Pests we treat around Washington
Pests in Washington
What we deal with most around Washington, MO
Near the riverfront and in the shady residential blocks, mosquitoes and ticks are common complaints from late spring on. Carpenter ants favor damp wood in old porches and fence posts, and termites feed quietly around foundations. Indoors, spiders, cockroaches and mice are the usual suspects, with stink bugs and boxelder bugs collecting on sunny walls when the days cool off.
Washington sees about 116 nights a year at or below freezing, one of the longer cold seasons of any city in this batch, so the drive indoors starts early and lasts a long while. Warm spells still arrive, with about 40 days a year at 90 degrees or higher, and those are when ants and flies peak. A plan that covers both ends of the year works better than treating whatever shows up.
Weather and pests
How Washington's weather affects pest activity
Washington's figures are 1991-2020 NOAA climate normals from a nearby weather station, offered as a guide and not a forecast. July highs average about 88 degrees, while January lows average around 20. Total precipitation runs about 44 inches a year, with roughly 8 inches of snow, and May is the wettest month at about 5.3 inches.
Those 116 freezing nights shape the calendar. Rodents and overwintering insects often start scouting for shelter well before the first hard freeze, and by December they may already be living in an attic, crawl space or wall void. Sealing gaps in the fall is far easier than tracing scratching sounds in January. Pay special attention to utility lines, chimney flashing and the seams of garage doors.
When spring arrives, the wet weeks of April and May feed mosquito breeding and wake up ants. Clearing gutters, tipping out containers and trimming vegetation off the siding takes away shelter and moisture. Homes close to the river or thick tree cover may want an earlier start on treatment. A technician can tailor a schedule so you are not guessing about what to do each season.
How we fix it
Pest control services in Washington
Ant treatment in Washington
Ants are among the most common calls we get in Washington, from sugar ants in kitchens to carpenter ants in damp or damaged wood. Activity climbs quickly once spring temperatures arrive. We find the trails and the nest, treat where the colony lives and follow up so they do not simply return.
Rodent control in Washington
Mice and rats look for food, warmth and shelter, and Washington buildings offer plenty of all three. With a long cold season, the pressure builds every fall. Our exclusion-based approach combines inspection, sealing entry points, trapping and monitoring, so you fix the reason rodents got in, not only the rodents you can see.
Termite control in Washington
Termites are a quiet threat because damage often goes unnoticed for years. Regular moisture around foundations makes regular checks especially worthwhile. We inspect for mud tubes, damaged wood and moisture problems, then treat with a plan matched to how your Washington home is built.
Cockroach control in Washington
Cockroaches are hard to get rid of with store-bought sprays. We locate the hiding places, treat cracks, crevices and voids, and use monitoring so we know the treatment worked. It is a common request in Washington apartments, restaurants and older homes alike.
Spider control in Washington
Most spiders are harmless, but nobody wants webs around the door or a spider in the basement. We remove webs and egg sacs, treat the perimeter and reduce the insects that spiders feed on, which keeps them from coming back.
Mosquito control in Washington
Washington's wet weather makes mosquitoes a real nuisance. We treat resting areas in your yard, help you find and remove breeding sites and schedule visits through the warm season so you can use your yard again.
