Bifen IT is labeled for cracks, crevices and wall voids only when used indoors, meaning that you could not spray it over carpeted areas or on furniture where fleas are most likely to harbor and develop. Ultracide would be a great choice for indoor flea control. Ultracide contains both an insecticide to kill the active biting adult fleas and an IGR to help control developing flea eggs, larva and pupa. For most effective control, vacuum before treating and everyday for the next two weeks, be sure to change the bag or empty the reservoir immediately after vacuuming. A second treatment should be applied after 14 days.
