I live on the Snohomish County side of Bothell. Do you serve both sides?

Yes. We cover Bothell on both sides of the county line, from downtown and Westhill in the south to Canyon Park and the Thrasher's Corner area up north. The service, timing and warranty are the same either way. What changes the job is the house and the terrain around it, not the county on your tax bill.

My backyard backs onto a protected greenbelt. Can you treat it?

We treat your property, not the protected area behind it, and that still works well. We focus on the foundation, the fence line and the side of the house facing the trees, treat ant colonies on your side, and seal entry points so whatever lives in the greenbelt stays out there. Moving firewood and yard debris away from the house helps too.

There is construction near my neighborhood. Should I expect mice?

It is common for rodents to move when nearby land is cleared, because their shelter and food disappear overnight. You won't necessarily get them, but it is a good time to have entry points checked and sealed before they come looking. Exterior bait stations catch the ones that show up before they find a gap.

How quickly can you get to Bothell?

Someone will be at your door within 48 hours. Bothell is 35 min south of Lake Stevens HQ, and you get a text about 30 minutes before the truck arrives. Stinging-insect calls get priority on the schedule.

Is the treatment safe around kids and pets?

Yes. We use products rated for occupied homes and apply them where pests travel, not across your living space. The technician walks you through what goes down and where before anything is treated. If you keep bees, chickens or a vegetable garden, tell us and we work around them.

Pest control in Bothell, WA

Bothell is split by the King and Snohomish county line. Downtown and the Sammamish River sit on the King County side, while Canyon Park, Queensborough and the neighborhoods up toward Thrasher's Corner are in Snohomish County. North Creek runs down through the middle of it all, from the business parks to the river.

The county line doesn't matter to ants or mice, and we serve both sides. What matters is the terrain. Pest control in Bothell means dealing with North Creek's wetlands and greenbelts, steep wooded hillsides, mid-century homes near downtown and newer construction on the north end, all within a few miles of each other.

Ant Control in Bothell

Ants along Bothell's greenbelts and North Creek wetlands

Bothell holds a lot of protected green space: the North Creek wetlands and forest, wooded ravines on the hillsides, and native growth tracts behind many subdivisions. That ground is full of stumps, logs and damp soil, the natural home of carpenter ants. Homes backing onto it get foragers crossing the lawn in spring, and a colony that finds damp wood in a deck, sill or window frame will set up a satellite nest in the house.

We start by identifying the species. Carpenter ants mean tracing the trail back to the parent nest, often in a stump or tree outside, and treating it along with any satellites in the structure. Odorous house ants in the kitchen get baited rather than sprayed. Watch for big black ants indoors from March through May, and coarse sawdust near window frames or along the garage wall.

Spider Control in Bothell

Fall spiders in homes backing onto Bothell's wooded hillsides

Much of the city is built into hills with native trees left between lots, and that tree cover holds a lot of insects and a lot of spiders. Giant house spiders and hobo spiders wander in late summer and fall looking for mates, and they get in through garage doors, window wells and gaps at the foundation, especially on homes with daylight basements facing the woods.

We treat entry points around the foundation, garage and lower-floor windows, and clear webs and egg sacs from the eaves, soffits and siding. Switching porch lights off, or to yellow bulbs, cuts down the insects that draw spiders to the house. Watch for large brown spiders running along the base of the walls downstairs from late August on.

Rodent Control in Bothell

Rodents displaced by construction along Bothell's growth corridors

Canyon Park and the North Creek corridor keep adding office, lab and housing space, and the unincorporated areas around Thrasher's Corner are still filling in. Clearing and grading push out the mice and rats that lived in the brush. Older homes near downtown and on Westhill, many from the middle of the last century, have more gaps from decades of settling and give those displaced rodents an easy way in.

Rodent control in Bothell begins with exclusion. We seal gaps a quarter inch and up with hardware cloth, sheet metal, mortar or copper mesh, then place tamper-resistant bait stations outside and snap traps inside, with return visits to check and remove them. Listen for scratching in the ceiling at night, and check the garage and crawl space for droppings along the walls.

What changes the job here

Mid-century homes, hillside lots and new construction in Bothell

Westhill grew as a mid-century expansion west of downtown, and much of the older housing around the core dates from the 1950s through the 1970s: ramblers, split-levels and daylight basements cut into slopes. Those homes have more wood near the soil, older vent screens and settling gaps, so exclusion and a look at the crawl space or lower walls come first.

North of the county line, Canyon Park, Queensborough and the Thrasher's Corner area are mostly subdivisions from the 1980s onward, with townhomes and apartments near the business parks. Newer homes have fewer gaps but often back onto native growth protection areas, so pressure comes from behind the fence rather than through the walls. Many sit in HOAs, so we keep stations discreet and the work clean.

Across Bothell

Bothell neighborhoods and what they deal with

Downtown Bothell and the Sammamish River: Low ground along the river and trail corridor brings mosquitoes in summer and rats in the riverbank brush.
Westhill: Mid-century homes on the hill west of downtown have the settling gaps and older crawl spaces that let mice in.
Canyon Park: Business parks, apartments and homes around the North Creek wetlands give ants and rodents a lot of edge habitat.
Queensborough: Homes near Swamp Creek and its wooded buffers deal with carpenter ants and spiders coming out of the trees.
Thrasher's Corner: Ongoing development on the north edge pushes displaced mice toward the surrounding neighborhoods.
Maywood Hill: Steep, heavily treed lots east of downtown mean wasps in the eaves and spiders on the lower floors.

Through the year

The Bothell pest year, season by season

Spring: Carpenter ants come out of the North Creek and hillside greenbelts in March and April and start scouting decks and sills.
Summer: Yellow jackets build in ground holes and wall voids on wooded lots, and the river flats downtown get mosquitoes.
Fall: Spiders move into lower floors and garages from late August, and mice follow once the October rain arrives.
Winter: Rodents that got in during fall show up in attics and crawl spaces, and nearby construction can push new ones in any month.
