About our service
Pest control for Washington, IL
Washington, Illinois has a population of roughly 15,900, and its long list of parks tells you a lot about where pests come from. Harry LaHood Park, Westgate Park, Candlewood Park, Sweitzer Park, Washington Park and Babcook Field all offer grass, trees and shade, and homes near that kind of ground tend to get a steady stream of ants, spiders and wandering insects looking for a way inside.
Natural Pest Solutions offers ant treatment, rodent control, termite control, cockroach control and pest inspection for Washington homes and businesses. Our natural pest control options rely on non-toxic, low-impact products that are safe around kids and pets. You will never be asked to sign a long-term contract, and a free quote is where every job begins.

Know your pests
Pests we treat around Washington
Pests in Washington
What we deal with most around Washington, IL
Most Washington calls fall into a familiar handful. Mice and rodents look for warmth in garages, basements and attic corners as soon as nights cool off. Carpenter ants show up in wet wood around bathrooms, roof lines and old stumps, and termites feed out of sight in wood that touches soil. Cockroaches turn up in kitchens and utility rooms, and spiders settle in sheds, window wells and porch corners.
The freezing nights add up here, with about 134 a year at or below 32 degrees, so autumn is when boxelder bugs and stink bugs pile up on sun-warmed siding and look for cracks. In warm months, wasps start nests under eaves and playground equipment, and mosquitoes and ticks follow the moisture and tall grass around open green areas.
Weather and pests
How Washington's weather affects pest activity
Weather in Washington swings between hot summers and hard winters. July highs average about 86 degrees and January lows about 17. Expect around 37 inches of precipitation and about 22 inches of snow in a typical year, with May the wettest month at roughly 4.8 inches. Those numbers are 1991-2020 NOAA climate normals from a nearby weather station and work best as a guide, not a forecast.
About 24 days a year reach 90 degrees or higher. Those hot stretches are when ant trails thicken, wasp nests grow and mosquitoes multiply in any standing water, from clogged gutters to tarps and birdbaths. The spring rain that peaks in May also soaks the soil around foundations, which is the kind of dampness that termites and carpenter ants like best.
Timing matters more than anything else. Late winter is a good moment to look for rodent signs, early spring suits exterior barrier work, midsummer is for water control and wasp checks, and early fall is the window for sealing gaps before the first cold snap. We can help you set that schedule around your particular house.
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. A yearly inspection costs little next to the cost of repairs. 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
A little standing water is all it takes for mosquitoes to breed in Washington. 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.
