Outdoor lights and spiders.
Motion-sensor lights help too. Porch lights draw insects, and insects draw spiders. Yellow bulbs attract fewer bugs.

A dehumidifier and a broom keep them in check. Long-legged cellar spiders hang in basement corners. They're harmless and even eat other spiders.
Spiders in the garage.
A door sweep and a sticky trap by the door help. Garages collect webs, boxes and insects. Store things in sealed bins off the floor.
