Flea infestation can be a vicious cycle that is hard to break.

Frontline,advantix and all flea medication that you put on or give orally to your dog or cat really only kills those fleas on your pet. Even if you get frontline plus that has the ingredient that keeps eggs from hatching it doesn't make it to the carpet. It does nothing for the flea eggs in your carpet and furniture, If you wont to break the flea cycle you need to spray your house with Precor. Sprink Sevan dust on the outside in areas that cats or dogs frequent. You can also sprink Sevan in bedding areas. The Precor keeps the eggs from hatching. I spray with Precor every spring and again during summer. Once a year I add Malithion to my spray mixture. You can buy Precor from an exterminator. Flea powder is nothing but Sevan dust. Sevan dust is a much cheaper alternative that can be sprinkeled in carpet when you have active fleas.
