What a spider visit looks like.
The tech walks the outside first. They knock down webs and egg sacs around eaves and windows. They treat cracks, gaps and hiding spots, not open lawn. Inside, they focus on corners, closets and the garage. Most visits take about an hour.
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.
