of shelter and food due to wildfires destroying their natural habitats.
  • Mild, wet winter weather allowed rodents to breed longer and reproduce in greater numbers, and feed on robust vegetation whose growth was spurred by the wet conditions.
  • Commercial property managers and owners not recognizing or reacting quickly enough to physical and cultural conditions conducive to rodents.
  • Increased homelessness in crowded urban areas leads to more rodent/human encounters as rodents take advantage of easily accessible sources of food, water and shelter.

The type of rodent commercial clients encounter depends on where you are in the Golden State. In Northern California, you will see more roof rats and house mice, and in Southern California Norway rats are more prevalent.

What can commercial clients do to stem the tide and keep from having rodent issues in and around their facilities?

Park says the first step, even if you just suspect you might have an issue, is to call Clark for a free rodent assessment for your facility. The assessment will include a thorough inspection of your facility, inside and out, and a report outlining any structural, cultural or procedural deficiencies that would allow rodents access.

“The assessment is done to help property and facility managers understand where the weak spots and deficiencies are within their structure,” says Park. “We want to educate them and have them to take proactive steps, if needed, to head off any rodent issues and avoid a poor or failed audit or having product shipments damaged or rejected by clients.”

Based on the assessment findings Clark will recommend treatment options that emphasize a comprehensive exclusion program. An exclusion program limits rodent access to a structure and can be a long-term solution to a rodent (or pest problem).

Rodents need very little space – the size of a quarter for rats and a dime for mice – to enter a facility so building a defensive perimeter is a worthwhile investment.

What Does Rodent Exclusion Look Like?

Rodent exclusion is your first line of defense and can be handled by your maintenance staff, your pest management service provider or a combination of both. If either party sees a condition that is conducive to rodents, it should be addressed ASAP.

Identify and seal gaps that give rodents an easy pathway inside. Look beyond the obvious areas – windows and loading dock and entry doors, and to vents, pipes, utility openings, cracks in the foundation and openings on the roof.

Sealing up your building will include the following:

  • Repair or replace all torn or missing window and door screens.
  • Replace old or missing weather stripping
  • Install door sweeps to help create a barrier against rodents. They close gaps under entry and loading dock doors with thousands of dense nylon bristles.
  • Use water-resistance sealant or adhesive to fill in cracks, crevices or gaps in your foundation that could give rodents a way inside.
  • Repair or replace broken or missing vent covers with rodent-proof material.

“Commercial clients need to understand they are up against a determined, resourceful opponent in rodents,” says Park. “Preventing or eliminating a rodent infestation requires identifying the root cause of the threat, correcting it and above all being proactive to stop it in the first place.”

Five Ways to Prevent Rodent Infestations

  1. Have a free rodent assessment done for your facility
  2. Use exclusion as a first line of defense against rodents
  3. Stay on top of sanitation and cleaning protocols
  4. Carefully inspect incoming shipments for signs of rodents
  5. Stay on top of structural and landscape management practices

Occasional Pest Pressure Rising with the Temperatures
17 July, 2019

by Fred Speer

If occasional pests were just that – an occasional headache that property and facility management had to worry about – then it wouldn’t be a big deal. That’s not the case, however, for many commercial facilities, especially those involved in food processing, service, or storage/distribution.

The presence of any insect or pest in or near these facilities can lead to poor or failed audits, contaminated products, bad publicity, and lost revenue/profits.

While summer officially arrived on June 21, the weather has been summerlike for some time in California, and that is leading to increased pest pressure in and around commercial facilities.

“A warm and wet winter followed by a rapid increase in temperatures has led to greater numbers of occasional pests,” says Mark Myers, commercial sales manager for Clark Pest Control. “The numbers are much larger than we usually see this time of year.”

What exactly is an occasional invader? The term occasional invaders is a catchall term for a group of pests that invade structures from time to time, because outside weather conditions have become hostile to their survival.

In this case, it’s the sudden rise in temperatures and loss of moisture that many of these insects need to survive. What pests fall into this group?

Occasional invaders are active year-round, and will spend the majority of their time outdoors and be nothing more than a nuisance. But, as mentioned earlier, weather conditions (e.g., excessive heat, dry conditions) will motivate pests to seek shelter inside structures, and that’s where the risk lies.

Preventing problems with occasional invaders

How can property, facility, and QA managers prevent occasional invaders from becoming a problem in their facilities? Myers says eliminating sources of food, water, and shelter that attract occasional invaders is the first step to preventing any issues.

The second step is to stay on top of the facility’s cleaning and sanitation practices. Myers says facilities can have varying production schedules and need to clean processing equipment thoroughly between usage and before storing it.

“We’ve seen instances where processing equipment was put in the boneyard before it was cleaned, and it became a readily available source of food and breeding ground for a variety of pests,” says Myers. “This led to infestations occurring at non-traditional times of the year. That’s why staying on top of sanitation and cleaning protocols is essential.”

The third step in preventing occasional invaders (and other pests) from gaining access to a structure centers on performing thorough inspections of incoming shipments.

“Stopping hitchhiking pests on the loading dock before they can gain entry inside is critical,” says Myers. “Once they get inside and the threat of natural predators is eliminated, they can hunker down and become a real problem.”

Myers says two pests that have become resurgent lately are psocids and Turkestan cockroaches. Clark technicians have found the hard-to-detect psocid in the lids of 55-gallon storage drums that can be easily (and unknowingly) transported into facilities.

Turkestan cockroaches primarily live outdoors near bodies of water, in electrical meter boxes, or in cracks in concrete, but they can be found indoors when their population levels peak in the summer. They will be attracted to exterior lights and can fly into structures.

“The Turkestan cockroach is not as frequently encountered as is the German roach, but in today’s global supply chain, the chance for invasive pests being introduced into facilities is much greater,” adds Myers.

The final step for facility and property managers to be aware of when it comes to occasional invaders is making sure they stay on top of landscape management practices.

“Landscape plants and trees can be incubators for pests and need to be regularly maintained,” says Myers. “Keep grass cut, trim shrubs and trees, don’t overwater, and maintain a plant and mulch-free barrier [18 to 24 inches] around the foundation to deny pests a close-in access point to your facility.”

Four tips to remember

  1. Remove sources of food, water, and shelter
  2. Stay on top of sanitation and cleaning protocols
  3. Carefully inspect incoming shipments for signs of pests
  4. Stay on top of landscape management practices

Breaking Down the Difference Between Pest Prevention and Pest Control
14 June, 2019

by Fred Speer | 06/04/2019

Pest control of yesteryear was basic in its premise: If an insect or rodent was observed in a facility, the pest control company came up with a way to eliminate it. There was more to the process but it was very much a reactionary process.

Oh, how things have changed. Today’s pest management protocols start with preventive strategies designed to keep pests from accessing facilities in the first place and becoming an issue.

This approach is driven by mandates set forth under the Food Safety Modernization Act (FSMA) that stress pest prevention first. A preventive mindset compliments a facility’s integrated pest management (IPM) program that includes good sanitation protocols, exclusion, cultural practices and landscaping that discourages pest habitation.

Clark Pest Control visited with noted commercial pest management strategist and consultant Dan Collins B.C.E., to get his take on the difference between a pest prevention program and a pest control program.

What is the difference between pest prevention and pest control?

Pest prevention is a proactive approach to keep pests out of a facility and pest control is a reactive response – the application of pesticides or the deployment of baits and traps – to eliminate a specific pest threat.

“Pest prevention is a more comprehensive approach that includes a variety of elements including trend analysis, sanitation and cultural practices,” says Collins. “It looks at things from the 30,000 ft. level.”

A preventive approach defines what the client is responsible for, what the pest management professional is responsible for and makes sure both parties are fulfilling their responsibilities.

Pest control is more tactical and ground level and can include checking traps, changing bait, etc.

How are clients involved in the process?

Clients are a key part of the pest prevention process and the level of buy-in, from the c-suite to the loading dock, will often determine the effectiveness of your pest program.

What are some examples of pest prevention? They include:

  • Determining who is responsible on staff for inspecting incoming shipments for signs of pests.
  • Establishing a uniform cleaning protocol so employees don’t accidentally bring pests inside a facility and introduce them to locker room areas.
  • Determining what areas of a plant should be wet washed rather than dry washed to reduce moisture attracting pests like cockroaches or flies.
  • Making sure the physical condition of the plant is solid and that basic maintenance tasks – installing door sweeps or sealing expansion joints – to keep pests out are being taken care of.
  • Locating dumpsters away from entrances and making sure they are cleaned regularly.
  • Conducting regular wellness checks of your program with your pest management service provider to make sure it is working as it should.

Reaping the Benefits

While pest prevention does require a bigger investment of time, people and resources on the front end, once the system is in place it becomes second nature and lessens a facility’s pest exposure.

Plant and QA managers, as well as upper management, want to avoid product recalls or not have product shipments rejected by clients because of a pest-related issue. Not only is this costly to the bottom line but to a company’s brand reputation as well.

“If pest prevention programs are in place there will be no knee-jerk reactions should an issue come up,” says Collins. “It allows facility and QA managers to better manage and reduce risk.”

How long does it take to transition to a pest prevention program? Collins says it depends on the size and complexity of the plant and what products are produced at the facility.

“There are many variables involved but it should take about 60 days to make an effective transition,” says Collins. “Once in place you won’t constantly have to put out fires when it comes to pest-related issues. You’ll be ahead of the game.”

Plants will also stay in line with the fundamental mandates of FSMA and that should bring a smile to the faces of facility and QA managers and their bosses.

Employee training is another important element to a successful pest prevention program. It is important to explain to employees how their actions impact the program and understand why it is necessary to have a program in place and set up a certain way.

“Explaining why they are being asked to do things a certain way and how their efforts lead to improved quality and higher levels of food safety will make it easier to understand and secure their buy in,” says Collins.

This is Pest Prevention….

  • Conducting risk assessments and frequent inspections
  • Eliminating conducive conditions
  • Conducting practice audits
  • Establishing sanitation protocols including equipment cleaning
  • Staying on top of facility maintenance
  • Exclusion practices (i.e. door sweeps)
  • Employee training
  • Pest monitoring and trend analysis
  • Effective communication between facility employees, management and pest professionals regarding pest issues and conducive conditions

This is Pest Control….

  • Deploying pest control equipment
  • Targeted application of pesticides
  • Checking traps for activity or changing bait stations

Of course, even with a proper pest prevention program, pest control will still sometimes be necessary as specific needs arise. When this happens, properly analyzing what led to an infestation can actually help bolster future pest prevention efforts.

Under Pressure to Deny Access to Pests
24 April, 2019

by Fred Speer | 04/01/2019

If you were a fan of the Academy Award-nominated movie Bohemian Rhapsody, based on the epic career of the rock band Queen, the song “Under Pressure” should be quite familiar.

What, in the name of Freddie Mercury, does this have to do with pest management, you may ask? Under pressure is what commercial facilities – especially ones involved with food processing and distribution – may be facing as spring arrives and pest pressure rises.

California’s unusually wet winter, with record amounts of rain and snow, has created favorable conditions for a variety of pests that need moisture to survive. And while overwintering pests are busy breeding in the wet soil, that moisture will soon give way to warmer, drier conditions.

When this takes place, pests – rodents, ants, house flies, and various occasional invaders like crickets, earwigs, and silverfish – will likely emerge in large numbers and begin foraging in search of new sources of food, water, and shelter. One of the first places they will look to invade is your plant or warehouse.

Where is the pest pressure in commercial facilities the greatest so far in 2019? A review of year-to-date pest trend data collected by Clark revealed the following:


The locations with the most activity on both the interior and exterior of commercial accounts were found in northern California – Yuba City and Chico – and the central coast city of Santa Maria.

All three feature facilities that process large volumes of raw commodities – rice, coffee, and tree nuts – which rodents are attracted to. And while activity so far in 2019 is strong, it’s down from a year ago, primarily due to the abundance of natural food and shelter sources (e.g., vegetation, excess moisture) in these more rural areas.

Occasional invaders

When it came to occasional invaders such as earwigs, house flies, and silverfish, facilities in and around Livermore, Merced, and Milpitas registered the most activity. Livermore and Milpitas feature dense clusters of commercial facilities embedded in highly populated urban environments, with high amounts of exterior lighting – an attractant for occasional invaders.

Stored product pests

Chico-area commercial facilities tallied the highest amount of stored product pest activity, and this can be attributed to the nature of the food processing activity – large volumes of raw commodities – in the area.

How can commercial clients safeguard their facilities from the looming rise in pest pressure?

Jeremy Kluge, commercial sales manager for Clark in Auburn, California, says that a proactive and systematic but adaptable approach is required.

“We are working with clients,” says Kluge, “to ensure their sanitation and exclusion practices are in place and working, [that] they are practicing sound inventory management [first in, first out], and [we are] stressing the importance of incoming shipment inspections. We are also talking with them about exclusion to build an effective barrier to keep pests out.”

Clark is also studying pest trend data to see where and when pest activity in taking place, and what has happened in the past.

“The use of trend data has changed the way we approach designing and implementing pest programs for clients,” says Kluge.

The focus has shifted from being reactionary to proactive, identifying the root cause (e.g., poor sanitation, cultural issues) of a pest issue and adjusting the program to attack the problem and prevent it from happening again.

The spring commercial client preparedness checklist

  • Perform a thorough exterior inspection of your facility – including the roof – with your maintenance staff and pest management service provider to identify areas where structural repairs and exclusion practices need to be performed.
  • Clean out and make sure dumpsters have lids that close tightly to deny pests an easy meal or harborage location.
  • Maintain good landscape management practices to eliminate pest nesting sites and food sources.
  • Take corrective actions before pest populations emerge in large numbers and become harder to control.

The Impact of the Swabathon on Food Safety

To combat harmful pathogens – including Salmonella and Listeria monocytogenes, both of which have been at the center of recent food recalls and outbreaks that have sickened consumers – the Food and Drug Administration and food plant managers are turning to “swabathons” to help establish a higher level of food safety.

What is a swabathon? It’s when a regulatory agency, usually the FDA or an independent laboratory, comes to your plant and takes multiple swab samples from equipment, floors, and surfaces. Hundreds of swab samples can be taken to identify areas vulnerable for transient contamination, or that might promote growth of harmful pathogens.

A swabathon can take several days to complete. It can be announced or unannounced and can be prompted if food products from the plant were linked to an outbreak or can simply be done at random. Plants producing ready-to-eat and high-risk commodities, such as dairy products. are more likely to have a swabathon done.

Why is a swabathon necessary? In the past, the FDA would collect product samples for laboratory testing of finished product, but inspectors are looking to be proactive and will use more comprehensive environmental testing (i.e., a swabathon) to determine if a threat is present.

Once harmful pathogens establish themselves in a piece of processing equipment, or on a food preparation surface, the potential exists for contamination of food products that come into contact with these areas as they make their way through the production process.

The ultimate goal is to be able to identify potential hazards sooner, and to offer an advanced level of protection for consumers.

What happens to the samples?

Following the FDA’s visit, the samples will be analyzed for listeria or salmonella. If either is present, the FDA will genetically type it, using a process called whole genome sequencing. The genetic data information is then entered into GenomeTrakr, the FDA’s national database.

The FDA will determine if the strain has been seen before, and if it links back to an ongoing outbreak of Salmonella or Listeria in food or a food plant. If a match is found, it’s highly likely that a product recall will be issued. The test results remain in the FDA database for several years – even if the bacteria found isn’t matched to a current outbreak – and will be compared against future outbreaks or illnesses.

How to prepare for an inspection or swabathon

  • Make sure your food safety plan meets FDA’s regulatory requirements
    • Is your documentation well organized and accessible?
    • Are you documenting what you said you would do?
  • Do you have a culture of food safety?
  • Conduct practice inspections
  • Update your inspection manual
  • Who is going to be present during the inspection or swabathon?
    • Which employees will accompany the investigators?
    • Who is going to be on call to answer questions?
  • Swabathon specific actions
    • Decide your company policy on companion/sister/duplicate sampling
    • Do you have the resources lined up (personnel, equipment, lab availability)?
    • Decide whether to hold product for zone 1 samples
  • During the Inspection/swabathon
    • Accompany the inspectors
    • Take immediate corrective actions
    • Take detailed notes
    • Mark records confidential, commercial proprietary information, or trade secret as appropriate

Inspectors are likely to ask plenty of specific questions, so be prepared to discuss your food safety plan, sanitation, and pest management protocols.

If you are looking for a pest management partner that understands your business, can help you prepare, and be present during a swabathon or inspection, call or text Clark Pest Control at (800) 936-3339.

Production Facilities: Winter Pest Update
14 March, 2018

Spring officially arrives on March 20. However, unseasonably warm weather in California and parts of northern Nevada has caused some pests in and around commercial facilities to act confused, while other pests are acting like one might expect.

Greg Ingram, A.C.E., a corporate QA manager for Clark Pest Control, says he has witnessed a spike in mosquito and flying insect activity recently, something that Clark pest experts typically don’t see until spring.

“California and northern Nevada enjoy a variety of micro-climates that can impact not only the type of pest you might encounter, but where and when you encounter them,” says Ingram. “This winter, we have seen earlier activity with some non-seasonal pests, and slightly increased activity of more traditional winter pests – including rodents and wildlife.”

Abundant rain from the winter of 2016-2017 yielded an increase in plant growth, which helped to provide plentiful sources of food and harborage for disease-transmitting and destructive commensal rodents – mice, Norway rats, and roof rats.

With more places to eat and live on the exterior of a commercial facility, rodents improved their chances of gaining access to the holy grail of more food, water, and shelter on the inside.

And when colder temperatures and drier conditions arrived this winter, eliminating the rodents’ natural food sources, their first move was to use that proximity to structures to their advantage.

“This placed an emphasis on making sure our commercial facilities were focusing on pest exclusion and eliminating conducive conditions that could attract them,” says Ingram.

Ingram says three common conditions that attract pests to a facility in the winter include:

1. Deficiencies in a facility’s sanitation programs

2. Structural deficiencies, such as missing screens, openings in the foundation or roof, lack of door sweeps, loose seals on doors, windows, etc.

3. Excess clutter inside and outside the facility (i.e., overcrowded storerooms, stacked wooden pallets, etc.)

Another factor that helped increase pest pressure in certain areas is the havoc wreaked by California’s wildfires, flooding, and mudslides.

“The natural habitats of rodents and other pests were disrupted by these events,” says Ingram, “and as a result, they went in search of more welcome environments – usually the closest structure.”

To keep pests out of your facility this winter (and all year around), Ingram recommends the following:

  • Take preventive action in the fall months to correct conditions that attract pests and allow them to gain access to your facility.
  • Get outside and perform a thorough inspection of the exterior of your facility with your maintenance staff and your pest management provider, so that you can identify items that need correction.
  • Create a defensible space around your facility by reducing excess landscape plantings and other conducive conditions.

If you are looking for a pest management partner that understands your business and can help your company create a culture of food safety, as well as deliver exceptional results and outstanding client care, call or text Clark Pest Control at (800) 936-3339.

Wineries: The Trendy Methods of Modern Pest Management
25 September, 2017

With the third-party auditing being more and more subjective, it would serve food processing, storage, transportation and distribution facilities and their pest management partners well to insert a hefty dose of sound science into the discussion.

Part of this sound science approach relies on the collection, interpretation and sharing of pest trend reports. These reports are gathered with intelligence gleaned by technicians from monitoring insect and rodent traps within facilities, first-hand observations, review of pest logs kept by the client and conversations with facility staff.

Trend reports share information on pest activity and evidence of their presence (i.e. rodent droppings, gnaw marks on packaging, dead insects, etc.) within a facility.

These reports not only tell a pest management professional and facility staff where pest activity is present and how great the pressure but when pests are most likely to be active based on history.

The proper analysis of trend reports is something the commercial pest experts at Clark Pest Control thrive on. We sift through mounds of data collected from our clients to identify pest trends and use that data to get ahead of potential issues.

Pests, like humans, are creatures of habit and through trend report analysis we can predict when Indian meal moths may be an issue or from what access point rodents are entering a warehouse.

By combing our expertise in pest prevention and elimination with trend data we can deliver a more comprehensive and complete pest program.

Under mandates of the Food Safety Modernization Act (FSMA) food processors and their pest management partners are being required to take a pro-active approach to pest management and food safety.

Written pest management programs are required to be developed and carried out in food processing facilities both big and small. And the programs must place a strong emphasis on adopting a proactive, preventive – not reactive – approach to pest management.

Pest trend reporting and analysis falls in line perfectly with this approach, and can provide all stakeholders involved in the process – food processors, pest management providers, auditors and inspectors – with accurate, detailed and current information.

Clark Pest Control has always been committed to deploying cutting-edge technology to solve clients’ pest issues and trend reporting is part of that. These examples of trend reports show how we gather and disseminate valuable pest data for the benefit of our clients. 

Under Pressure: A Look at Spring Pests in the Winery
09 May, 2017

California’s wet and wild winter certainly was a departure from the dry and unusually warm winters the state has endured over much of the preceding decade. But what will the change in weather mean for pest pressures this spring and summer?

Water – along with food and shelter – is one of the three basic staples that insect pests need to survive. Cockroaches, flies, and ants are only a few of the pests that flourish when they have consistent access to water, which keeps them from drying out. Abundant water also factors into where they instinctively locate harborage and nesting sites.

The Clark Man visited with Darren Van Steenwyk, B.C.E., Technical Director for Clark Pest Control, to see what impact this winter’s weather will have on pest pressures this spring. Here’s what he has to say:

“Based on the extremely wet weather we experienced this winter, it is possible that homeowners could see increased pest pressure this spring,” says Van Steenwyk. “Spiders could be more of a nuisance, and there is good chance we will see more small flies, due to increased moisture levels and decaying organic matter as a result of flooding and standing water.”

Clark Pest Control’s technical point man also thinks this year’s termite swarms could be more prevalent, due to moist soil conditions that are music to subterranean termites’ ears. These destructive pests silently attack structures from well-hidden nests that are entrenched in the soil beneath homes and other structures.

Other soil-dwelling pests, such as crickets and earwigs, may also experience a renaissance due to the moist conditions that exist.

One pest that may suffer a setback because of the wet conditions is also one of California’s most commonly encountered pests – ants.

These insects, like the Argentine ant, do need moisture to survive. However, heavy flooding may have wiped out their underground nests. Also, such food sources as grasses and plants, on which the ants feed, may be getting choked out by weeds that are thriving due to the wet conditions.

What can you do to deflate spring pest pressures due to excess moisture? The Clark Man offers the following tips:

  • Eliminate standing water 
  • Repair leaky faucets and irrigation sprinkler heads and pipes
  • Make sure attics and crawlspaces are well vented
  • Clean out leaves from gutters to avoid water buildup

Ending the Romance for Stored Product Pests with Mating Disruption
10 April, 2017

Stored product pests are one of the most economically important pests for food processing facilities such as grain silos, bakeries, breweries and retail food stores that store or use large amounts of unprocessed and cereal based grain products.

Confused flour beetles, Indian meal moths, saw-toothed grain beetles, weevils and other stored product pests can infest and spoil grain, flour, rice and finished goods rendering products inedible. This causes downtime in production, damaging the brand name and creating negative consumer feedback. If noticed by a third-party auditor, causes a facility to receive a reduced score or even failure of their audit.

One method for controlling stored product pests that threaten food processing and storage facilities is mating disruption. Scientist are working on several mating disruption materials, the one currently available and highly effective is for Indian meal moths and related food moths.

Mating disruption is the process of introducing artificial sex attractant pheromones into a facility with the intention of distracting male stored product pests – Indian meal and flour moths mainly – as they are trying to make a love connection with their female counterparts during mating season.

The artificial pheromones create “false trails” that make it harder for male moths to find their soul mates and when that happens mating doesn’t occur, eggs are not laid and the populations of these destructive pests drops.

Female Indian meal moths communicate with males through pheromone plumes. This directs male moths to their location. By using the mating disruption pheromone, the males chase a false trail, exhaust their energy reserves and die before successfully finding and mating with a female. These disruptions have a significant impact on their ability to mate and reproduce.

Even though pheromones products are naturally occurring this particular application method makes them a registered pesticide. However, they are certified for use in organic food processing facilities and there is no danger of food product absorbing the pheromones unless it comes in direct contact with the dispenser.

Pheromone mating disruption dispensers are typically installed and replaced twice a year to ensure coverage through the entire moth mating season. The dispensers are placed within facilities and can treat an entire warehouse but they have also proven successful in treating specific sections or even aisles in a facility.

A thorough pest monitoring program is also a key part of the process. Deploying standard pheromone traps and light traps, technicians can track pest population levels and when fewer male moths are caught the more likely the program is working.
