Approximately 5.8 billion people live in regions around the world that place them at risk for being bitten by “medically important” snakes — meaning venomous species whose bite can have dangerous and potentially life-threatening consequences. Most rattlesnake venom causes hemotoxity and blood-clotting disorders, which lead to disruption of the integrity of the blood vessels and uncontrolled bleeding. The bite location will swell dramatically, with up to a third of the total blood circulation diffusing into tissues. Tissue death can develop within hours to days, and can be severe, requiring long term wound management. Some species of rattlesnake venom can be worse if it is generally neurotoxic, leading to rapid paralysis of the respiratory muscles and suffocation. The combination of toxicities can lead to rapid and severe blood loss, shock, and potentially death.
It is impossible to know, at the time of a bite, how severe the symptoms will be. In part, the severity is determined by the type of snake, the location of the bite, and how much venom was released. The amount of venom released at the time of the bite can vary widely. A snake that strikes because it perceives a great threat to its life may also deliver more venom into its fangs. According to some studies, snakes that have been “grasped” may release more venom for this reason. Not all bites are created equal. Approximately 20-25% of bites are dry, meaning no venom has been injected (this might happen if the snake had recently eaten). 30% of bites are mild, causing local pain and swelling in the bite area but no systemic symptoms. 40% of bites are severe, requiring intensive intervention and longer hospital stays. Only around 5% of bites are fatal.
If you are bitten by ANY snake, seek immediate medical attention if you do not know for absolute certain if it is venomous or not. Call 911 or get to the nearest hospital. At the hospital, snake bite victims may receive antivenin— a medical biological product consisting of antibodies created from horses that have been immunized to the venom. Antivenin binds and neutralized venom toxins. It is extremely important in the treatment of snake envenomation, but is most effective when given within four hours of the bite. It is very expensive, and several vials may be needed in the course of treatment. There is a small risk of allergic reaction to the antivenin due to the equine origin. However, not all venomous bites require anti-venom treatment. Factors such as patient age, bite location, whether the venom is causing severe bleeding near the bite, or circulation issues will determine if anti-venom is needed. Lab tests and a period of observation in the emergency department are helpful, as the symptoms of a venomous bite may take several hours to develop. Local medical protocol will cater to the specific snakes found in a particular area, so treatment may be different from region to region.
What To Do If Bitten By A Rattlesnake:
- Call 911 or get to a hospital as quickly as possible.
- If you can do so safely, try to determine the color of the snake, any patterns it may have, or how big it is.
- Remove any kind of restrictive jewelry or clothing.
- Keep the bitten area below your head and your heart.
Ways of Prevention:
- Keep all bushes and shrubs in your yard and around your home trimmed and off the ground. This is a perfect hiding place for snakes.
- Minimize the rodent population. Rodents attract snakes.
- Rattlesnakes don't always rattle before they strike, so always be aware of your surroundings because they are very good at blending in.
- Always check shoes and boots that have been left outside before putting them on.
- Avoid hiking in tall grass. Stay on trails.
- Watch where you place your hands or where you sit, especially on rock piles or ledges.
- Wear snake gaiters with sturdy footwear to help protect lower legs.

As most of the USA settles into warmer temperatures this time of year, snakes are slithering out of their dens and becoming increasingly more active. Snake season has begun! But that’s not all… it’s also time for the inevitable emergence of spiders and scorpions, too! Yikes! But that doesn’t mean we should avoid the great outdoors and stay home. It just means to take common sense precautions and be aware of your surroundings.
Rattlesnakes usually avoid humans, but about 8,000 people are bitten by venomous snakes in the United States each year, with 10 to 15 deaths, according to the U.S. Food and Drug Administration. One of the best ways to avoid being bitten by a snake is to think about where you put your hands and feet. Look carefully before moving rocks or any object that may be providing shade for a snake. Use caution when walking through fields with tall grass, or along rivers or creeks. Keep in mind snakes are more active in the cooler hours of the day, which means they are more active at night through early morning, so consider installing outdoor lighting fixtures along porches and sidewalks, and carry a flashlight after dark. If you have a backyard swimming pool with a messy log pile next to it and dog food lying out, then you've created the perfect environment to invite rodents, which invites snakes.
Some regions that received more rain than usual this year during the cooler months means there is now plenty of vegetation to feed the rodents and birds that rattlesnakes love to eat. When the ecosystem flourishes, wildlife flourishes, and a number of those birds and rodents are prey to venomous snakes. But that doesn't mean more rattlesnakes now, experts say. That may happen in a couple years, but not until rattlesnakes get fat and happy from plentiful food and make more baby rattlesnakes. As the weather gets warmer, we see snakes come out to sun themselves and look for food, but that doesn’t necessarily mean there are MORE snakes than previous years, it just means all snakes become more active and are therefore seen more often.
Nearly all rattlesnake bites result from human error, not rattlesnake aggression. All rattlesnakes can be aggressive at certain times, but not all rattlesnakes are aggressive in general. Few sounds will make a person freeze or take flight faster than a “rattle,” but since some snakes don’t make that sound, especially baby rattlesnakes, it’s best to assume all snakes are venomous. Although new species of rattlesnakes continue to be discovered, there are currently about 20 species in the United States. The most commonly encountered is the western diamondback; it accounts for the most bites and deaths. They are not aggressive; they're defensive. If you see any type of rattlesnake, don't make it feel threatened and leave a lot of room between you and the snake.
If you are bitten by a rattlesnake or other venomous snake the Mayo Clinic lists these steps:
- Call 911 or go to the nearest hospital as quickly as possible.
- Remain calm and move beyond the snake's striking distance.
- Remove jewelry and tight clothing before you start to swell.
- Position yourself, if possible, so that the bite is at or below the level of your heart.
- Clean the wound, but don't flush it with water. Cover it with a clean, dry dressing.
Be sure NOT to to do these things:
- Don't use a tourniquet or apply ice.
- Don't cut the wound or attempt to remove the venom.
- Don't drink caffeine or alcohol, which could speed your body's absorption of venom.
- Don't try to capture the snake. Try to remember its color and shape so that you can describe it, which will help in your treatment.
Of course your best defense against venomous snakes is not to take a chance in the first place. Wear snake bite protection such as Razer brand lower leg snake gaiters or full Turtleskin brand snake chaps. It’s uncommon for snakes to be active once temps dip below 55°F, but since temperatures like those are months and months away, be safe until then!

Rattlesnake range is extensive— from southern Canada to central Argentina. The thickest concentration is in the US Southwest and northern Mexico, according to the National Wildlife Federation. The estimated 36 rattlesnake species are adaptable, living in forests, grasslands, swamps and deserts Rattlesnakes are "pit vipers" with heat-detecting pits on their heads. Other US snakes in that family are copperheads and cottonmouths, also called water moccasins. These latter two species are concentrated in the central and eastern United States, whereas multiple species of rattlesnakes range across the United States. Fully grown rattlesnakes are typically between 36 and 46 inches long. Most pit vipers typically deliver a "hemotoxic" venom that attacks the circulation system, destroying blood vessels and causing tissue damage. The only other venomous snakes in the United States are coral snakes. Known for their bright bands of red, yellow and black, they are in a different snake family that's related to cobras. They deliver a neurotoxin that disrupts nerve transmission and can cause respiratory failure and paralysis.
Where do snakes hide?
Rattlesnakes constantly hunt for shelter. They hide under logs and in stump holes. They also like woodpiles, thick brush and spaces under boulders, experts say. Pit vipers some times take up residence where people live and work— especially if hiding spots and their food supply (mostly small rodents and lizards) are plentiful. However, rodents are much more likely to get into your house than snakes. If snakes do get into your house, it's most likely you have a rodent infestation. In this respect, rattlesnakes play a key role in balancing the environment. They're mostly eating mice and rats— they're out there doing free pest control.
Do people die from snake bite?
Deaths in the USA from venomous snakes are rare. The US Centers for Disease Control and Prevention estimates about 7,000 to 8,000 people are bitten by venomous snakes in the United States each year. About five of those people die. While human death from a rattlesnake bite is rare, bites will cause a great deal of pain and almost always require a hospital visit to prevent further complications. "The number of deaths would be much higher if people did not seek medical care," the CDC says. World estimates for death by venomous snakebite are much higher -- 81,000 to 138,000 each year.
Rattlesnakes are also afraid of us
Rattlesnakes' reclusive nature is one reason why there aren't more incidents. The rattlesnake actually views humans as a predator; we're a large animal that could eat him. And they're afraid of us, say experts. Rattlesnakes tend to stay hidden. When we encounter a snake on the move, he's usually looking for food or looking for a mate or looking for shelter. Otherwise, he stays hidden because they're so vulnerable to all sorts of predators. Rattlesnakes are "sit-and-wait predators. Some will sit in one place for over a week waiting on a meal. So when there's an encounter, people have generally encroached on their territory.
What to do if a rattlesnake bites you
If you are bitten, seek medical attention as quickly as possible say the experts. If you can, call 911 to come get you. You'll know if you have a serious bite in just a couple of minutes; you can start to feel tingling in your face. According to the California Poison Control System, other symptoms could include:
- Extreme pain and swelling at the bite
- Lots of bleeding
- Nausea, lightheadedness and drooling
- Swelling in the mouth and throat
But what if you can't make that SOS call?
- Keep your heartbeat as low as possible. It takes a while for the venom to work. Don't run, but get yourself somewhere you can make a phone call immediately. There's nothing to really help you from the venom except the serum.
- Stay as calm as possible and deep breathe. Don’t let yourself fall asleep.
- If possible, use a marker or pen and circle where you were bitten in case of swelling. Medical personnel will need to know the bite point.
- Remove jewelry such as rings and tight clothing before you start to swell.
What NOT to do if a rattlesnake bites you
- The best emergency response to a snakebite is car keys and a cell phone!
- Don't employ the out-of-date advice of cut-and-suck (cutting an X at the bite area and sucking the venom out by mouth or suction cups). It's very ineffective; people are likely to do more damage from the knife cut than from the snake bite.
- Do not elevate the affected area! Keep the bite below the level of the heart.
- Don't try to kill the snake to bring to the hospital, and don't take a picture of it unless you can do so easily. Don't comprise your safety by forcing another interaction with an already defensive rattlesnake. Your response to a bite should be the same no matter which type of pit viper bites you.
- Don't apply ice or cold packs to the bite .
- Don't use Advil, Motrin or other nonsteroidal, anti-inflammatory drugs.
- Don’t apply a tourniquet to a pit viper bite. That venom is concentrated and it works like an acid. It breaks down blood vessels and multiple skin tissues. If you confine that venom in that area, you're apt to lose a limb from that. If you allow it to spread, you're more apt to keep your hand or fingers.
How to avoid a snake bite
Rattlesnakes are most active in spring and fall, but vigilance is important all year. Snakes really can venture out in winter on a sunny day. Always be careful where you put your hands and your feet, especially when working around woodpiles or clearing brush. Wear thick gloves. If you're reaching under your house, shine a light under there first to make sure the coast is clear.
- Wear closed-toe shoes or snake proof boots that fangs cannot penetrate. Snake gaiters help protect your lower legs. Snake chaps offer more coverage than just your lower legs.
- Make plenty of noise and vibration while walking. Stick to well-used trails.
- Go around a rattlesnake on a wilderness trail if you spot one.
- If you find a rattlesnake in your yard, call agencies such as your state's natural resources departments or US Fish & Wildlife or contact a biologist at a local college. Do not try to kill the rattlesnake because that's when most people get bit.
- If you must deal with a rattlesnake on your own, use a long branch or pole to gently nudge the snake toward an escape route if you're at least six feet or more away.
- What do you do if you hear that bone-chilling rattle? Experts say if he's rattling, he's alarmed. If you can tell where the snake is, back away. Don't approach. Rattling does not necessarily occur before every bite.

For the average person, chances of a potentially dangerous snake encounter are small. But those of us who hunt, fish, hike and work in the outdoors, are at greater risk because many of the areas we frequent are prime snake habitat. Serpents are shy by nature and do their best to avoid humans, but an unnerving close call with a snake can happen when you least expect it, no matter how experienced you are in the outdoors or how often you are out there. Whether you’re bow hunting, shed hunting, stalking big game, or turkey hunting in a southern swamp or the Texas brush country, you might stumble across a venomous snake, so be prepared. According to herpetologists, there are four groups of venomous snakes in the United States: rattlesnakes, copperheads, cottonmouths/water moccasins and coral snakes.
About 30 species of rattlesnakes inhabit a variety of environments across the U.S. In the eastern half of the country, the timber rattler thrives on rocky ridges and mountain sides from 1,000 to 3,000 feet in elevation. Further south, the timber snake, along with its close relative the eastern diamondback, are at home in swamps and thick, mixed forests. Five different species of western rattlers live in diverse habitats from sea level to 9,000 feet–from the desert to rocky hillsides and canyons, on grassy coastal plains and in conifer forests.
Copperheads are the most numerous and most frequently encountered venomous snake, and have bitten more people in the United States than any other pit viper. Copperheads range from southern New England, south to the southeastern U.S. and west through the Ozarks and into Texas. Their young are hatched between August and mid-September, which is prime time for humans to trek into their their territory.
Cottonmouths are also pit vipers and range roughly from the Carolinas west to Oklahoma and south to Florida and Texas.
Smallest but deadliest of North America’s venomous snakes are two species of coral snake, which belong to the same family as cobras, sea snakes and mambas. Coral snakes are often confused with non-venomous king snakes due to their similar colored band patterns. You can easily distinguish the two if you remember the phrase: “Red touches yellow, kill a fellow. Red touches black, friend to Jack.” There really is some truth to that rhyme.
KNOW WHERE SNAKES LIVE
Wherever you roam, know where rattlesnakes live and especially remember the word “rocks.” Prominent rocky ridges marked with crevices, ledges, and shady dens are all great hiding spots for snakes. Keep an eye peeled as you traverse rocky habitat. If you’re turkey hunting, always check the ground near your setup tree and inside your ground blind before sitting down to call a gobbler. Check the brush at the base of a tree with a stick. Probe the brush with your pole or shooting stick before reaching too close. Many times hunters don’t follow the beaten path that hikers take. When off-trail, avoid thick brush in the woods where a snake might be hiding. The rattlesnake is an ambush predator that hides and coils beside logs and rocks. When you walk up to a fallen tree or large stone, step up on it rather than over it, as there could be a snake lurking on the other side. After ankles and legs, most snake bites occur on hands and arms, so never put your hands in spots where you can’t see what might be hiding there. If you come upon a steep stretch of trail that requires scrambling up and over rocks, check each ledge or crevice.
If you ever hear a rattle or see a snake, back slowly away with no sudden movements. Hold your trekking pole or stick between you and the snake, if you have one. If it lunges, it will go for the pole rather than you. Keep in mind sometimes they rattle, sometimes not, you never know. Beware of silent slitherers! When you are safely away, calm down, catch your breath, make a big detour around the snake and mosey on to enjoy your hike or hunt.
WHAT TO DO IF BITTEN BY A SNAKE
If you are bitten, the Mayo Clinic advises:
- Call 911 immediately or get yourself to a hospital as quickly as possible.
- While waiting for medical help, stay calm and position the body so that the bite is at or below heart level.
- Remove jewelry or tight clothing before swelling starts.
- DO NOT apply ice or a tourniquet on or near the bite.
- DO NOT cut the wound or attempt to suck out the venom.
- DO NOT drink caffeine or alcohol, which could speed the body's absorption of venom.
PREVENT SNAKE BITE
Just like you learn in the Scouts, preparation and prevention are key. Always wear long pants and snake chaps or snake gaiters with thick footwear that fangs cannot penetrate. Knee-high snake proof boots are a good alternative to wearing gaiters if you prefer. We have all heard the basic hunter safety lessons thousands of times and unfortunately, over time we can become complacent. When this happens, the chances of an accident can drastically increase. Safety should always come first, so take time to review not only firearm safety, but basic first aid and these tips on snake bite prevention as well. And please pass your knowledge down to new hunters.

The odds of the “average” person being bitten by a rattlesnake is low— that is, if you’re an “average” city dweller or someone who doesn’t hike, hunt, or work around timber. But what if you spend a great deal of time outdoors in known snake country either working or playing or both? Then you might want to take the threat of snakebite seriously and protect yourself with rattlesnake gaiters or by wearing snake proof boots. The Centers for Disease Control and Prevention report that 7,000 - 8,000 venomous snakebites occur per year in the United States. If you like statistics, here are a few more:
• 55% of people bitten by snakes are male, ages 17 to 27.
• 28% of snakebite victims were intoxicated.
• 50% of bites occur on the feet and legs; 50% are to the fingers and hands.
• 57% of snakebite victims were handling the snake at the time of the bite.
A triangular shaped head and cat-like eyes are giveaways that a snake is venomous. Non-venomous snakes have round heads and round pupils. Venomous snakes will normally be heavier and fatter, too. The Western Diamondback, also called the Pacific Western Rattlesnake, is one of the most common member of the viper family. A common myth about any species of rattlesnake is that they are vicious and go around looking for someone to bite. The fact is that most actually only strike in self-defense or to obtain food. Self-defense includes when they are startled, and that’s exactly when the “average” person is bitten— when they accidentally step on or near a viper, or are working in tall weeds or around wood piles. When not basking out in the sun, most of a snake’s time is spent hiding under a rock or a bush. If you have ever hiked through the woods, chances are you have passed within a foot or so from a rattler and luckily never knew it.
Make no mistake, a bite from a rattler (or copperhead or water moccasin, etc.) can be very serious business. Their venom breaks down the tissue around the bite. When a rattlesnake bites its prey, this action of breaking down the tissue hastens the digestive process and makes it easier for the snake to swallow its prey. If a human is bitten, there is often a loss of tissue around the bite. The snake’s teeth also transfer bacteria and the venom suppresses the immune system of the victim, making it tougher to fight off infection. While this rarely causes death, it can result in the loss of a limb. And the entire process is extremely painful and can be expensive due to the cost of anti-venom.
So why take a chance? If you spend a good amount of time where snakes live, protect yourself by wearing snake proof gaiters or snake proof boots. Luckily, Razer snake gaiters for women and snake gaiters for men are the same product. Children are bitten more frequently than adults. Most children are bitten because they often go barefoot or actually pick up a rattlesnake out of curiosity. Make sure the kids are wearing snake chaps sized just for them.
And if you are bitten, keep in mind that all that stuff about tourniquets, cutting open bites, or trying to suck out the venom has been disavowed by current medical thinking. Don’t apply ice to the wound either. Instead, the advice is simply to seek medical treatment immediately. If you’re a long way from that, try to keep your heart rate down and the bite location below the level of your heart. Your best snakebite kit is your cellphone or your car keys! And although it might be counter-intuitive, avoid killing snakes since they are valuable to our ecosystem. Plus, in many states, illegally killing a snake is a misdemeanor punishable by a fine and/or jail time.
