Spiders and pets.
Most spiders are no threat to pets. A widow bite can sicken a dog or cat. your vet. Some sprays are risky for cats. Ask the company which products are cat-safe.
What a spider visit looks like.
Most visits take about an hour. 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.
Sticky traps tell you a lot.
They show which spiders you have and where they travel. Set sticky traps along baseboards, behind furniture and in the garage. Check them after a week.
Outdoor lights and spiders.
Motion-sensor lights help too. Porch lights draw insects, and insects draw spiders. Yellow bulbs attract fewer bugs.
Cellar spiders in the basement.
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.
