Flea pill from the vet given every two weeks until the fleas are gone from your house. If you have carpet, put a flea collar in the dirt collector or bag. The fumes will kill any flea that the vacuum picks up. Also keep your dogs on the heart worm pill with flea control. The medicine causes the fleas to not reproduce so no infestation if she picks up any. The pill we use is Sentinel. It's a once a month pill. We use Revolution once a month for our outside cats and not one has fleas.
