If you wake up congested, sneezing, or with itchy eyes and skin on a regular basis, your bedroom could be the source of the problem—even if you can’t see anything out of the ordinary. Dust mites are microscopic relatives of spiders that live in warm, humid indoor environments and feed on flakes of human skin….

Mites are tiny arachnids—close relatives of ticks and spiders—that are so small they usually go unnoticed until they affect our health, comfort, or possessions. Many species have adapted to live alongside people in homes, feeding on organic debris such as shed skin cells, pantry items, or even the blood of birds, rodents, pets and humans….

Seattle’s mild, wet climate and abundant green spaces make it a pleasant place for people—and for wildlife. That includes snakes. While most snake sightings inside the city are of harmless garter snakes, and venomous species are extremely uncommon within Seattle proper, homeowners still have good reasons to prevent snakes from taking up residence. Snakes can…

Chemical pesticides and antibiotics have been indispensable tools in agriculture, public health and stored-product protection, dramatically reducing crop losses and controlling disease vectors. Yet their repeated use has a built-in Achilles’ heel: pests—whether insects, weeds, fungi or microbes—can and do become less susceptible over time. Understanding how resistance develops is essential for designing strategies that…

Home gardeners and homeowners often turn to natural, readily available remedies to solve the nuisance of moles tunneling across lawns and flowerbeds. Peppermint oil is one of the most popular of these DIY solutions: it’s inexpensive, easy to obtain, and its strong aroma is assumed to drive animals away. But while peppermint oil can sometimes…

When gardeners and land managers in the Pacific Northwest find raised ridges and cratered lawns, one of the first questions is deceptively simple: how deep do moles actually burrow? The answer matters for more than just cosmetic repairs. Burrow depth determines how much root damage moles can cause, how resilient their tunnels are to weather,…

Few things are more frustrating for a gardener or homeowner than waking to see neat ridges and collapsed lawn from a network of mole tunnels. A “mole wall” — a physical barrier built to keep moles out of beds, lawns, or around foundations — can be a highly effective long‑term defense when planned and installed…

Cockroaches are among the most persistent indoor pests, and roach traps are one of the most common tools homeowners and professionals use to detect and reduce their numbers. A good introduction to how these traps work requires understanding both cockroach behavior and the types of traps available. Cockroaches are nocturnal, opportunistic foragers attracted to food,…

Cockroaches are more than an unpleasant sight in the kitchen — for renters in Seattle they represent a real and underappreciated public-health concern. These resilient insects thrive in dense, moisture-prone environments and can establish persistent populations in multi-unit buildings, older homes, and anywhere food, warmth, and hiding places are available. Because many Seattle renters live…

Seattle’s temperate, maritime climate has long shaped the region’s urban ecology and the seasonal rhythms of household pests. But as global temperatures climb and precipitation patterns shift, the dynamics that govern pest survival, reproduction and movement are changing too. For Seattle—where winters are traditionally mild and summers cool—projected warming, intensified winter rain events, drier summers…
