They show which spiders you have and where they travel. Check them after a week. Set sticky traps along baseboards, behind furniture and in the garage.
Outdoor lights and spiders.
Motion-sensor lights help too. Yellow bulbs attract fewer bugs. Porch lights draw insects, and insects draw spiders.
Cellar spiders in the basement.
A dehumidifier and a broom keep them in check. They're harmless and even eat other spiders. Long-legged cellar spiders hang in basement corners.

Questions people ask
How long does spider treatment take to work?
