Maxforce Pro Roach Killer Bait Gel is not labeled for spiders. To treat spiders we recommend using a residual spray and making it impossible for the spiders to web.

The spider control kit includes a residual spray, insect glueboards and Web out a spray that makes the surfaces sprayed slick so that spiders cannot web.
