This seems to really work well. I sprayed my front screened in porch and after it dried, I swept all the spider webs away and I haven't seen any new ones to replace them. I waited about a month before posting this review to make sure it was going to work as expected. So far, so good. I really hate spiders, so this is a GREAT product for me!

I didn't read all the fine print and did not realize how small the book was. For the price I should have realized something was off!
