Seattle homes face spider infestations year-round from attics and basements to garages and living spaces. While one or two spiders may not seem like a big deal, a full-house infestation can quickly grow out of control. Professional spider extermination is the only way to remove the source and keep them from coming back.
Where Spiders Hide in Seattle Homes
- Garages – Dark, cluttered spaces with plenty of insects to feed on.
- Basements & Crawlspaces – Damp areas that attract both spiders and their prey.
- Attics – Undisturbed storage zones with easy access through roof gaps and vents.
- Living Areas – Corners, closets, and behind furniture once infestations spread.

- Webs appearing in multiple rooms or levels of the home
- Egg sacs attached to furniture, walls, or boxes
