Accidentally disturbing a wasp nest can turn a routine garden task, outdoor gathering, or home maintenance job into a frightening emergency in seconds. Wasps defend their nest aggressively, and a sudden swarm can deliver multiple painful stings to anyone nearby. Knowing how to respond calmly and quickly is the difference between a minor incident and…

Few outdoor encounters are as jarring as the sudden buzzing swirl of wasps around a backyard picnic. Two of the most commonly confused—and feared—species in North America are the bald-faced hornet and the yellow jacket. Though they belong to the same family (Vespidae) and share many habits, they differ in appearance, nesting habits, colony size,…

Wasps are a familiar—and for many homeowners, unwelcome—part of Seattle’s spring and summer landscape. Knowing when wasps build nests in this region helps residents anticipate problems, identify active nests before they grow large, and decide the best times to take preventive measures or call a professional. Because wasp activity follows a predictable seasonal rhythm tied…

Few things disrupt outdoor life faster than the sudden, angry buzz of wasps. Unlike bees, many wasp species will aggressively defend a nest if disturbed, and nests hidden in eaves, wall cavities, attics, or underground can be hard to spot until someone wanders too close. Finding a hidden wasp nest early — before anyone gets…

Yellow jackets are small, fast-moving social wasps whose nests can be hidden in wall voids, attics, tree cavities, underground burrows and inside dense shrubs. Unlike honey bees, yellow jackets are carnivorous scavengers that become highly defensive when their nest is threatened; they can sting repeatedly and recruit colony mates with alarm pheromones. For these reasons,…

If you live in or visit Seattle, you’ll almost certainly encounter spiders — in gardens, basements, garages and occasionally inside homes. But the question, “Are there any spiders in Seattle you should never kill?” is more than a curiosity; it touches on safety, ecology, and common misconceptions. Most of the spiders you see in the…

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…
