Bear spray is a powerful deterrent made of capsaicin (the “hot” in hot peppers), which, when used correctly, can deter bear attacks. Bear spray inflames the bear’s eyes and upper respiratory system, causing intense burning and giving you and your loved ones time to escape. Bear spray emerges from the canister at over 70 mph, so it is likely be effective even under windy conditions.
Bear spray is a deterrent, not a repellent; use it only during an encounter with an aggressive bear. Pre-sprayed objects may actually attract bears and other wildlife.
