Vacuum every day and either throw away the bag outside, or empty the canister outside depending on the model that you own. I asked my vet last year what they recommend when our house got fleas from our dog. First we had to switch from Advantage, it didn't work as well. They recommended Knockout spray by Virbac. They use it in office, so I got it on Amazon. It costs about $20 a can, but one can goes a long way, covers about 2000 sq. ft. It worked like a charm and keeps fleas from coming back for7 months. Here is a link to for the spray on Amazon. Good luck.
