Brake cleaner kills everything.

We used a powdered product around here when we first moved in. Had a problem similar to yours. Have to ask and get back to this thread.

Found it. Diatect. http://www.diatect.com/kill-spiders-ppc.php

Use it around the house and shop. Should keep the spiders and all other insects away from any area where you frequent. If they cross it......they're dead. Says for indoor use but we used it outside as well and it has worked great.
