Precision Pest Control works houses and apartment buildings across Seattle, from older craftsman homes in neighborhoods like Ballard and Wallingford to newer construction near South Lake Union. Most calls we get from late summer into fall involve something stinging, not something crawling. That single fact changes how we schedule and staff a season here more than anything else.


Stinging flying insects fill our schedule from August through October, mostly yellowjackets nesting in wall voids, attic eaves, and abandoned rodent burrows in the yard. We also handle spiders in damp crawlspaces and window wells, carpenter ants working through wet or rotting framing near gutters and downspouts, and termites in older foundations closer to the water. Rats move through cedar hedges and blackberry thickets between properties, centipedes turn up in basements after heavy rain, and ticks ride in on pets that spend time in parks with tall grass or brush.
Yellowjackets are the pest that defines a Seattle season more than any other, and the reason comes down to timing and geography. Colonies that started small in a rockery or an old vole tunnel in June spend a mild, wet spring building numbers slowly, then expand fast once the dry stretch of August arrives and natural food sources thin out. That's when foraging workers show up at picnics in parks like Volunteer or Gas Works, and when nests hidden behind a Ballard bungalow's siding finally get noticed, usually because someone got stung mowing near a hedge. A colony that size doesn't respond to spraying the entrance, and it keeps producing workers until a hard frost, which here often arrives later than it does further inland.
Everything else on the list matters, but plays a smaller role. Spiders and centipedes track the region's damp crawlspaces and basements more than any single hot spot. Carpenter ants follow moisture into framing near leaking gutters, common in a city with this much rain and this much older housing stock. Termites turn up mostly in foundations near the water, in neighborhoods closer to Lake Washington or the Duwamish, where soil stays wetter longer into the season. Rats move along green corridors like blackberry thickets and cedar hedges that connect one yard to the next, and ticks usually arrive by way of a dog that spent an afternoon in tall grass at a park nearby.
