Frontline does not get rid of fleas in a house. According to Good Dogma, fleas must be killed on all pets, as well as inside and outside of the home to eliminate them.
Frontline is a chemical flea killer and is designed to eliminate fleas on pets. Frontline can also be used as a preventive measure against future flea infestations. Regular vacuuming, dusting and mopping are all ways to help get rid of and prevent fleas. In severe flea infestations, a flea bombing may be necessary to completely kill all of the fleas. Keeping yards clean and free of trash also helps prevent fleas.
