Yellowstone, Grand Teton, Glacier, and the Canadian Rockies are all places where black and grizzly bears roam. If you are planning on doing any hiking in or around these areas, carrying bear spray is strongly recommended.
Bear spray shoots an average of 30 feet for the duration of 5-9 seconds in fog form. The active ingredient, capsaicin, is derived from chili peppers and is designed to temporarily irritate the bears nose, eyes, throat, and skin giving a person the opportunity to escape unharmed. Bear spray can be purchased in sporting good stores, at national parks, and Amazon and ranges in price from $35-$50.

When do you need bear spray?
Bear attacks are extremely rare, but they do happen.
Yellowstone is known for its bears and since it opened in 1872, only 8 people have been killed by bears. The National Park Service does a great job at training the bears to stay away from people, and the people away from the bears (though there will always be those who don’t listen).
Still, anyone planning on hiking in areas where there are bears present should carry a can of bear spray with them.
We encountered three black bears while hiking on popular trails in Glacier National Park this year. They were literally right on the trail. So don’t ever think it couldn’t happen to you.
What exactly is bear spray?
Bear spray comes in an aerosol can with a safety on it to prevent accidental detination. It can include up to 2% capsaicin which is the nasty stuff found in really, really hot chili peppers that is also found in mace and pepper spray. If you’ve ever cut up peppers without gloves, you’ve experienced a tiny version of the irritation that occurs.
Cans of bear spray range in size, from 7.9 oz to 9.2 oz and can spray the distance of 20-50 feet from anywhere from 5 to 9 seconds in fog form. Many cans come with a holster for quick access. It is recommended that you carry it on your hip or chest instead of your backpack because you may not have time to search for it if you surprise a bear.
What does bear spray do?
In short, it deters a bear from attacking you. When used correctly, the fog like spray discharged from the can will irritate the bears eyes, nose, skin, and breathing to the point that it will stop pursuing you and hopefully run the other way.
Where can I buy bear spray?
National parks with free-roaming bears usually have bear spray for sale at the visitor center. Gas stations in or near the park will also carry it.
If you don’t want to worry about it while you are on vacation, you can purchase some from a sporting goods store like Cabela’s or online at Amazon. They typically range in price between $30-$50 per canister.
Be aware that bear spray is not allowed on airplanes; they consider it a weapon.
You can often rent bear spray from businesses near the national parks or from rental counters inside the national parks. But if you’re visiting for multiple days the cost to rent will often equal or exceed the cost to buy it.
If you buy bear spray but don’t use it, you can recycle it at many places in and around the national parks.

What we learned from our bear spray test
- They all felt equally powerful– Even though there are capsaicin ratings, they were not detectable by the human senses. They all burned our eyes, made us cough, and irritated our skin…… and we were only in the area where it had been sprayed.
- Bear spray is powerful– we were shocked the effect it had on us, even hours after we had tested it. My nose felt like it was on fire until the next morning and my skin burned when I took a shower that night. I can’t emphasize enough that we WERE NOT SPRAYED but were simply in the area that it had been.
- Hold your breath and run the other way- if you ever actually have to use bear spray in an emergency, I recommend holding your breath for the entirety of your spray and then getting out of the area as quickly as you can. Not just to get away from the bear, but to avoid the debilitating effects.
- Release systems all the same– yep, there wasn’t one trigger that was easier or harder than another. They were exactly the same so don’t spend alot of time worrying about that.
- Width is a factor– all the cans of bear spray have a distance claim but none of them mention the width of the fog it produces. There was a difference between brands on our field test and we found Counter Assault and Frontiersman to have a wider spray.
- Testing the actual distance is hard– after 15 feet, the fog really starts to dissipate and you can’t see how far it went. However, the smell will linger in an area far wider than advertised.
- Size is deceiving- Although Guard Alaska came in a 9 oz can and Counter Assault came in an 8.2 oz can, Counter Assault had a wider fog and longer duration, plus a longer range.
- Practice– to be honest, it took me a second to figure out how to hold the can of bear spray and how to release the safety. You can actually purchase a trainer that is just like the real thing, minus the pepper.
One last interesting fact, they all had a different color of fog. The Guard Alaska was orange, Counter Assault was yellow, and Frontiersman was white.
The Best Bear Spray
After researching and testing 3 different brand of bear spray, Frontiersman is the winner. On average, it cost $10 less than Counter Assault, sprayed just as far (Counter Assault’s big claim is they are the furthest spraying bear spray) and for a duration of more than one second longer. Plus, when we sprayed them all, the Frontiersman just felt more powerful.
Tips for buying and using Bear Spray
Buy a test can
Most people won’t go through the effort of spending $100 on bear spray, spraying it in a remote place, and testing it out like us crazy people!
However, you can buy a slightly cheaper test can of bear spray on Amazon.
I highly recommend this because we now feel much more prepared to actually pop the safety tab and fire the spray if a bear was bearing down on us.
Don’t put it in your backpack
Carry the bear spray on your chest or on your belt. Make sure the can you buy has a belt holster to allow for easier carrying and access.
We literally rounded a corner and encountered a bear about 20 feet away in Glacier. Multiple times. You must have quick access to the canister!
Don’t accidentally discharge it
We were on a boat ride in Glacier National Park this year when someone accidentally discharged her bear spray. Everyone in the first three rows were coughing and hacking and running for the bow of the boat.
BE CAREFUL not to accidentally discharge your bear spray!
This was the second time we’ve choked on bear spray; the first was in the video above, LOL.
Disposal of Bear Spray
Bear spray expires and only lasts 3-4 years because the can will eventually lose it’s charge. An expiration date is printed on it so you’ll know when it’s time to dispose of it. Keep in mind that bear spray is a hazardous chemical and can’t just be thrown in the garbage. Here are some ideas
- Contact your local waste management company– they have a process to safely dispose of bear spray and other hazardous materials. This is the best option.
- Wrap it in a bunch of newspaper– this was actually on one of the cans of bear spray. I wouldn’t recommend this. While researching this post, I came across a story of a can of bear spray exploding at a landfill and having to be shut down for a day to clear the air.
- Release the contents before throwing away– I don’t recommend this either. Even if you take safety precautions, you will be coughing and your nose and eyes will burn.
- Recycle it– This is another good option but is only available at the national parks to my knowledge. Just ask a ranger where that particular park accepts expired bear spray and you should be good to go.
