Advantix is a good medicine, you can read more about it here:

You could try diatomaceous earth around your yard – it’s a kind of soil that kills fleas because of tiny, microscopic jagged edges that won’t hurt you:

The safest and cheapest method of getting rid of fleas is to use a mixture of boric acid and salt. The powder should be sprayed on carpets, bedding and areas frequented by pets. More information on getting rid of fleas is available at

Try using the 5 % sevin dust.You can put this on dogs over 12 weeks old and also sprinkle in your yard,repeat it about every three weeks and you will be done with fleas soon.You can also bath your pets in the Dawn dish washing liquid to kill fleas.The sevin dust will also rid you of ticks.

I can help! I have 3 dogs and had this problem earlier this year. It was REALLY bad. We tried everything, and I was at my wits end.
Frontline, Advantage and Advantax are all great. BUT, they do not kill the existing fleas in the house or on the animal. What you have to buy is called Capstar (get it from your vet). Give it to all of your dogs. Within hours all of the fleas will drop dead off your dogs. Meanwhile, vacuum the whole house, including furniture. If they sleep on your bed, wash all of the beddding (or anything they do come in contact with). Now you’re ready to apply the Frontline or other topical medicine. Wait 72 hours before bathing them, if you want to. Trust me, this is the only thing that worked for us. I just don’t know why my vet didn’t let me know about Capstar in the first place. We have not had one flea since.

rinse lather and repeat. thats all you really can do. good luck with that problem.
