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…

Pest control is one of those routine home maintenance tasks many homeowners treat as a minor annoyance—until it isn’t. While it’s natural to focus on getting rid of visible invaders such as rodents, ants, cockroaches, termites, bed bugs, and mosquitoes, the act of controlling them can introduce its own set of serious hazards. From acute…

When someone is bitten, the first question is often whether the bite is poisonous — but that term can be misleading. In typical medical usage, “venomous” describes animals that inject toxins through a bite or sting, while “poisonous” refers to animals that are harmful if eaten or touched. For the purposes of assessing risk after…

Most spider bites are minor events: a brief sting, localized redness and swelling, and complete recovery within days. Serious, long-term consequences are uncommon and usually tied to bites from a few medically significant species (for example, Latrodectus — black widows — whose venom is neurotoxic, and Loxosceles — brown recluses — whose venom can be…

Rodent infestations are more than a nuisance or a threat to property — they are a common and underappreciated source of indoor air pollution and a genuine public‑health concern. Mice and rats living inside homes, apartment buildings, schools, and workplaces leave behind droppings, urine, dander, saliva and nesting materials that contaminate dust and surfaces. Those…

Household pests are more than just an irritation or an aesthetic problem: many carry real risks to human health. From microscopic pathogens to painful stings and airborne allergens, the creatures that find their way into our homes can transmit disease, provoke allergic reactions, contaminate food, and even contribute to long-term respiratory problems. Understanding which pests…

When you discover wood that looks “off” in your home—soft, discolored, crumbly, or warped—your first thought may be termite invasion or, alternatively, a leak or long-term moisture problem. Telling the difference matters: termite damage signals an active pest problem that can continue to eat away at structural members, while moisture damage indicates water intrusion that…

The Pacific Northwest presents a particular set of challenges and opportunities for termite management. Its cool, wet climate, abundant forests, and widespread use of wood in homes and landscaping create ideal conditions for dampwood and subterranean termites—most commonly the western dampwood (Zootermopsis spp.) and the western subterranean termite (Reticulitermes hesperus). Unlike hot, dry regions where…

Diatomaceous earth (DE) is often touted as a natural, nonchemical solution for household pests, and many homeowners wonder whether a dusting of DE can control serious wood-destroying insects like termites and carpenter ants. At its core, DE is a fine powder made from fossilized diatoms—microscopic algae with silica-based shells. Its insecticidal action is physical rather…

Few problems pose as stealthy and costly a threat to a home as wood‑destroying insects. Termites, carpenter ants, carpenter bees and wood‑boring beetles can all chew away at structural timbers, trim and siding long before visible signs appear, turning small, fixable repairs into major structural and financial headaches. Routine, professional wood‑destroying insect (WDI) inspections are…
