No matter how prepared you feel to encounter a black bear on the trail, coming face-to-face with one of these wild creatures can be jarring (speaking from experience).

Maybe it’s because of their 4-inch claws. Or, how they have a biting force strong enough to crack a bowling ball. Or maybe, it’s because they look a lot bigger than first imagined when they're standing only a few feet away.

Though black bears are omnivores and non-aggressive by nature, they will act defensively if they feel threatened. Since coming across one is a high probability for avid hikers or any who venture regularly into bear country, it’s best to know what to do when that happens.

In this post, we’re covering all things black bears, sizing up other animals to be aware of, along with sharing tips from experts like the National Park Service (NPS) and the American Hiking Society (AHS) for how to stay safe on the trail.


Are black bears dangerous?

Compared to grizzlies and mountain lions, black bears are the preferable wild animal you’d want to see on a hike. They are surprisingly timid and aren’t aggressive by nature.

It’s predicted there are around 800,000 black bears in North America living from Canada to Mexico, and everywhere in-between. Statistically, hikers have thousands of interactions with bears every year, very few resulting in physical injury or death.

There’s less than 1 black bear attack a year in the United States, and according to the NPS, the chances of being injured by a bear are 1 out of 2.1 million. Since 1900, there have been 67 fatalities in North America linked to black bears.  That's roughly one fatality every other year. We describe the most recent ones down below.

Why might a black bear attack me?

In most situations they try to avoid humans altogether, acting aggressively only if they feel threatened or frightened.

Being an animal that relies heavily on scent, they’re often drawn into camps or residential areas because of curiosity peaked from strong odors put off by food or dumpsters.

Most black bear attacks occur when a person surprises a bear or gets too close, causing the bear to act defensively (especially if mama bear is walking around with her cubs). Rarely, there have been episodes where a black bear has acted predatorily.

Can they really hurt me?

A black bear charging you is no joke. These guys can weight up to 200 lbs if it's a female and 700 lbs if it's a male. When standing up on their feet, they can measure up to 7 feet. When attacking, bears are known to swing their paws and cause severe scratches with their short, curved claws. Their bite isn't nearly as strong as a grizzly's (about half the force), but depending on its location, would also be enough to put someone's health and life at risk.

Black Bear Attacks vs. Other Wild Animals

When benchmarked against other animal attacks, black bears aren’t the animal to be most worried about. Attacks are incredibly rare, especially compared to other animals that hikers are much more likely to encounter.

The below figures are yearly estimates based on available historical data. United States only.

black bear attacks vs other animals

MOSQUITOS: 100s of Deaths Each Year

Yup, you read that right. Mosquitos make the list, and not only that, these virus-carrying insects are some of the deadliest animals on earth. According to the American Mosquito Control Association, mosquito-related diseases like West Nile, Yellow Fever, Malaria, Dengue, and Zika are responsible for hundreds of deaths every year in the U. S and millions worldwide.

The worst part is these suckers are everywhere, except for maybe Antarctica. But there are preventative measures you can take that include covering up, keeping your camp clean, using mosquito repellents, and staying away from stagnant water sources and damp, grassy areas. Additionally, mosquitos like to come out during cooler times like dusk or dawn and they avoid the hottest parts of the day.

BEES, HORNETS AND WASPS: 62 Deaths a Year On Average

There are 20,000 different species of bees in the world. Well-known for their role in the production of honey, and their powerful sting, these little creatures can become life-threatening to people who experience an allergic reaction when stung.

Since 2000 alone, the CDC reports that bee stings have killed over 1,000 people, with an average of around 62 deaths per year.

The best way to avoid getting stung? According to the CDC, they suggest evading bright-colored clothing, colognes, perfumes, or lotions with powerful scents, and being extra aware around flowers. Also, don’t swat at the bee. Bee’s attack when they feel threatened.

TICKS: 40,000 New Reports of Tick-Borne Illnesses Each Year

Ticks are most active in Spring and Summer and are often found in tall grass and brush. They can carry several diseases, and according to the AHS, the most probable threats to hikers are Lyme Disease and Rocky Mountain spotted fever.

The CDC reports over 30,000 cases of Lyme Disease and 4,000-6,000 tick-borne spotted fevers (including RMSF) a year.

If treated in time, tick-borne illnesses rarely turn serious. A few recommendations from the AHS include wearing light-colored clothing (as this deters ticks), wearing long pants and tucking them into your shoes, using EPA-approved bug spray, and performing a “tick check” when exiting a trail—either visually or by showering and washing your clothes shortly after.

SPIDERS: 7 Deaths a Year on Average

The bad boys here are the brown recluse and the black widow whose venom is toxic to humans, leading to an average of 7 deaths a year in the U.S. While brown recluses primarily live in the south and Midwest, black widows are found nationwide.

Both critters like to hide in spots like rock or woodpiles, holes, in trees, or tucked in discarded shoes, clothing, or sleeping bags.

Preventative measures to keep from getting bit include resisting reaching blindly into areas where spiders like to hang out, avoiding resting against rock piles or trees, and always double-checking your sleeping bag, attire, and boots before slipping into them.

To spiders, humans are not a meal. They avoid us when they can help it, but they will fight back if provoked or surprised.

GRIZZLIES: 45 Attacks Per Year

In a study published by Scientific Reports, there were 664 grizzly attacks reported worldwide from 2000 to 2015 with 14% of these attacks being fatal. Many of the victims were lone, adult hikers, and over half of the run-ins involved female grizzlies and their cubs.

VENOMOUS SNAKES: 7,000 to 8,000 Bites a Year

    In the U.S., the CDC reports that around 7,000-8000 people are bitten by venomous snakes a year. Yet surprisingly, only about 5-6 of these bites result in fatalities. Those most at risk are people in remote areas where medical attention and antivenom are not readily available.

    Many snake attacks occur because the reptile feels threatened and is reacting out of self-defense, or because it’s confused, believing the hand or foot of a person is a smaller animal.

    As for how to avoid snakes, most like to chill in cool, shaded, or damp areas. The AHS says the best practices to avoid getting bitten are to stay on trails, always watch where you step, and avoid rock and woodpiles and tall grass.

    Also, no night hiking. This is when snakes are most active. And if you’re in snake territory, wearing boots, pants, and snake gaiters is a good idea.

    ALLIGATORS, CRORODILES AND MOUNTAIN LIONS: Less than 1 death per year 

    As for mountain lions and alligators, the probability of an attack is low. We count less than 25 fatalities caused by mountain lions in the U.S. in the last 100 years and less than 1 death/year in the U.S. caused by crocodiles and alligators (41 fatalities since the early 1700s).

    How to Safely Avoid and Deter Black Bears

    Black bears are wild animals, and though the number of attacks in the past 100+ years shows they are uncommon, bears can still be just as unpredictable as nature’s temperament tends to be.

    Prevention Tips:

    1. Don’t be afraid to make noise when hiking. Whistle, chat with your fellow hikers, or sing if you so feel inclined. Any noise you can make is a way of giving a bear fair warning that you’re passing through.

    2. Pay attention to your surroundings (no earbuds!) and keep an eye out for fresh tracks or droppings.

    3. Stay away from berry patches, streams, and areas with heavy brush—these are black bears' favorite hangouts.

    4. Keep pets on a leash and be sure to check all guidelines for any area you’re hiking into ahead of time. Many areas that venture through bear country don’t allow pets.

    5. When you stop for the night, always keep all food and any scented items in a bear bag at least 15 feet above the ground or a bear canister. Whichever you use, place it at least 100 yards away from your camp.

    6. Try to put distance between where you cook and eat and where you set up your tent. And don’t leave dirty dishes sitting around.

    7. Don’t keep any scented items in your tent! Including wrappers. Bears have a 7X greater sense of smell than a bloodhound, and if they smell something they like, they’ll be coming to explore it.

    8. Keep a clean camp.

    Encounter Tips: (provided by the NPS)

    1. Most importantly, stay calm and do not run. Chances are you’ve just got a curious bear on your hands and he’s not looking for a quarrel either.

    2. Don’t give your food to the bear—this will just keep it coming back for more.

    3. If you’re wearing a backpack, keep it on. In the rare circumstance the bear attacks, it can provide additional protection.

    4. Face the bear head-on and do your best to appear as big as possible. Wave your arms and stand up straight. If you’re wearing a jacket or sweater, spread it out to make you look larger.

    5. Don’t yell, but speak in a low voice, calmly to the bear. Try your best not to sound threatening. Hearing your voice will help the bear recognize that you’re a human.

    6. Slowly back away from the bear in a diagonal direction while keeping your eyes on it. This movement is a non-threatening gesture.

    7. Either head back the way you came or try to find a detour around the bear at a safe distance. Whatever you do, be sure to leave the bear lots of space, and make sure it’s not following you.

    8. There’s a chance the bear might act defensively by swatting its paws or huffing. This is the bear’s way of telling you to back up and back off.

    9. Always keep a can of bear spray with you and in close reach when venturing into bear country. Use it only if the bear broaches you, and when it gets within range (read the bear spray instructions ahead of time.)

    10. If a black bear becomes aggressive, don’t play dead like you would with a grizzly. Instead, fight back with everything you have using any object at your disposal to attack the bear in the face and nose.
