Pest Control & Termite Control in Modesto, CA

Modesto’s position at the heart of the Valley means pest pressure doesn’t follow a tidy seasonal schedule. Warm, dry summers push rodents and spiders indoors, while mild winters give ant colonies the chance to stay active longer than homeowners expect. We serve Modesto, CA, as well as Ceres, CA, Salida, CA, Empire, CA, and Keyes, CA. Our residential pest control services cover the pests common to Central Valley homes and businesses: Whether ants eat crumbs in your kitchen or rats enter your attic, Dewey Pest Control has you covered. Pests we treat include:

• Spiders
• Beetles
• Earwigs
• Gophers
• Mosquitoes
• Bees
• Silverfish
• Sow bugs
• Wasps

Commercial properties in Modesto’s industrial and food-processing corridors face a different pest profile than a single-family home. Warehouses near the Beard Industrial area deal primarily with rodents and stored-product pests. Our commercial pest control services place monitoring stations on a documented schedule, track activity trends over time, and treat sanitation and exclusion as the primary line of defense. Loading docks and overhead door gaps are the pressure points that need the most consistent attention.

Restaurants and food-service operations face stricter requirements around cockroach and fly activity, and service records may be provided to support audit and food-safety documentation. Our residential plans cover everything from single-family homes to multi-unit properties across Modesto, CA, and the surrounding communities.

Subterranean termites work quietly, and most infestations are already well established by the time a homeowner notices mud tubes along the foundation or finds discarded wings near a windowsill. Hollow-sounding wood is another sign worth acting on immediately. Our termite control treatment uses a perimeter barrier approach that targets activity at the foundation level, paired with bait station monitoring that tracks pressure over time rather than offering a one-time fix.

Annual inspections are the most cost-effective part of any prevention plan. Older properties in La Loma can carry decades of deferred wood-to-soil contact that gives termites a foothold, and the neighborhood’s mature tree canopy and proximity to the Tuolumne River keep soil moisture high against the foundation. For established drywood infestations, our services may include whole-home fumigation or heat treatment, depending on what the inspection finds.

Unexplained bites or small rust-colored stains on bedding are reasons to check whether bed bugs are present and how far they’ve spread. Our technicians conduct a methodical inspection of mattress seams, box springs, headboards, furniture joints, and baseboards, looking for live insects, shed skins, and staining that maps the extent of the infestation room by room. Our bed bug exterminator services give you a clear picture of what was found and where.

Bed bugs spread quickly between rooms because they hitchhike on clothing, luggage, and furniture. Preparing the treatment area properly, laundering bedding and clearing clutter from around the bed frame, improves outcomes and helps the treatment reach all harborage points.

A spider in the garage corner is usually there because the garage also has the insects it feeds on. Clear the webs, close the gaps along the door frame and foundation, and reduce the insect population inside, and spiders have less reason to stay. Garages, ceiling corners, and the areas around exterior lighting tend to accumulate both webs and the bugs that attract them.

Cockroaches, fleas, and flies each require a different approach, though all benefit from the same foundation: identifying where they’re coming from, treating those sources, and reducing the conditions that attract them. Our cockroach control services target harborage areas and entry points, flea treatment reaches the carpet and yard zones where immature stages develop, and fly control starts with the breeding source rather than the adults you can see. Our licensed technicians apply products according to label directions and explain any preparation or reentry precautions before treatment.

A line of ants crossing the kitchen counter is the visible part of a much larger problem somewhere outside the wall. Spraying the trail kills the scouts, but the colony simply sends more. Solving it means identifying the species, treating the colony at its source, and sealing the entry points those scouts are using. Odorous house ants, pavement ants, and Argentine ants are the most common indoor offenders in Modesto, CA, and each responds to a different treatment approach. Carpenter ants tunnel into wood, making them a structural concern rather than just a nuisance, and they require targeted inspection of damaged or water-affected wood.

Trimming vegetation away from exterior walls and sealing gaps around pipes, utility lines, and door frames cuts off the routes ants use to enter. Our ant control services include recurring visits that prevent colonies from re-establishing once the initial treatment is complete, which matters in a climate where ant activity can persist well into fall.

Mosquito season in the Valley starts with standing water. An untended pool, a clogged gutter, a saucer under a planter, or low ground that holds irrigation runoff is all it takes. Our mosquito control services target those breeding sites along with the shaded resting spots adults use during the heat of the day.

Ticks gather in leaf litter, unmowed grass, and shaded perimeter zones where pets and people pass through regularly. Trimming back overgrowth, clearing leaf debris from fence lines, and keeping play areas in open spots reduce the habitat ticks need to thrive. Checking pets after time outdoors and keeping their rest areas clear of debris reduces how many ticks make it inside. For pet protection products, your veterinarian is the right resource, and our focus stays on the yard and perimeter where exposure happens first.

Wasp and hornet colonies grow through summer and reach peak size by late August and September, which is also when they’re most defensive. Our wasp and bee removal services include locating nests on the structure, assessing the species and activity level, and removing the nest with protective equipment and careful timing to reduce defensive swarming.

After removal, sealing the eaves, vents, and wall voids where nests formed discourages rebuilding the following season. Active wasp and hornet nests are not a DIY job, particularly when they’re inside a wall void where the full colony size isn’t visible from outside.

Rodent activity tends to surface once cooler months arrive and mice or rats start looking for indoor shelter. In established areas like the College Area, where early twentieth-century homes sit along Dry Creek and the Virginia Corridor, that shelter is easier to find than most owners expect.

Droppings along baseboards, gnaw marks on food packaging or wiring, and scratching sounds in walls or the attic indicate activity is already underway. A mouse can pass through a gap barely a quarter-inch wide, so the roofline, foundation, utility penetrations, garage door corners, and dryer vents all need to be addressed. Our rodent exterminator services treat exclusion as the first step, using hardware cloth, steel wool, and appropriate sealants to close those gaps before trapping begins.

Trapping is the cleanup step after entry points are sealed, not a standalone solution. Gnawed wiring is a fire risk, and droppings and urine contaminate the surfaces they touch, so the mess rodents leave matters as much as the animals themselves.
