If you live in King County, Washington, mosquitoes are more than a summertime nuisance — they’re a diverse group of insects with different habits, habitats and public‑health implications. Understanding which species are most common locally helps explain when and where you’re likely to be bitten, which diseases (if any) are a concern, and which control…

Every spring, Seattle residents start asking the same question: when will the mosquitoes return in force? In the Pacific Northwest’s mild, maritime climate the answer isn’t a single calendar date but a seasonal pattern driven by temperature, rainfall, and local breeding habitat. Mosquito activity in the Seattle area typically begins once nighttime and daytime temperatures…

When ants turn up inside a home, one of the first—and most important—questions for a homeowner is whether they’re dealing with nuisance foragers or a species that can damage wood. Two commonly confused groups are “moisture ants” (a loose term for several small species that prefer humid, decaying materials or soil) and carpenter ants (Camponotus…

Finding a sudden cloud of winged carpenter ants—or scattered winged bodies—inside your home in May can be alarming. Those flying ants are reproductive “alates” on mating flights, and their appearance often signals that a mature colony is nearby and that new colonies could be forming. Because carpenter ants excavate wood to create galleries, a swarm…

When you find ants trailing across your kitchen counter and spray cans or traps only seem to slow them down, it’s natural to wonder how long it will take to actually get rid of the colony once you’ve put out bait. The short answer is: it depends. Baiting works very differently from contact sprays —…

Just as the first warm days of spring coax buds from branches, they also stir insect life that’s been quiet all winter — and nowhere does that sudden activity feel more invasive than when you find a line of ants marching across your bathroom sink. Seeing these tiny intruders in a place you associate with…

Pavement ants—commonly the small, brown Tetramorium species often seen marching in thin lines across sidewalks—are especially well adapted to urban environments, and Seattle’s mix of wet winters, mild temperatures, and extensive paved surfaces makes driveways a particularly attractive landscape for them. Understanding how these ants choose nesting spots along driveways requires looking beyond the visible…

Odorous house ants (Tapinoma sessile) are one of the most common indoor invaders, and their movement patterns are usually the first clue that you have an infestation. Unlike some ants that forage in small scattered groups, odorous house ants typically form distinct, organized trails of individuals moving in single file between a food source and…

Ants are one of the most common indoor pests, turning up in kitchens, bathrooms and pantries where food and moisture are available. When homeowners spot a line of worker ants marching across a counter, the instinct is to act quickly — but the choice of treatment matters. Two widely used options are ant baits and…

It’s a frustrating, familiar scenario: you set out ant bait early in the season, the trails taper off and the piles of sugar vanish as if your bait is working—then midway through the season the ants are back, bold and numerous, and the bait sits untouched. Understanding why ant bait “stops working” halfway through the…
