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…

When people talk about pest control credentials they often use the terms “certificate” and “license” interchangeably, but they are not the same. A certificate usually documents completion of a training course or a specific competency—such as safe pesticide application, use of a particular fumigant, or integrated pest management (IPM) techniques—issued by a school, manufacturer, trade…

Pesticides are powerful tools for controlling insects, weeds and other pests, but that power can also pose risks to children, pregnant people, pets and other household members if a product is used incorrectly. The product label is not marketing copy — it is the legal and practical instruction manual for safe use. Learning how to…

Homes with children and pets present a special challenge for pest control. Concern for immediate and long-term health drives many homeowners to seek “safe” or low-toxicity options, but safety alone does not guarantee effectiveness. A practical approach balances minimizing exposure to people and animals with the need to eliminate or control pests reliably. That balance…
