Winter often brings the mistaken belief that pests are out of the picture — cold weather must keep them away, right? In reality, many common pests see winter as an opportunity. As temperatures fall, rodents, cockroaches, spiders, ants and even some wildlife species move indoors seeking warmth, food and nesting sites. Homes and buildings provide…

Winter is a decisive season for the life cycles and behavior of many pest species. As temperatures drop, day length shortens and food becomes scarce, pests shift from active foraging and reproduction toward strategies that improve survival through cold months. Some species enter diapause or hibernation, dramatically slowing metabolism and halting outward activity; others remain…

Seattle’s coastal, temperate climate — characterized by mild winters, wet autumns and winters, and relatively warm, dry summers — creates an unusually hospitable environment for pests. Unlike regions with long, hard freezes that naturally suppress insect and rodent populations, the Puget Sound region rarely sees sustained subzero temperatures. Combined with high year-round humidity, abundant rainfall,…

Pests aren’t random visitors — their activity often follows the calendar. As temperatures, humidity, and food availability shift through the year, insects and rodents adjust their behavior and life cycles accordingly. Seasonal maintenance anticipates those changes and removes the environmental cues and resources that attract or enable pests, turning reactive pest control into proactive prevention….

As winter sets in, many people notice a paradox: pest activity often seems to intensify around transit corridors — highways, rail lines, subways, ports and the paved strips and edges that connect urban and rural places. Those corridors are more than routes for vehicles and goods; they are linear habitats and conduits that concentrate heat,…

Seattle’s distinctive winter — damp, mild, and shaded by dense stands of evergreens and deciduous maples — creates the perfect backdrop for yard debris to accumulate. Heavy rains and seasonal storms strip branches and leaves onto lawns, gutters and porches, while piles of old mulch, firewood and garden waste build up around foundations. What looks…

When winter tightens its grip, many homeowners expect quiet, empty yards — but for rodents, January can be one of the busiest months of the year. Cold temperatures, reduced outdoor food sources, and human behaviors surrounding the holidays combine to make the start of the year a high-risk time for mice, rats, and other commensal…

Cold weather has a complex, sometimes counterintuitive effect on pest sightings in cities. As temperatures drop, many outdoor insect species enter dormancy or die back, so parks and sidewalks can seem noticeably quieter. At the same time, urban pests that can access warm, sheltered microhabitats—buildings, basements, utility tunnels, sewers, and subway systems—often concentrate, become more…

Seattle restaurants face a particular set of pest pressures when winter arrives. Unlike cities with hard freezes that temporarily suppress activity, Seattle’s relatively mild, wet winters and dense urban environment encourage many pests to move inside rather than die off. Rain forces rodents, raccoons, and other wildlife out of saturated burrows and into sheltered spaces;…

Spring in Seattle brings longer days, warmer temperatures, and — for homeowners — a steady uptick in pest activity. Our maritime climate of wet winters and mild springs creates ideal conditions for insects and rodents to emerge, breed, and seek warm, dry shelter. By the time flowers bloom and lawns green up, ants, wasps, rodents,…
