Eliminating fleas from the house and yard is just as important as killing fleas on your pet. Most “house fleas” when they are not on your pet, hide in carpet and moist shaded areas. Insecticides containing IGRs (Insect Growth Regulators) penetrate very deep into the carpet and kills various life stages of the flea for up to 6 months. They generally have a wide safety margin for most mammals. You
still should thoroughly clean and vacuum especially where pets sleep. Sunlight and low humidity also kills fleas. Raking leaves, removing debris, trimming vegetation and spraying permethrin type products in shaded areas of the yard all help in winning the battle against fleas.
