Spider mites are tiny arachnids, barely visible to the naked eye, that feed by piercing plant cells and sucking out the contents. On houseplants they cause characteristic stippling, pale or bronzed leaves, fine webbing and, in severe cases, leaf drop. While these pests can appear any time of year, many Seattle houseplant owners notice them…

Spring bloom is the most critical and vulnerable time in the life of a fruit tree. In Seattle’s cool, maritime climate—characterized by damp, mild springs—blossoms and newly emerging leaves are especially susceptible to both insect pests and disease. Damage during bloom doesn’t just mar appearance: anything that chews, sucks, or infects flowers can directly reduce…

Late spring in Seattle is an exciting time for vegetable gardeners: the soil has warmed enough to set out hardy seedlings, long daylight hours speed growth, and the promise of summer harvests feels close. That same mild, moist climate that makes the Pacific Northwest ideal for many cool-season crops is also perfect for a handful…

Aphids are one of the most persistent pests in Pacific Northwest gardens: they reproduce quickly on the tender new growth of vegetables, ornamentals and fruit trees and can transmit plant viruses. Fortunately, many gardeners can keep aphid populations in check not by spraying, but by encouraging the insects and birds that eat them. Lady beetles,…

Aphids are among the most common pests in gardens and farms: tiny, sap-sucking insects that reproduce rapidly, stunt growth, deform new leaves and flowers, and transmit plant viruses. Left unchecked, they can quickly overwhelm ornamentals, vegetables and fruit trees. The instinctive response—reach for a strong insecticide—can be tempting, but many of the broad-spectrum chemicals that…

Every May in Seattle many gardeners notice the same thing: roses and newly leafed fruit trees become smothered in tiny green or black insects almost overnight. That rapid surge in aphid numbers isn’t random — it’s the predictable result of insect biology intersecting with Pacific Northwest spring weather and garden practices. Aphids are uniquely adapted…

Ultraviolet (UV) light traps are a common tool for detecting and managing flying insects indoors. At their simplest they consist of a UV light source and a means of capturing insects that are drawn to that light—either a sticky surface, a removable glueboard, or an electric grid that electrocutes insects. Modern devices use fluorescent tubes…

Pheromone-based pest control exploits the chemical language insects use to find mates, food, or aggregation sites. Insects such as moths and many beetles rely on minute quantities of species-specific volatile molecules—pheromones—to coordinate behavior over distance. By identifying and synthesizing these compounds, researchers and pest managers can create baits and dispensers that either attract insects into…

A pest control follow-up inspection is the critical second act after an initial treatment: it confirms whether the measures taken have worked, identifies any lingering or new pest activity, and determines what additional steps are needed to fully protect the structure and its occupants. Far from a quick walk-through, an effective follow-up must be systematic…

In Seattle, pest control is a heavily regulated profession because of the region’s dense urban environment, sensitive waterways and ecosystems, and public-health stakes. Technicians who apply pesticides or perform structural pest management typically complete accredited training programs that align with Washington State’s regulatory framework—most notably the requirements set by the Washington State Department of Agriculture…
