The risk of a bear attack while outdoors is incredibly low. However, this doesn’t mean you shouldn’t practice bear safety tactics when in bear country, one of which is carrying bear spray. There are a lot of misconceptions around bear spray though, and also a lot of mistakes which can result in injuries.
After years of camping and hiking in bear country – from Yellowstone to the backcountry of Montana – I’ve learned that having bear spray isn’t enough. You need to understand how to choose it, carry it, and (most importantly) actually use it under pressure. Here’s everything I wish someone had told me before my first grizzly encounter.

What Is Bear Spray?
Bear spray contains a high concentration of capsaicinoids – the compounds that make peppers spicy. When sprayed at a bear, it irritates the animal’s eyes, nose, and respiratory system. The goal is to temporarily incapacitate the bear, giving you critical seconds to leave safely.
Think of it as creating an invisible wall of intense irritation between you and the bear. It doesn’t harm the bear permanently, but it definitely gets their attention and changes their behavior.
Bear Repellent vs. Bear Spray
Even though it’s sometimes called bear repellent, bear spray is not actually a repellent – and this distinction matters.
Bear repellents are preventative measures that help you avoid encounters altogether. Talking, singing, making noise with trekking poles, or using air horns are all repellents because they either keep bears away or scare them off when you spot them at a distance.
Bear spray, by contrast, is a defensive tool. It’s your last line of defense when a bear is displaying aggressive behavior, charging, or attacking. You don’t spray it around your campsite or on your gear to keep bears away – that’s a common and dangerous misconception.

Bear Spray vs. Pepper Spray
Both bear spray and pepper spray contain the same active ingredients, but they’re designed for completely different situations. Here’s what makes them different:
Strength: Bear spray contains 1-2% major capsaicinoids (the maximum allowed by EPA regulations), making it suitable for deterring large mammals. Pepper spray for human defense typically contains a similar concentration but is formulated differently.
Spray Pattern: Bear spray releases a large fog or cloud, making it much easier to hit a charging 400-pound animal that’s moving at 35 mph. You don’t need pinpoint accuracy. Pepper spray releases a stream or smaller fog pattern that requires more precise aim.
Spray Volume: Bear spray releases approximately 1 ounce per second in one continuous stream. Pepper spray releases much less – about 0.1 to 0.2 ounces per second in shorter bursts.
Range: According to EPA regulations, bear spray must reach at least 25 feet. Pepper spray usually maxes out at 6 to 12 feet.
Size: Pepper spray comes in small, keychain-sized canisters. Bear spray requires larger canisters (minimum 7.6 ounces) because you need enough volume to stop a large animal.
I couldn’t find any credible cases where consumer-grade pepper spray successfully stopped a charging bear. Could it work? Maybe. Would it be better than nothing? Absolutely. But if you’re knowingly heading into bear country, don’t rely on pepper spray. Get proper bear spray.

Best Brands of Bear Spray
In the United States, the EPA regulates bear spray. For a product to be legally sold as bear spray, it must meet these specific requirements:
- Contains 1-2% major capsaicinoids
- Minimum content of 7.6 ounces
- Minimum range of 25 feet
- Shotgun cloud spray pattern (also called fog pattern)
- Spray duration of at least 6 seconds
Any EPA-approved bear spray will work effectively. Look for the EPA registration number on the canister to verify it’s legitimate. However, some brands offer features that might better suit your specific needs.
Consider these factors:
Canister Size: Larger canisters spray longer and usually have better range. But they’re also heavier and bulkier – something that matters when you’re backpacking 15 miles. I typically use the standard 7.9-ounce size for day hikes and weekend trips.
Holster Quality: Most bear sprays come with a holster, but not all holsters are created equal. A good holster makes a huge difference in comfort and deployment speed. More on this below.
Strength: The top brands contain 2% active capsaicinoids – the maximum legal limit. There’s no reason to choose anything less potent.
Range: While 25 feet is the minimum, longer range gives you more reaction time. Look for sprays that reach 30+ feet.
EPA-Approved Bear Spray Brands
| Brand | Size | Range | Strength |
|---|---|---|---|
| Sabre Frontiersman | 7.9oz / 9.2oz | 30-35 feet | 2.0% |
| UDAP Pepper Power | 7.9oz | 30 feet | 2.0% |
| UDAP Pepper Power Magnum | 13.4oz | 30 feet | 2.0% |
| UDAP 18HP | 13.4oz | 35 feet | 1.84% |
| Counter Assault | 8.1oz / 10.2oz | 30-40 feet | 2.0% |
My recommendation: I personally use Frontiersman because they offer excellent quick-draw hip belt and chest holster options. The holster quality alone makes it worth the investment.
If you’re thru-hiking in serious grizzly country where retreat isn’t always possible, consider the larger 10.2-ounce Counter Assault (also available at REI) for its impressive 40-foot range, or the UDAP 13.4-ounce canister which can be deployed multiple times before emptying.
Most Effective Way to Carry Bear Spray
Here’s the hard truth: bear spray is completely useless if you can’t access it in 2-3 seconds. Do NOT pack it in your backpack. Do NOT bury it in a side pocket. You MUST have it immediately accessible at all times.
This means wearing the bear spray in a belt or chest holster attached to your body. I prefer chest holsters for hiking because they don’t interfere with my stride or catch on obstacles when I’m scrambling over deadfall. But it’s a personal preference – some people find hip holsters more comfortable.
Do NOT Attach the Holster to Your Backpack
I see this mistake all the time: people clip their bear spray holster to their backpack’s hip belt or shoulder strap. While this keeps the spray accessible while hiking, it creates a dangerous gap in protection.
Think about when you actually take your pack off. Pee breaks. Water breaks. Setting up camp. Filtering water from a stream. Cooking dinner. Taking photos at a scenic overlook. All moments when bears could appear, and your pack – with the bear spray – is sitting on the ground several feet away.
I learned this lesson the hard way when I took my pack off to photograph wildflowers and spotted fresh grizzly scat less than 20 feet away. My bear spray was clipped to my pack, which was leaning against a tree behind me. It was a wake-up call.
For these reasons, a hip belt or chest holster attached to your body is essential. Learn how to make your own DIY bear spray holster if you can’t find one that works for you.
The same principle applies to cyclists and mountain bikers. There are holsters designed for water bottle cages or handlebars, but these only keep spray accessible while you’re riding. Every time you dismount – to push your bike up a steep section, take a break, or fix a mechanical issue – you need to transfer the spray to a body-worn holster.
The bottle holder cage shown above is designed to hold bear spray canisters securely on your bike.
Best Bear Spray Holsters
A quality bear spray holster should meet three critical criteria:
- Hold the canister securely (it shouldn’t fall out when you’re climbing or scrambling)
- Allow for lightning-fast deployment
- Operate silently
Avoid Velcro holsters. This is important. While Velcro does secure the canister, it makes a distinctive ripping sound every time you draw the spray. If a bear hasn’t noticed you yet, that sound can startle it into defensive behavior.
Wildlife biologist Maurice Hornocker described this exact scenario in his book. He encountered a bear and reached for his spray. The Velcro made its characteristic “chrrrrt” sound in the quiet forest, startling the bear. The bear immediately reared up on its hind legs and wheeled toward him – exactly what you don’t want.
Unfortunately, most horizontal-carry holsters (also called cross-draw or trail-runner holsters) use Velcro. Look for holsters with elastic retention straps instead.
The Mystery Ranch holster shown above is my top choice. It’s quick-draw, uses an elastic cord instead of Velcro, and the design keeps the safety clip secure. I particularly appreciate this last feature because I’ve had safety clips fall off while climbing over rocks – not a situation you want to discover when you actually need the spray.
Yes, it’s pricey, but if you spend significant time in bear country, it’s worth the investment.
Does Bear Spray Actually Work?
Bear spray is currently considered the most effective self-defense tool against bears. While nothing is 100% effective, extensive research shows that bear spray stops or prevents aggressive bear behavior in over 90% of encounters.
The statistics are compelling: In close-range encounters with bears, 98% of people carrying bear spray were uninjured. By contrast, people using firearms to defend themselves were injured 50% of the time.
Even when bear spray didn’t completely prevent an attack, it consistently shortened the duration and reduced the severity of injuries. As Chuck Bartlebaugh, director of Be Bear Aware, noted: “I’m not aware of any case, among many I’ve reviewed, of a person dying when deploying bear spray the way it is supposed to be used.”
Does Bear Spray Work on Other Animals?
The Washington Department of Fish and Wildlife states that bear spray will work against almost all wild mammals. While there’s limited formal research on bear spray’s effectiveness against other species, here’s what we know:
Dogs: Pepper spray was originally developed to protect postal workers from aggressive dogs, so yes, bear spray will definitely work on dogs. However, because bear spray is stronger than dog spray, it could severely harm a domestic dog. If you’re not in wilderness areas, use dog spray instead – it contains 1% capsaicinoids (versus up to 2% in bear spray) and shoots in a stream rather than a fog.
Wolves: Wolves have an even keener sense of smell than dogs, making them likely more sensitive to bear spray. Some wolf management specialists recommend carrying it in wolf territory.
Mountain Lions and Bobcats: Zookeepers have successfully used pepper spray on large cats including African lions, tigers, and jaguars. It’s reasonable to assume bear spray would be effective against cougars and bobcats as well.
Moose and Elk: There are documented cases of moose being deterred by bear spray. The Alaska Department of Fish and Game states that as a last resort, pepper spray will often move a moose blocking your path or provide protection if one charges.
Humans: Bear spray will absolutely incapacitate a human – it’s stronger than standard pepper spray. However, because it’s specifically formulated for wildlife defense, using it against a person could open you up to legal liability. Bear spray is for bears, not human attackers.
How to Use Bear Spray
Bear spray is a last resort tool for aggressive bears. Most bear encounters don’t require any spray at all. Simply announcing your presence by talking in a calm, firm voice and slowly waving your arms overhead while backing away is usually enough. Learn more about what to do during a bear encounter.
If the bear shows signs of aggression or begins to charge, here’s exactly what to do.
Important: Remove the Safety Ties BEFORE You Go Out
When you buy bear spray, it comes with plastic zip ties securing the safety clip. You MUST cut and remove these ties before hitting the trail. I’ve met hikers who carried bear spray for an entire week without realizing the safety was still zip-tied. In an actual encounter, they would have been unable to deploy the spray.
Take 30 seconds before your trip to remove those ties. Your future self will thank you.
Step-by-Step Deployment
1. Withdraw the canister and remove the safety clip.
Even if the bear isn’t displaying aggressive behavior yet, remove your bear spray immediately so it’s ready. Bear spray canisters have a safety clip over the trigger. Pull it back with your thumb. Practice this at home so you can do it without looking down.
2. Hold the canister with TWO hands.
You only need one hand to press the trigger, but using two hands prevents common mistakes:
- Spraying hand: Grip the top of the canister. Your index finger goes through the trigger loop, thumb on the trigger.
- Support hand: Hold the bottom of the can with your elbow bent.
This two-handed position prevents you from accidentally spraying the back of your non-spraying hand (which happens more often than you’d think). It also stabilizes the canister and improves your aim when your hands are shaking from adrenaline.
3. Aim downward in front of the bear.
Your instinct will be to aim straight ahead at eye level. Resist this urge. Aiming parallel to your line of sight will send the spray sailing over the bear’s head.
Instead, aim downward toward the ground in front of the charging bear. You want to create a cloud of spray that the bear runs through, not try to hit a moving target.
4. Account for wind.
Ideally, you’re upwind from the bear. If wind is blowing toward you, try to sidestep so it’s not blowing directly into your face. In a crosswind, aim slightly into the wind so the spray drifts into the bear’s path.
This is easier said than done when your heart is pounding, but it’s worth keeping in mind.
5. Spray a warning burst when the bear is 30-60 feet away.
Fire a 1-2 second burst when the bear is still 30-60 feet away. Often, this single burst is enough to deter a bear.
DO NOT WAIT until the bear is close to start spraying. This is critical. Bears can run 35-45 miles per hour. If you wait until the bear is at the 25-foot minimum range, it will cover that distance before the spray takes effect. You’ll end up with an angry, pepper-sprayed bear on top of you.
6. Continue spraying in bursts if the bear keeps coming.
If the bear continues approaching, keep spraying in 1-2 second bursts. Use a side-to-side or zigzag motion to create a large cloud of spray.
Unless the bear is actively charging, resist emptying the entire canister. Save spray for close-range defense if needed.
7. Keep spraying until the bear stops or retreats.
As the bear gets closer, aim directly for its face. Keep deploying spray until the bear stops its aggressive behavior.
8. Leave the area immediately.
Once the bear stops or retreats, back away slowly. Don’t run or make sudden movements. Keep watching the bear to ensure it’s not following.
Leave the area quickly, traveling in a different direction from where the bear went. Report the incident to park rangers or wildlife officials.
If you’re on a multi-day backpacking trip and can’t completely exit the area, hike at least a mile away. Bears sometimes return to the same spot after being sprayed, so don’t set up camp anywhere nearby. Learn more about keeping bears away from your campsite.
9. Clean off bear spray residue.
Here’s the reality: Unless you’re lucky enough to have the wind in your favor, you’re going to get bear spray on yourself. It will get in your eyes, nose, and mouth. Your skin will feel like it’s on fire. It will coat your clothes and gear.
Standard advice for cleaning pepper spray (whole milk on skin, wash with soap, rinse eyes with saline) isn’t feasible in the backcountry. Here’s what actually works:
- Clean your eyes first: Use sterile water without touching your eyes. Wear gloves from your first aid kit, or improvise gloves from plastic bags.
- Strip completely: Get out of all contaminated clothing. Seal it in a plastic bag and don’t touch it again until you can wash it properly.
- Scrub with soap: Bear spray is oil-based, so water alone won’t remove it. Use dish soap if you have it – it’s designed to break down oils.
- Use oil to break down residue: If soap and water aren’t available, use cooking oil, oil-based cream, or petroleum jelly on toilet paper to wipe affected skin. This breaks down the capsaicin oils. Wash with soap afterward if possible.
- Clean gear with alcohol: If you carry alcohol for a camp stove, use it to remove bear spray residue from gear.

Common Bear Spray Mistakes
Not Practicing with the Bear Spray
This is the single biggest mistake people make, and I’m guilty of it myself early in my camping years. Bear encounters happen fast. You need to access and deploy your spray within seconds while adrenaline floods your system. That’s impossible without practice.
If you’ve ever actually deployed bear spray (I used a practice canister), you’ll be surprised by how forceful the recoil is. It can cause you to aim too high, completely missing your target.
Most brands sell inert practice canisters – they’re identical to real bear spray but without the capsaicin. It’s worth every penny.
Practice these skills:
- Drawing the spray from your holster quickly
- Removing the safety in the dark or without looking
- Proper aiming technique
- Firing while keeping your eyes on target
- Adjusting for different wind conditions
Sabre makes an inert practice canister specifically for training.
Test Firing Your Actual Bear Spray
While practicing is essential, never test fire the actual canister you’re taking into bear country.
Most bear spray canisters contain only 7-9 seconds of spray total. The first burst is the most powerful – after that initial spray, the canister loses over half its pressure.
If you’ve test fired your canister, you won’t have enough spray left to effectively repel an attack. The reduced pressure might not propel the spray far enough to reach a charging bear.
Not Having One Canister Per Person
Bear spray costs around $50 per canister, which adds up for a group. But trying to save money by sharing one canister among multiple hikers is dangerous.
First, you’re not together every moment of your trip. I don’t bring company on bathroom breaks, and I often wander away from camp to photograph wildlife or explore.
Second, stopping an aggressive bear sometimes requires more than one canister – especially if the first was deployed too early, aimed incorrectly, or affected by wind. Multiple people with bear spray dramatically increases everyone’s safety.
The more bear spray in your group, the better protected you are.
This set includes two canisters and two holsters.
Using Expired Bear Spray
Bear spray has a shelf life of approximately 4 years. Unlike food expiration dates, this is something you need to take seriously.
The capsaicin remains potent for many years, but the propellant that shoots the spray starts leaking and weakening over time. One study found that bear spray brands lost 0.65 to 1.92 grams of propellant per year.
Expired spray won’t shoot as far or with as much force – potentially leaving you defenseless when you need it most.
What should you do with expired bear spray? Use it as your practice canister.
Keeping Bear Spray in Your Car
Those warnings about bear spray exploding in hot cars? They’re not exaggerating.
There’s the case of a canister that exploded and shredded its holster. Another where the heat turned bear spray into what the owner described as “a spice missile that shattered the windshield and coated the interior in no-no foam.”
Then there’s the nightmare scenario: A canister left in a car after a camping trip ended up wedged under the passenger seat. Months later, the passenger tried to move the seat back while the car was moving and punctured the canister. The driver somehow avoided crashing, but it could have been catastrophic.
The moral? Take those heat warnings seriously. Don’t leave bear spray in hot cars, and put it away in a cool, dry place immediately after your trip.
