CB Borid Boric Acid Dust will kill adult fleas but it will not kill their eggs. This particular formulation of boric acid is not labeled to broadcast over your carpet. However, if you have fleas inside your home it is very important to use a product with an IGR in it when treating for fleas. We do have an Indoor Flea Kit which has a dust product labeled for broadcasting over your carpet as well as Alpine Flea Insecticide Aerosol with IGR.
