Local pest control help is one call away.
Pest Control Services Nationwide Pest Control Services Nationwide The Cascade rain shadow splits Washington into two pest realities. West of the mountains, carpenter ants chew through wet siding and crawl space joists in Seattle and Tacoma. Brown marmorated stink bugs swarm windows in Vancouver every fall. East of the Cascades, deer mice and pack rats push toward irrigated yards in Spokane and the Tri-Cities. Your local provider already knows which problems hit homes on your side of the range.

Western Washington gets over 35 inches of rain a year, and that constant moisture drives almost every pest problem in the state. Wet siding, soaked sheathing, and shaded crawl spaces give wood-destroying insects everything they need. Mild winters mean rodents and ants barely slow down. East of the Cascades the picture flips, with dry summers pushing rats and spiders toward watered lawns and outbuildings.
Most Washington homes need treatment plans built around moisture, not just pest species. A provider who works your area knows whether your problem is a wet crawl space, a roof tie-in, or a yard layout, and can pick a treatment that holds up through a Pacific Northwest winter.

Trusted by Washington homeowners to find the right provider.
Explore pest control services offered by Washington providers, from carpenter ant treatments and rodent control to moisture-related structural protection.
Mild Washington winters keep carpenter ants, spiders, and rodents active most of the year, so most homes need ongoing coverage rather than a one-time spray.
What to expect: a walkthrough of your home inside and out, species-specific treatment, and a return visit window if anything bounces back.
Learn MoreBed bugs spread quickly through Seattle apartments and Bellingham student housing, and heat treatment kills every life stage in one pass, including eggs that sprays miss.
What to expect: prep instructions a few days ahead, controlled heat above 120°F for several hours, and monitoring traps to confirm it worked.
Learn MoreWhen carpenter ant or dampwood termite damage runs deep through framing in an older PNW home, fumigation reaches galleries that spot treatments cannot.
What to expect: a prep checklist, a tarp tent over the structure, two to three nights elsewhere, and an all-clear inspection on return.
Learn MorePersistent rain rots out vent screens and crawl space hatches, opening the same gaps that let rats and stink bugs in year after year on Puget Sound homes.
What to expect: a foundation-to-roofline inspection, sealing of identified entry points, and a written summary of what was found and fixed.
Learn MoreMany Washington homeowners want lower-impact options for pets, kids, and a yard that drains into Puget Sound. Providers can lead with EPA-registered botanicals, traps, and exclusion before stronger products.
What to expect: inspection, low-impact product selection where possible, and a prevention plan so you don't end up needing repeats.
Learn MoreLong wet shoulder seasons in Washington wash exterior treatments off faster than in drier states, so quarterly barrier service is what actually holds spiders and ants at bay.
What to expect: exterior application around foundation and eaves, removal of accessible nests, and a quarterly or seasonal schedule depending on pressure.

Real outcomes for Washington homeowners we connected with a local pest pro.
"Bathroom ant entries closed off."
Seattle's rain meant our bathroom was constantly damp, and ants took notice. The tech treated the entry points and explained how ventilation improvements would reduce future activity. The combination of treatment and moisture control worked.

"Crawl space vents sealed against rats."
Rats had found an opening in our crawl space vent and were getting into the walls. The pro secured the vents, sealed the gaps, and set up a removal plan. The problem was resolved within a couple of weeks.
"Window sills repaired and ant-free."
The constant rain had softened our window sills and carpenter ants moved in. The tech treated the colony and explained how replacing the damaged wood prevents reinfestation. The repair and treatment together solved it.
"Siding re-sealed and carpenter ants treated."
Rain-soaked siding attracted carpenter ants. The provider treated the colony and recommended re-painting and caulking. Keeping siding sealed prevents moisture infiltration.
"Crawl space vents screened and mice cleared."
Faint scratching under the floorboards in our bedroom at night, every night. Drove my husband crazy. The inspector pulled back the crawl space hatch and showed me how the original vent screens had rusted out and mice were just walking right in. He installed proper hardware cloth on every vent and sealed two pipe penetrations. The scratching stopped within a week.
"Travel bed bugs cleared with one visit."
Three nights into being home from a conference in Seattle, I was waking up itchy. Pulled the sheets back at three in the morning and saw them along the box spring tape. Booked the heat treatment that morning. The crew was professional, the bedroom hit temperature for the full window, and we have been clear ever since. I now keep a hard-shell suitcase that lives in the garage.
"Garage cleared and door gaps sealed."
Walked into the garage one morning, hit a web at face height, then noticed every corner had its own. I could not park the car without driving through them. The tech treated the whole space, sealed gaps around the garage door corners where they were coming in, and recommended we get the kids' bikes and gear off the floor. Cleared out two trunk loads of clutter. Garage is finally usable.
"Barn rafters cleared of wasp nests."
Walked into the barn one July morning and saw at least four softball-sized nests up in the rafters. I quietly walked right back out. The crew suited up and took every nest down in one visit, then treated the wood. We are doing a preventive April spray every year now to stop queens from building. Two summers running the barn has been clear.
"Drip irrigation route to the house cut off."
I could not figure out why ants were appearing under the dishwasher when I had cleaned everything. The tech walked the perimeter and immediately spotted it: a drip irrigation line running right up against the foundation, with a constant slow trickle. Ants were following the moisture trail. We rerouted the drip lines, treated the perimeter, and sealed the entry point. Problem solved.
"Mid-renovation termites treated on the spot."
We opened up the wall between the kitchen and the living room and the bottom plate basically fell apart. Pacific Northwest moisture had been doing its thing for years apparently. The crew came out same week and treated all the exposed framing plus the slab edge. The contractor was patient about the delay. Monitoring stations are around the foundation now.
"Condo cleared and shared walls sealed."
Started seeing a roach or two at night in the kitchen. I have lived here twelve years without a single one, so I knew something had changed. Turns out a new tenant moved in next door. The tech treated with gel bait, sealed every penetration along the shared wall, and the activity stopped within ten days. The HOA finally agreed to a building-wide treatment, which is the real fix.
"Exterior sealed and stink bugs reduced."
Stink bugs gathered on the warm side of the house each fall. The provider sealed gaps and treated the exterior. The following autumn showed dramatic improvement.
"Yard comfort restored beside the creek."
Bought the place because of the creek out back. Quickly learned why the previous owners barely used the deck. The mosquitoes started at dusk and did not quit. The crew treated the yard perimeter and the brush line near the creek. They mentioned my standing rain barrels needed mesh tops too, which I had not thought about. Big improvement, especially in the evenings.
"Compost bin secured and crawl space sealed."
Every morning the compost bin was flipped on its side, lid yanked off, and the contents strewn across the patio. I could hear them most nights too. The wildlife specialist recommended a metal-latched compost bin and showed me a crawl space vent they had been using for shelter. We upgraded the bin, sealed the vent. Both changes together ended the nightly raids.

Washington homeowners commonly deal with moisture ants, carpenter ants, rats, stink bugs, and yellow jackets. The wet western side of the state sees heavy ant and rodent activity, while eastern Washington's drier climate brings more spider and wasp challenges. Your matched provider will identify the specific pest and recommend the right approach.
The Pacific Northwest's wet winters and mild summers create persistent moisture in wood framing, decks, and rooflines across western Washington. Carpenter ants tunnel through damp wood to build satellite colonies, and damage can accumulate over several seasons.
Annual inspections of crawl spaces, decks, and eaves, combined with fixing moisture sources, usually produce much better long-term results than spraying alone.
Norway rats and house mice infiltrate homes through crawl space vents, dryer openings, and foundation gaps throughout the Puget Sound corridor. The region's mild climate keeps rodent populations active year-round.
Exterior exclusion work focused on crawl space vents, overhead doors, and utility penetrations typically produces better long-term results than interior-only treatments.
Hobo spiders build funnel webs in basements, window wells, and ground-level storage areas throughout Washington. They're most commonly encountered in the fall when males wander in search of mates.
Sealing foundation gaps, reducing clutter in storage areas, and having providers apply targeted treatments to basement and garage perimeters are the common control approaches.
