My yard backs onto the Sammamish River. Can you actually cut down the mosquitoes?

You won't get to zero next to a river, because the river is outside your fence. What we can do is remove the breeding water on your property, treat water that can't be drained, and put a barrier on the shaded plants where adults rest. Most river-lot yards become usable in the evening again with that approach and regular visits from May through August.

I live near the Burke-Gilman Trail. Is that why I have rats?

It is a likely part of it. The trail corridor, the brush along it and the river banks give rats cover to travel between yards. That's why we seal the house instead of only trapping. Once the gaps are closed, the rats outside have no easy way in, and the exterior bait stations handle the ones working the yard.

Does a daylight basement mean I don't need crawl space work?

Not usually. Many Kenmore hillside homes have a daylight basement on the downhill side and a crawl space under the rest of the house. We check both. The crawl space portion is often where the moisture, the torn barrier and the rodent activity are, even when the finished basement looks fine.

How quickly can you get to Kenmore?

Someone will be at your door within 48 hours. Kenmore is 45 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 Kenmore, WA

Kenmore sits where the Sammamish River empties into the top of Lake Washington, and Swamp Creek joins the river on its way through town. That much slow water, plus the wetland edges along the river, sets the tone for pest control in Kenmore: mosquitoes in summer, rodents working the shoreline and trail corridors, and damp crawl spaces under the hillside homes.

Drive ten minutes up the hill to Bothell or over to Shoreline and the picture shifts toward dry-ground problems. Here, a lot of the job is about moisture. Where the water sits, what it feeds, and how it gets under your house decide what we treat first.

Mosquito Control in Kenmore

Mosquitoes along Kenmore's river and lakeshore

Mosquitoes need still water to breed, and Kenmore has plenty of it: the slow lower Sammamish River, the marshy margins near Log Boom Park, Swamp Creek's backwaters and every low spot in a shaded yard that holds rain into June. Homes backing onto the river or the wetland edges get the heaviest pressure, but a clogged gutter or a forgotten kiddie pool on the hill can breed a yard's worth on its own.

We start by finding and draining standing water on your property, then use larvicide where the water can't be removed, like a pond or a low drainage swale. The barrier treatment goes on the shaded leaves and dense shrubs where adults rest during the day, not the open lawn. Visits run heavier from May through August. Between visits, tip anything that holds water after a rain, including saucers, tarps and toys.

Rodent Control in Kenmore

Rats and mice on Kenmore's waterfront and trail corridors

The Burke-Gilman Trail, the river banks and the blackberry thickets along them give rats long, protected runs right behind the houses. Norway rats burrow along foundations and bulkheads near the water, while roof rats use the tall conifers on the Inglewood slopes to reach rooflines. Either way, a crawl space vent with a broken screen is an open door.

Rodent control in Kenmore starts with exclusion. We seal every gap a quarter inch and larger with hardware cloth, sheet metal, mortar or copper mesh, set tamper-resistant bait stations outside and snap traps inside, then come back to check and clear them. Watch for droppings along the crawl space sill, gnawed vent screens and scratching in the walls at night once the fall rains start.

Crawl Space & Vapor Barrier in Kenmore

Damp crawl spaces under Kenmore's hillside homes

Much of Kenmore was built from the 1950s through the 1970s on slopes that shed water toward the lake. Groundwater and runoff move under those houses, and the original plastic in the crawl space has usually torn, shifted or disappeared. A wet crawl space rots sill plates, invites carpenter ants and gives rodents a quiet place to nest.

We haul out the old barrier and any insulation that rodents have soiled, rodent-proof the vents and gaps, then lay a new 6-mil vapor barrier across the ground. A fresh, intact barrier also makes the next inspection easier, because droppings and trails stand out on clean plastic. Signs you need it: a musty smell in the house, insulation hanging from the joists, standing water or visible droppings when you lift the access hatch.

From the call to the follow-up

Hiring a Kenmore exterminator

When you call us as your Kenmore exterminator, we ask where the house sits relative to the lake, the river and the slope, because that tells us a lot before we arrive. Someone is out within 48 hours, and you get a text about 30 minutes ahead. The tech walks the yard, the foundation and the crawl space, explains what is going on and treats that day. If the problem comes back inside the warranty window, the re-treatment costs you nothing.

What changes the job here

Lakefront, hillside and mid-century homes in Kenmore

Most Kenmore homes are 1950s to 1970s ramblers and split-levels on wooded lots, many on a slope with a daylight basement on the low side and a crawl space under the rest. That mix means we check two different foundations on one house. Newer infill homes and townhomes have gone in closer to the SR 522 corridor, and their gaps tend to be at utility penetrations and garage door seals.

Waterfront and near-water lots in Arrowhead and along the shoreline bring bulkheads, docks and dense landscaping that rodents use as cover. Big firs and cedars over the roof drop needles into gutters, which hold water for mosquitoes and keep the roof edge damp.

Across Kenmore

Kenmore neighborhoods and what they deal with

Inglewood: Winding wooded streets and tall evergreens mean branches over rooflines, so roof rats and carpenter ants are the main concern.
Moorlands: Older homes mixed with new construction, so we see failed original crawl space barriers next door to fresh utility gaps.
Arrowhead: Lake-side lots in southern Kenmore, with some of the oldest homes in town, carry rodent pressure along the shoreline and moisture under the floors.
Uplake: Lake-view homes near the Burke-Gilman Trail and Log Boom Park sit close to the wetter shoreline where mosquitoes breed.
Saint Edward State Park edge: Homes bordering the park's forest back onto a large wooded area that supplies rodents and ants to the nearest foundations.

Through the year

The Kenmore pest year, season by season

Spring: Carpenter ants swarm out of damp wood on warm April and May days, and the river bottoms start holding the water mosquitoes breed in.
Summer: Mosquito pressure peaks near the Sammamish River and lakeshore, and yellowjackets build in the shrubs and wall voids.
Fall: The first steady rains push rats off the river banks and trail edges toward crawl spaces and garages.
Winter: Rodents settle into crawl spaces and attics, and it is the right season to replace a failed vapor barrier before spring groundwater.
