Safety of Using Borax for Fleas

Borax is used in home recipes for flea control when man-made chemicals are to be avoided. While effective for exterminating parasites, its toxicity makes it inappropriate in some applications. Limit its contact with self-grooming pets and small children.

  1. Definition

    • Borax is the generic term for sodium borate or sodium tetraborate. It is harvested through mining. Borax is found naturally in Chile, Tibet, the California desert and in other U.S. states.

    Usage

    • Borax is used in laundry applications and as a component in cosmetics and insulation.

    Method

    • Borax is commercially available in powder form. Sprinkle borax near infested areas and entries. Dust onto upholstery and carpet. Vacuum after ample settling time. Create a sticky compound for larger insects by combining with honey.

    Toxicity

    • While borax is classified as a low-risk pesticide, poisoning can occur through repeated contact. Skin and eye irritation, stunted growth and metabolic issues have been demonstrated in conjunction with boric acid and borax exposure in dogs.

    Precaution

    • Apply borax when the home is unoccupied. Use sparingly near species that self-groom, such as cats and dogs. Licking borax from an irritated paw causes indigestion. Contact a veterinarian or pet poison control line if ingestion is suspected.
