- Of Arkansas’ 39 native snake species, six are venomous
- During summer months, snakes are more active at night
- Avoid snakes and bites by walking carefully, using sticks to move debris, wearing close-toed shoes
LITTLE ROCK — As summer approaches in the Natural State, many Arkansans will take to hiking trails, campgrounds, lakes, rivers and favorite swimming holes to enjoy time outdoors. While doing so, it’s important to be aware of Arkansas’ native snakes – including six venomous species – and how to avoid them.
Arkansas has 39 native snake species. Six of these are venomous: the Eastern Copperhead, Northern Cottonmouth, Western Diamond-backed Rattlesnake, Timber Rattlesnake, Western Pygmy Rattlesnake and Texas Gulf-coast Coral snake. Of these, only the Cottonmouth can be found in wetland habitats such as swamps, streams and drainage ditches. For a guide on identifying these venomous species and more information on native snakes, check out the Cooperative Extension Service’s Snakes of Arkansas web page.
While many people fear snakes, deaths from venomous snakebites are rare. From 1983 to 2018, 68 deaths caused by venomous snakes were reported to Poison Control Centers.
Becky McPeake, extension wildlife specialist for the University of Arkansas System Division of Agriculture, said that while seeing a snake in one’s yard can be frightening at first, non-venomous snakes can be an asset to homeowners. They help control other wildlife on the property, preying on rodents, insects, toads, frogs, crayfish, minnows, and even other snakes.
“If you have a non-venomous snake in your yard, you should probably keep it instead of killing it because it could actually be defending its territory against the snakes you don’t want to be there,” McPeake said. “And it’s not going to harm you. As a matter of fact, it’ll be eating mice and other pests that might get into your home.”
McPeake said it’s important to remember that snakes are “more afraid of us than we are of them” and to treat them with respect. To be “snake aware,” follow these guidelines:
- Walk on paths with clear visibility and little ground cover. If walking at night, be sure to use a light source to brighten the path.
- Never step over logs or other obstacles unless one can see the other side. McPeake suggests carefully stepping on top of a log – after checking that there is not a snake resting atop it – and looking on the other side. “Snakes can hide underneath the log, right alongside where it meets the ground, waiting for prey,” she said.
- “Watch where you put your hands,” McPeake said. “Don’t put fingers under debris you intend to move. Flip with a wooden pole to make sure a snake isn’t hidden underneath.”
- Make noise and be watchful, particularly of where you are about to step.
- Carry a walking stick to clear away leaves, make noise, flip objects and keep balance when peeking over logs or other obstacles before crossing.
- Wear close-toed shoes or boots, as many snakebites result when walking barefoot or wearing sandals around the yard.
- If you encounter a snake, step back and allow it to pass. Snakes usually don’t move fast, and one can retreat from the snake’s path.
Snakes are ectothermic, or “cold-blooded,” which means their body temperature is similar to their surroundings, so they seek particular locations to regulate their temperature. Most snakes prefer to maintain body heat at around 86 degrees Fahrenheit, though they are active in temperatures ranging from 50 to 104 degrees F.
During the hot summer months, snakes are more active at night and seek cooler shelter during the day.
Keep an eye out for snakes while swimming or boating. Cottonmouths are the only venomous snake found in water in Arkansas, and they’re more likely to swim in brackish water such as streams or swamps. McPeake said it’s important to stay alert for snakes in overhanging trees while canoeing or kayaking.
“Look up. If I’m in a canoe, I’m always mentally ready for a snake to drop down, then to pick up the paddle and scoop it out,” she said. “Don’t panic. It seems to me that right when a snake drops, it’s stunned. It will sit there for a second, and that’s your chance to get it out.”
If one does get bit by a venomous snake, McPeake’s advice is simple: go straight to the hospital without delay. For those venturing into more remote wilderness, it’s important to prepare for such an emergency.
“If you’re in a wilderness situation without reasonably close access to a hospital, I would say you need to educate yourself and learn what you need to have in case of a snake bite,” she said.
If you’re sure the bite is from a non-venomous snake, then treat it “just like any other bite or wound,” McPeake said. Clean it, keep it bandaged, and watch it for signs of infection.
McPeake emphasized that though snakes can cause a fright, they will usually avoid a confrontation with people.
“We all may get a shock or surprise when you first see the snake, but you need to realize that the snake is not going to harm you,” she said. “It’s that old saying: it’s as scared as we are. You’re the smarter being. Stay in control, get out of its path, and move on.”
