Bear Spray:
All You Need To Know
As A Hiker

Bear spray: when to use it, and how to use it, are two things every backpacker in brown (grizzly) bear country needs to know.

I have no photos of brown bears to share with you on this page.

That is a very, very good thing.

It means that I've succeeded in keeping a clean backcountry camp, reducing food and garbage odors by using appropriate bear canisters, and thus I've never had a close call with Ursus horribilus/arctos.

Or I'm very lucky.

Either way, Amen!

However, I have plenty of photos of grizzly habitat, because I spend a lot of time there.

So I've taken it as a solemn duty to learn all that I can about brown bears, and to know how to keep myself as safe as possible on backcountry trips using bear deterrent strategies.

Let me share a few tips on how to do that, including the use of a pepper spray specially formulated to deter brown bears in a bad mood.

When to carry
bear spray

If you know you're in brown bear country, you should be carrying bear spray as a bear deterrent.

Defensive spraying has been shown to be very effective at turning away a charging bear.

How do you know you're in grizzly terrain?

If you're planning to hike and backpack in these areas, you need bear deterrents which are non-toxic and most likely to work.

That's bear spray as personal defense, for most of us.

Each hiker in your group should have her own canister of spray like this, and be knowledgeable about its use.

  • Buy bear spray which contains 1.3-2% capsaicin and related capsaicinoids
  • Watch the expiration date, and switch it out when it passes.

When to use bear spray

Your goal in carrying this little canister of unpleasantness is to never have to use it!

However, carrying bear spray may lead to overconfidence and complacency in the backcountry.

Vigilance is required.

Be very careful not to put yourself into a situation where the bear cannot see or hear you.

Examples of behavior to avoid:

  • Napping under a tree
  • Hiking silently through dense brush or near noisy water features
  • Coming around blind corners on the trail without making noise
  • Hiking in early morning or late evening when the bear is most likely to be going about its business of eating

Watch for bear signs

It's your job to remain "bear aware" at all times.

Keep your eyes peeled for bear scat, which are big lumps of you-know-what filled with berries, grass, hair and other signs that the bear is feeding in your area.

Also watch for bear tracks in the mud around streams and springs.

Long vertical scratches on trees and/or freshly stripped bark with weeping sap mean a large predator with sharp nails or claws is in the area.

More ways to
be bear aware

  • Spot their "beds", areas of flattened vegetation where they rest and sleep.
  • Watch for their food caches, large humps of dirt covered carcasses.
  • Take note of dug up patches of stream banks, ant hills, and other areas where they can find insects, roots and other food.
  • Really big rocks that are flipped over are a good bear sign, and a lesson in the power of a bear's claws.

Why would a human hiker waste time and energy doing that?  Bears do!

And it goes without saying, don't go anywhere without your bear spray.

It won't do you any good if it's buried in your backpack, left in your tent while you take a bath in the river, or forgotten in your jacket while you're napping in the sunshine.

The spray goes wherever you are: into the tent at night, especially.

Tip: Every hiker in a group needs a can of bear spray. Don't depend on someone else being there when you need it.

Don't spray right away

When you spot a grizzly, you should be prepared to use the spray.

It should be on the outside of your backpack, within easy reach, or on your belt.

But don't prepare to use it immediately, unless the bear charges you.

  • This can happen when mama bear realizes you are too close to her cubs.
  • It may also happen when you startle a bear near running water or around a blind curve in the trail.

A bear charge can happen lightning fast, and you might not have time to react with your bear spray.

  • Instead, protect your head and neck with your hands, and roll into a ball to protect your vital organs. Lie motionless.

Body language is your clue
to when or if to spray

Bears use body language just like people do.

If the bear is still sizing you up (take that literally), you might have some leeway to "read" its intent.

  • Bears communicate their intent to threaten and intimidate you by making weird noises with their jaws and throat (like snorting and clacking teeth together).
  • They may growl and slap the ground with their paws.
  • They also may salivate, which will highlight their teeth and accentuate their role as a predator.
  • Along the same lines, they position their bodies side ways to appear as large and threatening as possible.

As they are doing this, get your bear spray out of its holster or chest harness, and have it positioned in your hand so you can deploy it without having to look at it.

  • You should have practiced this maneuver at home several times, to get the feel for it without looking.

Your instinct as a small soft creature is to run, or at least get away from that posturing bear.

But in your own best interest it's important to look big and threatening and definitely not like prey.

Use your own body language to send a message:

  • Sing loudly and off key.
  • Wave your arms.
  • Do. not. run. Bad things happen to humans who run from large mammals (cougars included).

If the bear approaches you once it spots you, it means either curiosity or animosity.

There is a possibility of bluff charging, when the bear runs at you but diverts at the last moment.

You won't know if it's a bluff or for real, so once the bear is within 20 feet (6 m), it's time to introduce it to your friend, Bear Spray.

Spray being the operative word.

Even when your hands are shaking.

How to use bear spray

The first thing to remember is that there's a safety clip or cap on top of the can.

  • That has to be released with a quick flick of your thumb in order for the spray to come out.

Back up even further.

The spray can was sold with a zip tie or some other way to lock the safety clip.

  • Be sure that is long gone before you are in a situation where you need to use the spray.

This probably sounds silly as you're sitting in comfort reading this, but you should practice the sequence described below until you can use it without looking at it.

  • Build a body memory of how your hand feels holding it, and where the release for the safety clip is.
  • You can't even believe how scared you'll be when you see a brown bear coming your way, so train your muscles to react even when your mind is screeching.

Here's how to deploy the spray

The spray is only effective if it contacts the mucous membranes of your ursine friend.

So let's make sure that it does.

  • Use both hands to release a 3 - 6 second burst of spray.
  • Then release another one.
  • Aim a bit low. You want to create a mist that will rise up and get the bear's attention as it comes even closer.
  • It would be great if you were downwind of the noxious spray, but you won't have time to make that particular calculation unless you already did while sizing up the bear's behavior (see tip below).
  • Don't drop the can and run. This will be incredibly hard, but do not run.
  • You are hoping for a total yet temporary loss of the bear's ability to continue its attack.
  • Don't turn your back on the bear, because you need to see how it reacts. It should move away from you, reacting to the painful sensation of pepper spray in its face.
  • As the bear begins to leave the area, walk backwards slowly and monitor its actions. You don't want a repeat attack or counter assault to catch you off guard.

Watch this video for a good demonstration of how to use bear spray.


If you have the presence of mind when you meet a bear on a windy day, you can do a test blast (1 second or less) of your canister just to get a sense of where the spray will be carried.

Report the encounter

It's up to you whether or not to tell the local authorities about your run in with a bear.

Filing a report becomes important when the bear's behavior is aggressive and you want to warn others.

It also helps law enforcement and emergency responders put together a pattern in order to locate a rogue bear.

Side effects
of using bear spray

What's bad for the bear's mucous membranes is also horrible for yours.

If a breeze brings some of the irritating vapors into your face, your eyes and nose will run and sting like crazy.

You might have temporary restriction of breathing, temporary restriction of sight, and you will be a lot of discomfort, some might call it pain.

Your only consolation: if it reached the bear, that's what's happening in Bear-ville, too.

Storing your bear spray

To maximize its effectiveness, there are a few things you should do with the spray canister:

Store it in reasonable temperatures to extend shelf life

  • Don't store the canister near heat sources at home, such as a shelf next to the furnace or a large south facing picture window.

Never bring the spray into the passenger compartment of the car without a heavy storage container.

The expiration date is firm, and generous at around 4 years. Once the date has passed, get a new bear spray.

  • You don't want to rely upon the false hope of bear spray that has lost its effectiveness, do you?

What experts say about
efficacy of bear spray

I'm not a bear expert, so all I can do is rely upon the expertise and wisdom of those who are looking at data or working in bear country for long periods of time.

Like me, you can learn from the results of a study which looked at a sample of bear spray incidents in Alaska over the years 1985 to 2006.

Update: The study's pdf has been removed from the Washington Department of Fish and Wildlife website so I can no longer provide the link to it, but I was lucky enough to read it before it disappeared.

Its conclusion:

  • Bear spray makes sense as a personal bear deterrent, and can be used as an alternative to lethal force (carrying a gun).

Summing it up:
be smart and prepared

Isn't it nice to know that the chances of a bear encounter go way, way down if you know how to handle brown bear territory?

First line of defense against a bear attack:

  • Know if you're in bear territory.

Second line:

  • Remain bear aware.

Third line:

  • Avoid confrontation by understanding bear body language.
  • Read a few books.

Fourth line:

  • Buy bear spray and use it correctly as your final line of bear safety.

To be honest, the thrill of seeing these huge creatures is one that will stay with you for the rest of your life.

  • I had the privilege of seeing one on the shore of the Canning River in the Arctic National Wildlife Refuge.
  • And on a trip down the Alsek River (Yukon to Alaska)

Sounds like a thrill you'd rather skip?

Sometimes you have no choice.

Just handle the encounter in the best way possible, which you now know how to do.
