Seattle’s damp climate plays a surprisingly large role in shaping the tiny ecosystems that exist just inside our walls. Relative humidity is one of the key environmental variables that determines where spiders can survive, grow, reproduce and build webs; and Seattle—with its ocean-moderated temperatures, frequent marine layers, and long, wet fall–winter season—creates indoor and outdoor…

Spiders are a natural and often beneficial part of the ecosystem around your home: they eat many nuisance insects and help keep pest populations in check. Still, many homeowners prefer to limit spider activity for comfort, aesthetic reasons, or concern about the occasional venomous species. When reducing spiders, the safest and most sustainable approach is…

You clear away a dusty web from the corner of your porch, feeling satisfied — only to find a new one there a few days later. This is a common, exasperating experience that makes it seem as if the spider is ignoring your efforts or deliberately tormenting you. In reality, a spider’s persistence is driven…

If you live in the Pacific Northwest and have seen more than a few webs around your eaves, crawlspaces or basement corners, you’ve likely wondered how long a professional spider treatment will actually last. The answer isn’t a single number — it depends on the kind of product used, where it’s applied, the species you’re…

If you’ve ever surprised a long-legged spider in a basement corner or along a ceiling seam, you’re not alone — two of the most commonly encountered species in homes are the giant house spider and the hobo spider. They look similar at a glance and both move fast, which fuels worry and misidentification. But despite…

As the days shorten and temperatures drop, many homeowners notice a flurry of new eight-legged visitors inside their houses. Fall is prime time for spiders to move indoors — not because they suddenly prefer tile over turf, but because your home offers exactly what they need: consistent warmth, protection from the elements, and a steady…

Seattle’s cool, wet climate makes basements and crawl spaces prime real estate for spiders. Dampness, sheltered voids, and an abundance of insect prey all contribute to steady spider activity in below-grade areas, and the region’s older homes often have vents, gaps and landscaping features that make ingress simple. While most spiders found in Seattle (cellar…

If you live in Seattle, you’ve probably noticed the same pattern every rainy season: spiders seem to turn up inside homes, apartments and garages in greater numbers. The Pacific Northwest’s long, wet autumn and winter — with frequent drizzle, persistent humidity and cool temperatures — creates outdoor conditions that aren’t ideal for many spider species….

Seattle’s damp, temperate climate and abundance of hiding places make it a comfortable environment for many kinds of spiders. For residents and visitors who spot an eight‑legged houseguest, the immediate question is often: which of these spiders are actually dangerous? The short answer is that the vast majority of spiders you’ll encounter in Seattle are…

Getting rid of an ant infestation can feel like a major victory—until the scouts start reappearing a few weeks later.
