Garages are one of the most common places Seattle homeowners discover spider infestations. These spaces are dark, quiet, and often cluttered the perfect environment for spiders to spin webs, hunt insects, and eventually migrate deeper into the home.
Why Spiders Love Garages
- Clutter & Storage – Cardboard boxes, stacked items, and old belongings provide hiding places.
- Moisture – Damp walls, floors, or stored items attract insects and, in turn, spiders.
- Entry Points – Gaps under garage doors, wall vents, or cracks in foundations let spiders move in.

Signs of a Garage Spider Infestation
- Thick webs in corners, rafters, or around stored boxes
- Egg sacs attached to walls or garage items
- Increased sightings of hobo spiders or house spiders in adjoining rooms
