Consult with your veterinarian to get the right flea treatment program for your pet. You will need to bathe your pet in flea shampoo, always starting at the head, and working your way toward the tail. Once your pet dries, you'll need to apply flea medication. Your vet can help you choose the right type for your pet.
Put your pet in a flea-free area of your house, and sprinkle flea powder over all your carpets. This ensures that vacuumed-up fleas will be killed inside your vacuum cleaner.
Vacuum your entire house, including underneath furniture and in crevices. Dispose of the contents of your vacuum cleaner outside.
Use an indoor flea treatment spray that contains chlorpyrifos or methoprene. Your pet must be kept out of the house when this treatment is used.
Vacuum again. Thoroughly vacuum the entire house to remove dead and dying fleas, as well as new ones that have hatched.
Use flea bombs. If the treatment spray didn't cut it, try using a flea bomb or fogger. All people and animals must be out of the house when these products are used. When you get home, vacuum again, and wipe residue off all surfaces.
Use another round of flea bombs three to six weeks after the first. Evacuate all people and animals beforehand, and vacuum the house again when you get home.
Treat your yard with a chlorpyrifos spray made for outdoors. Make sure rain is not in the forecast before you treat the yard.
If these measures do not eliminate the flea problem in your home, contact a professional exterminator. In the case of extreme infestations, an exterminator is almost always going to be necessary.
