Pest control in Kennewick
Local and licensed. From the Columbia River waterfront up to the south hills, we treat Kennewick homes on a seasonal plan — spiders, ants, wasps, mice and the fall invaders.
Common pests in Kennewick
Black Widows
Concentrated in warm, dry eastern Washington. We treat foundations, window wells, garages and clutter zones where they hide.
Ants
Odorous house ants, pavement ants and structure-damaging carpenter ants. Trails traced back to the colony.
Boxelder Bugs
Swarm sunny south walls every fall and slip inside through cracks. A perimeter barrier keeps them out.
Mice, Rats & Voles
Move indoors as it cools. Exclusion and monitoring, plus vole control for lawns and landscaping.

What Kennewick homes are up against
Kennewick stretches from the Columbia River up into the south hills, and the housing changes a lot along the way: older homes and crawl spaces near downtown and Kennewick Avenue, established neighborhoods around Westgate, and newer subdivisions in Southridge and Canyon Lakes that still back onto open ground.
That mix is why one Kennewick street can have a mouse problem while the next one fights black widows in the garage. We look at what your particular house is up against before we treat — the river, the slope, the age of the build, and what's growing along the foundation.
Near the river: moisture and the bugs that follow it
Homes close to Columbia Park and the waterfront see more moisture-loving pests — earwigs, silverfish and the spiders that feed on insects drawn to porch lights. We focus on the foundation line, window wells and exterior lights.
South hills: open ground on the edge of the yard
Newer homes in Southridge and around Canyon Lakes often border sagebrush or lots that haven't been built on yet. When it cools off in fall, mice and wolf spiders move from that open ground toward the warmest thing nearby — your house.
Older homes: crawl spaces and gaps
Older Kennewick homes tend to have crawl spaces, settled siding and gaps around pipes. Those are the black widow and mouse highways, so we check crawl-space vents, garage door seals and utility penetrations, not just the yard.
