What a spider visit looks like.
Inside, they focus on corners, closets and the garage. They treat cracks, gaps and hiding spots, not open lawn. They knock down webs and egg sacs around eaves and windows. The tech walks the outside first. Most visits take about an hour.
Sticky traps tell you a lot.
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.
Spiders in the garage.
A door sweep and a sticky trap by the door help. Store things in sealed bins off the floor. Garages collect webs, boxes and insects.
