My 2c:
Advantage has always worked for us, but my cats (for the last five years or so) have always been indoor cats. I understand that Frontline Plus' active ingredient is chemically similar to Advantage, but the product is waterproof.
.
For the house, there is a product called Precor which can be sprayed on furniture, carpet, etc. which interrupts the lifecyle (egss, larva, etc.) of the fleas. Apply it twice, about two and a half weeks apart. I only had to do it once, about three years ago, and have not had a problem since, other than I have a darn near full can of Precor. The only problem with the Precor is that it ain't cheap; it cost around $30 for a sixteen ounce spray can four years ago. But it works; Texas' year-round climate is very much like Florida's, and we haven't had fleas since.
