As winter approaches in the Seattle region, homeowners and businesses face the challenge of dealing with various pests seeking shelter from the cold.

Here’s a guide to the common pests you might encounter during the winter months:

Signs of Infestation: Droppings around food packages, in drawers, or cupboards. Gnaw marks on wood, plastic, or wiring. Noises in walls or ceilings, particularly at night.

Prevention Tips: Seal cracks and holes in buildings. Keep food stored in airtight containers. Remove clutter where rodents can hide.

Spiders

Behavior: Many spider species move indoors during winter to seek warmth and prey. They often prefer undisturbed areas like basements, attics, and corners.

Signs of Infestation: Webs in corners or around windows. Sightings of spiders, particularly larger ones, indoors.

Prevention Tips: Seal cracks and gaps around windows and doors. Keep basements and attics clean and clutter-free. Regularly dust and vacuum to remove webs and egg sacs.

Prevention Tips: Keep kitchens and bathrooms clean and dry. Seal cracks and crevices around pipes and baseboards. Store food in airtight containers and clean up spills promptly.
