OK, this is for the pet parents. We have been fighting an unforgiving group of fleas that keep going after the dog. The sprays, collars, shampoos, & Dawn dish soap (most effective but he can't live with a coating of it on him.) I used the pills & worked but I don't want to spend $40 every six days. The house end of this seems to be OK, the yard needs another spay but the on & off rain gives a small window. I thought the dog was getting under control but today he had almost a dozen when I combed him out as we have been after every trip outside. I'm ready to scorch the grass, rip up the little carpeting we have, & wrap the furniture in plastic. We been good until this year.
