Garage Pests — Complete Control Guide

Black widow/brown recluse inspection

Inspect under shelving, in boxes, behind stored items, and in undisturbed corners quarterly. Black widows favor protected dark locations at floor level. Use a flashlight and look for irregular cobwebs with a silky texture.

Door seal

The gap under the garage door is a primary entry for mice, spiders, crickets, and cluster flies. Inspect the rubber bottom seal and replace if worn.

Clutter reduction

Spiders are attracted to clutter — cardboard, wood scraps, old boxes, and stacked materials all provide harborage. Annual garage cleanout dramatically reduces spider populations.

Perimeter treatment

Apply bifenthrin spray along the interior walls and floor perimeter in spring — this is the single most effective spider control treatment for garages.

Lighting

Exterior garage lights attract insects, which attract spiders. Switch to yellow/sodium vapor bulbs or motion-activated lighting to reduce insect pressure.
