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.
