I was looking and hoping for a product that would have some residual effect on spiders. Unfortunately, Wondercide doesn't do that. I sprayed it around the house, and while I appreciated the scent, it left a waxy film on my floors. This waxy film won't kill the spiders, it just leave me a mess to clean up. I *did* spray it on a spider in the tub, and it killed it on contact. This is what it's designed to do. I don't have time to hunt down ever spider in my house and spray it. Sounds like this is a job for my shoe. Well, I tried. Super bummed it didn't work out.
