I have tried this and a dozen other ''home''flea remedies. All have failed. I have 5 fur babies and they get treated with Advantix and the house gets bombed. I get the Hot Shot bombs at Dollar General -they last longer then Raid bombs. They also get rid of Sand Flea's -Ants -EarWigs and a few other buggy pests. Hot Shot is a water based product, which is a great thing for any one with health issues and they are cheaper. I bombed the middle of May and I'm still bug free and I won't have to do it again til mid August. I put the critters out and I go do my errands.
