I had to take Kelly to the vet this AM for a biopsy and while I was waiting for them to take him back I noticed my bouncing baby boy was INFESTED/CRAWLING with fleas. I gave all the Hooligans a Capstar when I got home and will put Frontline on them tomorrow.Originally Posted By: DogrunnerI haven't used program, but I've had good luck with Advantage (not advantix). I give everyone (including the cat) a Capstar 24 hours before I apply it. I'm in Florida with a sandy yard but I only need flea control 2 or 3 months (usually winter, go figure) of the year. It really works.
