In Seattle’s damp, temperate climate, two of the most commonly encountered small ants—odorous house ants and pavement ants—regularly invade homes and yards, and knowing which one you’re dealing with matters for identification and control. At a glance both species are similar in size (small, around 1/8 inch) and dark brown to black in color, so…

Seattle’s famously damp, mild climate creates ideal conditions for moisture-loving pests, and among them carpenter ants are one of the most insidious threats to wooden structures. Unlike drywood pests that need very dry timber, carpenter ants prefer softened, decayed, or water-damaged wood — exactly the sort of material that accumulates around leaky roofs, poorly ventilated…

Rodent infestations are more than a nuisance. Mice and rats in the home carry and spread a wide range of pathogens, parasites and allergens that can make household members seriously ill, contaminate food and surfaces, and even create dangerous airborne hazards. Because rodents are adept at hiding in walls, attics and basements and move freely…

Rats and mice are both common commensal rodents, but they behave in ways that are often quite different — and those differences matter a great deal when you’re trying to prevent or control an infestation. At a glance the distinction may seem trivial: both gnaw, breed quickly and seek shelter and food around human structures….

Hearing scratching or scuttling inside your walls at night is one of those sensations that instantly makes a house feel less like a safe haven and more like a mystery to be solved. Whether it’s a faint, rhythmic scraping or loud thumping that keeps you awake, those sounds can signal anything from harmless nocturnal wildlife…

A garage is one of the most convenient — and most vulnerable — entry points for rodents. Mice, rats, and occasionally squirrels seek the warmth, shelter, and abundant food sources garages often provide, especially as seasons change. An infestation can mean chewed wiring, ruined insulation, contaminated stored goods, and the nuisance of droppings and odors….

Chewed wiring is more than an annoying nuisance — it’s a common, potentially dangerous problem that occurs when the protective insulation around electrical cables is gnawed away by animals, pests or, less commonly, household pets. The insulation is the thin barrier that keeps live conductors from touching each other, metal building components or anyone who…

Seattle’s damp, temperate climate and dense urban neighborhoods make it an inviting place for rats, and older Craftsman homes—beloved for their deep eaves, exposed rafters, broad porches, and complex rooflines—offer plenty of hiding places and access points. Before you can stop an infestation, you need to know where rats are getting in. This introduction explains…

After a downpour in Seattle, it’s not unusual for residents to notice more rats scurrying through alleys, popping up in yards, or even appearing near doorways and storefronts. That surge in sightings isn’t just anecdotal; heavy rainfall repeatedly triggers a cascade of environmental changes that alter rat behavior and force these animals out of their…

Understanding when rats are most active in the Pacific Northwest matters for public health, property protection, and effective pest management. The region’s mild, wet climate and a mix of urban, suburban, agricultural and forested landscapes create conditions that favor several commensal rat species—most notably Norway rats and roof rats—and allow them to behave differently than…
