Right, Capstar is basically just an instant flea kill thing rather than a preventer. I've used it in the situation where I missed a dose of the other flea stuff and had to kill the couple fleas she had while waiting for her regular stuff to kick in. I've heard that groomers will sometimes use it to kill fleas on animals that come in to be groomed.
