Bear Spray

Wood Buffalo National Park

What is bear spray?

It is a deterrent containing capsaicin, a chemical found in chili peppers. It comes in a small, portable spray canister and is intended to repel a bear in the event of a close encounter.

What does it do?

The canister releases a cone-shaped cloud of pepper spray to a distance of approximately 10 m and at a speed of over 100 km/h. When a bear walks into the spray, its eyes and skin will sting and it will have difficulty breathing—symptoms nasty enough to prompt a retreat. The spray is non-lethal: the bear will be uncomfortable, but unharmed.

What should I look for when buying bear spray?

  • Check the expiry date
  • Does it have a safety clip?
  • Does it say bear spray or bear repellent? To be legal in Canada, the label must clearly show that it is intended for use on animals; the package volume cannot exceed 500 ml.
  • Size and strength: a 225 ml can (about 10 seconds worth) with 0.75%-1% capsaicin is recommended.

Before hitting the trail

  • Read the instructions.
  • Carry it in a holster you can easily reach with your dominant hand (if you are right-handed, carry it on the right side of your body). If you are biking, place it in the bike’s water bottle rack. Having it in your pack is a no-no—a surprise bear encounter can happen in seconds, and you want to be ready!
  • Practice—spray a short burst outdoors to make sure the can is working properly and to become familiar with the spray radius and your reaction time. Practice reaching for your spray and undoing the safety clip several times. Stores will sometimes have inert cans you can use to get the hang of it.
  • At least one person in your group should carry it, but it’s best if everyone has their own (you want backup, right?).

Getting there

En route to the trail, carry it with the safety clip on in the trunk of your vehicle or in a sealed container. Avoid temperature extremes and the risk of puncturing. It is not permissible to carry bear spray on a commercial airline, even in your checked baggage.

When should I use it?

Bear spray is your “last-resort” tool: have it ready, but try to calmly and slowly get out of the bear’s way first. If the bear comes towards you, yell “Hey Bear!” The bear has to be in close range (less than a bus length) for your spray to be effective. Use only if the bear acts aggressively.

How do I use it?

Remove the safety clip and aim for the bear’s face (make sure the nozzle is pointing away from you). You want to create a wall of spray between you and the bear. Give quick, one-second bursts until the bear retreats. Leave the area immediately. Wind or rain may reduce the spray’s effectiveness; be careful not to get in the path of the spray.

How NOT to use it

Don’t spray it on yourself, your tent or your gear. Studies have found that the lingering smell actually attracts bears! If it can stop a bear in its tracks, imagine what it would feel like on you. Check the label for health precautions.
