Seattle’s rainy season has long been a defining feature of the city’s character — misty mornings, saturated soils, and the evergreen landscape at its most vivid. But that steady, seasonal dampness does more than paint the town a deeper green: it fundamentally changes the behavior and population dynamics of a wide range of pests. From…

Can you have effective pest control without using any chemicals at all? It’s a question that draws strong opinions—and for good reason. Concerns about human health, pets, pollinators, soil and water quality, and pesticide resistance have driven homeowners, schools, organic farmers and municipalities to explore non‑chemical strategies. At the same time, the idea of abandoning…

Pest pressure—the frequency and severity of pest activity around your home—affects comfort, health, and the integrity of your property. Ants, rodents, mosquitoes, ticks, termites and cockroaches don’t appear out of nowhere; their numbers and behavior are heavily influenced by the conditions you create outside. Thoughtful landscaping can dramatically reduce the attractiveness of your yard to…

Walk into any health-food store or scroll through an online marketplace and you’ll find shelves full of “natural” insect repellents and sprays promising to keep mosquitoes, ticks, ants and pantry pests away — all made with essential oils. The idea is appealing: fragrant plant extracts instead of synthetic chemicals. But the reality is mixed. Some…

A healthy garden is a miniature ecosystem: plants, soil, insects, birds and other wildlife interact in ways that produce flowers, fruit and the quiet satisfaction gardeners crave. Among those creatures, pollinators — bees, butterflies, hoverflies, moths and others — are especially important. They are responsible for the reproduction of many vegetables, fruits and ornamentals, and…

Seattle’s mild, rainy climate and lush, green landscapes make it a gardener’s dream — and a pest’s, too. Damp soil, shady corners, abundant organic matter and a backyard full of native shrubs and birdlife create ideal conditions for slugs and snails, aphids and earwigs, voles and moles, raccoons and even deer. For homeowners who want…

Biological control methods use living organisms or their natural products to reduce pest populations rather than relying on synthetic chemical pesticides. That includes introducing or encouraging predators (lady beetles, lacewings), parasitoids (tiny wasps that lay eggs in caterpillars or aphids), pathogens (bacteria such as Bacillus thuringiensis, fungi like Beauveria, or viruses that specifically target insects),…

Seattle’s cool, wet climate and its mix of urban and verdant spaces create a familiar roster of household pests: ants (especially odorous house ants and carpenter ants), cockroaches, spiders, fleas, silverfish, slugs, and occasional bed bug or tick problems. Homeowners and gardeners often reach for simple, low-toxicity solutions, and diatomaceous earth (DE) — a fine,…

Pest control has long been synonymous in the public mind with chemical sprays and blanket treatments. But decades of experience from agriculture, public health, and urban pest management have shown that routine heavy reliance on broad-spectrum pesticides is neither necessary nor sustainable. Integrated Pest Management (IPM) offers a smarter alternative: a science-based, site-specific decision framework…

Seattle’s famously damp, mild climate — long, cool rainy seasons and high humidity — is wonderful for Douglas firs and ferns, but it also makes pest control a different kind of challenge than in hot, dry regions. Many people in the Pacific Northwest turn to “natural” pest repellents to avoid synthetic chemicals and protect garden…
