your vet. Some sprays are risky for cats. Ask the company which products are cat-safe. Most spiders are no threat to pets. A widow bite can sicken a dog or cat.
What a spider visit looks like.
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. The tech walks the outside first.
Sticky traps tell you a lot.
Check them after a week. They show which spiders you have and where they travel. Set sticky traps along baseboards, behind furniture and in the garage.
Outdoor lights and spiders.
Yellow bulbs attract fewer bugs. Motion-sensor lights help too. Porch lights draw insects, and insects draw spiders.
Cellar spiders in the basement.
They're harmless and even eat other spiders. A dehumidifier and a broom keep them in check. Long-legged cellar spiders hang in basement corners.
Spiders in the garage.
Store things in sealed bins off the floor. A door sweep and a sticky trap by the door help. Garages collect webs, boxes and insects.
