What a spider visit looks like.

Sticky traps tell you a lot.
Check them after a week. Set sticky traps along baseboards, behind furniture and in the garage. They show which spiders you have and where they travel.
Outdoor lights and spiders.
Yellow bulbs attract fewer bugs. Porch lights draw insects, and insects draw spiders. Motion-sensor lights help too.
Cellar spiders in the basement.
They're harmless and even eat other spiders. Long-legged cellar spiders hang in basement corners. A dehumidifier and a broom keep them in check.
Spiders in the garage.
Store things in sealed bins off the floor. Garages collect webs, boxes and insects. A door sweep and a sticky trap by the door help.
