Methoprene disrupts the breeding cycle of adult fleas feeding on an animal. These new products are for long-term treatments and are available from veterinarians. Vacuum the house. Before any insecticides are sprayed, vacuum the floors, carpet, furniture and any other areas to which the pet has access. Wash pet bedding.
Light traps can also be use to catch adult fleas and evaluate areas where flea numbers are high.
These traps are available at many discount stores. When vacuuming, use a heavy-duty household or commercial vacuum cleaner. In some situations, you may want to have the carpets professionally cleaned. Vacuuming carpets with a beater-bar brush can remove a quarter of the flea larvae and more than half of the flea eggs. Vacuuming also stimulates the fleas to leave their protective cocoons.
