Bear spray is available in many outdoor, hunting and sporting goods stores. You can also order it online. Canisters labeled “pepper spray,” may not have the correct concentration of ingredients. Instead, look for canisters marked “Bear Spray” or “Bear Deterrent,” with a minimum of 7.9 ounces (225 gr) of product, an EPA registration, a concentration of 1-2% capsaicin and capsaicinoids, a 25-foot (8 m) or more range, and a spray capacity of at least 6 seconds. Check the expiration date to be sure the ingredients have a reasonable shelf life.
