This easy-to-use boric acid powder (99% - Orthoboric Acid, 1% - Inert Ingredients) is light blue, odorless, and nonstaining. Kills roaches, water bugs, ants, fleas and silverfish.

Simply apply directly on carpets where pets frequently traffic or sleep at the rate of 1.5 pounds per 150 square feet. Work powder deep into fibers and mat. Any powder visible after application must be brushed into carpet fibers or vacuumed. Allow powder to remain for a period of three weeks to achieve maximum flea control in carpets. Sprinkle around baseboards, under and behind refrigerator, stove, sink, dishwasher, washing machine and dryer. Also, sprinkle into openings around drain pipes and electrical conduits, and in cracks and crevices along baseboards and corners of cabinets, cupboards and closets. Insects walk through the dust, ingest it, and die within hours.
