Common Winter Pests Our Area


Mice and rats love coming indoors during the winter. This is usually because reliable sources of food have become scarce, and homes tend to have new cracks and crevices in them from building materials contracting with the cold. Seal any gaps where exterior plumbing enters your home, check the weatherstripping on doors and windows, and store food in tightly closed containers to avoid these furry pests.


Cockroaches are incredibly resilient pests, and they haven’t survived our Pacific Northwest winters by luck. Although many roaches either die or go into a state of dormancy when temperatures dip below 50 degrees, German, Oriental, American, and brown-banded cockroaches move indoors to hunker down for the winter. Clean under and around your appliance frequently and keep food particles and moisture at bay to help ward off infestation.


Many homeowners think that spiders die off in the winter, but this is not true. Spiders are considered cold-blooded insects. Many of them enter a slowed, inactive state when temperatures drop and seek shelter outdoors. House spiders and brown recluse spiders, however, can be found in homes during the winter. Sweep any webs away that you find, but take care when killing winter spiders because brown recluses are very dangerous.

Pantry Pests

The holidays are synonymous with freshly baked pies, cookies, and other homemade treats. Indian meal moths, flour beetles, cigarette beetles, and other pantry pests are common in the winter months because people tend to buy and store more flour, spices, and baking products. Be sure to closely inspect all packaged goods that you bring home from the store and call for winter pest control services if you suspect an infestation.


Ants are another resilient pest, and odorous house ants, pavement ants, and carpenter ants remain at large during the winter months. House ants lay eggs well into late fall, and that means they’ll develop into adults during the winter. Pavement ants and carpenter ants may come in during the winter in search of food and water. To avoid infestation, keep a clean home, eliminate water sources, and secure possible entry points.
