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