Season and climate affect termite prevention because temperature and moisture directly control termite life cycles, foraging behavior, and the durability and movement of treatment materials: warmer, wetter conditions stimulate swarming and colony growth, elevated humidity and persistent dampness promote wood decay and nesting, and seasonal soil moisture alters how far and how long liquid barriers…

Diatomaceous earth (DE) can kill individual termites by abrading their waxy exoskeleton and causing desiccation after direct, prolonged contact, but it is not a reliable method for eliminating established termite colonies or treating hidden infestations. Its mode of action is physical rather than chemical, so DE must remain dry and be applied where termites actually…

Homes in the Pacific Northwest should be inspected for wood‑destroying insects at least once a year, with properties that have elevated moisture exposure, wooded sites, prior infestations, or recent renovations often requiring more frequent checks (every 3–6 months). This baseline frequency reflects the region’s climate and pest ecology: cool, wet winters and persistent humidity create…

A spider problem should be handled by a professional when infestation levels are large or spreading, when a venomous species is confirmed or suspected, when household members have been bitten, or when repeated attempts at DIY control fail to stop ongoing activity. Professional assessment is warranted not only to identify species and bite risk accurately…

Yes — porch lights do tend to increase the number of spiders around a doorway because they concentrate flying insects that spiders feed on, creating reliable hunting sites that encourage web-building and sheltering nearby. Artificial lighting draws moths, flies, and other nocturnal insects, and many web-building species respond by constructing webs in the eaves, corners,…

Keeping spiders out of a basement starts with removing what attracts them: reduce moisture, eliminate other insects that serve as prey, seal gaps and cracks around foundations, and remove clutter and undisturbed storage where spiders build webs. Effective prevention combines physical barriers (sealed vents, weatherstripping, door sweeps), environmental controls (dehumidifiers, improved drainage, proper grading), and…

The spiders most commonly encountered inside Pacific Northwest homes include the common house spider (Parasteatoda tepidariorum), cellar spiders (family Pholcidae), wolf spiders (family Lycosidae), false widows (Steatoda species), orb weavers that wander indoors (family Araneidae), and a variety of jumping spiders (family Salticidae). These species tolerate or exploit human structures—building corners, basements, attics, crawlspaces, window…

As summer nights cool, spiders commonly move indoors to escape falling temperatures, find more stable microclimates, and take advantage of prey concentrated around human structures. Spiders are ectothermic and sensitive to ambient temperature and humidity; cooler, damper nights make sheltered, dry, and slightly warmer spaces inside houses—attics, basements, wall voids, and window frames—more attractive. At…

More spiders appear indoors in late summer because many common species reach sexual maturity then and disperse in search of mates, food, and sheltered places to overwinter, increasing the likelihood that adults and wandering juveniles will enter buildings. In temperate regions like the Pacific Northwest this seasonal surge is amplified by behaviors such as ballooning…

The most effective tool for removing spider webs around the home is a long-handled duster or broom with a soft microfiber or natural-bristle head, because it lets you reach eaves, corners, and high soffits while capturing and removing silk without shredding the web into airborne debris. A telescoping handle reduces ladder use and keeps you…
