Bear Spray

Though the Interagency Grizzly Bear Committee, created in 1983 to lead the recovery of grizzly bears in the lower 48 states, does not endorse any particular commercial bear spray, it points out in its literature that proper use of bear spray can:

  • reduce the number of grizzly bears killed in self-defense,
  • reduce human injuries caused by bears, and
  • help promote the recovery and survival of the grizzly bear.

In a study in the April 2008 edition of the Journal of Wildlife Management, Tom Smith examines "The Efficacy of Bear Deterrent Spray in Alaska." The study shows that in 72 cases where people used bear spray to defend themselves from brown, black and polar bear, the spray stopped brown bears 92 percent of the time and 98 percent of the people involved were uninjured.

Which bear spray to use

In the rare case of a conflict, bear spray, a high-pressure extract of about 2 percent capsaicin, the chemical that makes peppers hot, and other related capsaicinoids, can get the job done. Recent incidents show bear spray to be more effective than a bullet in diverting or stopping a charging bear, according to the Center For Wildlife Information in Missoula.

One way to begin is to check out the different brands available on the Internet or at your local sporting goods store. Many manufacturers offer helpful product comparisons and detailed user instructions on their Internet web sites. Be especially careful to confirm that you are looking at products registered with the EPA and that are intended specifically for use on bears.

Features to assess when selecting a manufacturer include:

  • the percent of active ingredients: 1.3-2 percent is recommended;
  • spray time: bear experts say 6 to 9 seconds;
  • weight of the canister: at least 7.9 ounces;
  • and spray range: bear experts recommend a range of 25 feet in order to give the bear time to experience the effects of the spray.

Practicing with bear spray

Manufacturers generally recommend practicing the steps necessary to use bear spray including arming the container, spraying, and then restoring the safety clip to disarm the container. First-time users will also want to take a test spray or two. Because the spray is so forceful, it may require some practice to control it, especially if there is any wind. The down side is that every test spray reduces the canister's effective spray time. It is important to track the time remaining on a canister carefully.

Carrying bear spray

  • Each person should carry a can of bear spray when working or recreating in bear habitat.
  • Bear pepper spray should be carried in a quick, accessible fashion, such as in a hip or chest holster.
  • Keep bear spray readily available in your cooking area.
  • Keep bear spray readily available next to your flashlight in your tent.
  • Some experts recommend carrying more than one can of bear spray to ensure you always have the additional spray time you might need if it takes more than one burst to stop a bear, or if you encounter more than one bear.

When to use bear spray

  • Bear pepper spray should be used as a deterrent only in an aggressive or attacking confrontation with a bear.
  • Bear pepper spray is only effective when used as an airborne deterrent sprayed as a cloud at an aggressive animal. It should not be applied to people, tents, packs, other equipment, or surrounding area as a repellent.
  • Do not apply the bear spray to camping gear, tents and backpacks. It does NOT repel bears when sprayed on such items.

Using bear spray

  1. Remove safety clip.
  2. Aim slightly down and toward the approaching bear. If necessary, adjust for cross wind.
  3. Spray a brief shot when the bear is about 25 feet away.
  4. Spray again if the bear continues to approach.
  5. Once the bear has retreated or is busy cleaning itself, leave the area as quickly as possible but don't run. Go to an immediate area of safety, such as a car or building.
  6. Do not chase or pursue the bear.

The most intense effects of bear spray may last 30-45 minutes. It is potent enough to cause extreme discomfort and damage to the eyes if it is accidentally released at close range. Flushing the affected skin with water can help but expect to be uncomfortable for a while.

Bear pepper spray transportation and storage

Do not plan to transport bear spray on commercial airlines, but you can identify suppliers on the Internet in the area where you plan to recreate. Also be aware that extreme heat or cold may affect the performance of the product. Canisters have been known to explode if left in a vehicle in summer. Each canister also has an expiration date.
