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.

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.
