David from Monticello, Il writes
Flea Stoppers is a granulated product that will settle to the bottom of carpet and it is highly purified. There are many products that contain the active ingredient Boric Acid but the formulations vary greatly. Regular Borax is more of a powdery formulation which could cause risk of inhalation for pets and people when it is disturbed. Also using Borax as a flea control product is considered an off label usage and not permitted by law.
