Many homeowners use boric acid to eliminate or prevent an infestation of pests in the home. Sprinkling boric acid powder behind appliances and furniture in the home can prevent and exterminate infestations of cockroaches, ants and silverfish. It is useful when sprinkled on carpets under furniture to eliminate a flea infestation. Boric acid is also used as a barrier in the home to prevent insects from entering the house.

It has the chemical formula H3BO3 (sometimes written B(OH)3), and exists in the form of colorless crystals or a white powder that dissolves in water. When occurring as a mineral, it is called sassolite.
