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.

Questions people ask
Can I save money by doing part of the work myself?

Is the inspection fee credited toward treatment?
Some companies credit it if you go ahead. Ask before you book. Sometimes.
Why do spiders keep coming back after I clean?
Usually because the insects they eat are still around. Egg sacs and gaps around doors also keep them coming.
