If you live in a home with hardwood floors, you don't have to worry about fleas hiding out in your carpet fibres. However, this does not mean that there are no fleas to get rid of. Your first course of action when getting rid of fleas should be to treat your animal with a topical or oral flea treatment recommended by your veterinarian. Once your pet is treated, you can begin clearing your home.
Wash and dry all of your pet's bedding. Use hot water. If your pet sleeps in the bed or on any blankets or other washable fabrics, wash those as well.
Vacuum thoroughly every other day for at least one week. Vacuum along the baseboards of the floor and over any cracks, crevices or joints in the floor. Also vacuum any fabric upholstery paying attention to the cracks and crevices there as well and any other places your pet frequents. After you vacuum, remove the vacuum cleaner's bag (or empty the canister) into a plastic bag. Seal the bag tightly and throw it away.
Spray your house with an insect growth regulator (IGR). Spray upholstered furniture, area rugs and mats, the area just inside and outside your home's exit points and any other areas your pet frequents.
Leave the house for three or four hours after you spray IGRs. Leave the windows open and the fan on to help dry the product. Entomologists at the University of Nebraska recommend an IGR that contains methoprene (Precor or Siphotrol) or pyriproxifen (Nylor or Archer). Ohio State University recommends botanicals or IGRs.
