I have used Frontline, then Frontline Plus for years and loved it TIL THIS YEAR and I am having the same problem. Fleas are back within 2 weeks. Before it would last at least a month. My brother in Austin, Tx has 3 dogs, 3 cats and they were overrun with fleas. He was putting the Frontline on the dogs, spraying the yard and house and in a week dogs were covered. he would srpay the yard and house again, and give the dogs a flea shampoo batch. Few days, back thick. The Frontline had always worked for him til this year. He finally ended up calling a company his vet suggested and the company came out and sprayed this little worms or bugs called (don't know the spelling but is pronounced ) mnamatodes and that did the trick. They eat fleas.
