Rattlesnakes are an important part of Utah’s ecosystem, helping to control rodent populations and provide shelter for other wildlife. There are five rattlesnake species in Utah, with the Great Basin rattlesnake being the most common. Rattlesnakes are most active during late spring and early summer, especially at dawn and dusk, but can be encountered at any time of day. You’re most likely to see them in rocky benches, high-elevation slopes, and dry canyons, though they can also be found at lower elevations and open areas. Their camouflage allows them to blend into their surroundings, so you may pass by one without noticing.

Rattlesnakes are not aggressive and rarely bite unless they feel threatened. They do not chase people and will usually try to escape if given the chance. Snake bites are rare and typically occur when people try to handle, harass, or kill a rattlesnake. Under Utah law, it is illegal to harass or kill a rattlesnake unless you are defending yourself.

If you encounter a rattlesnake while hiking or recreating outdoors, remain calm and stay at least 10 feet away, giving the snake plenty of space to move away. Do not try to kill, catch, or throw anything at the snake, as this increases your risk of being bitten and is illegal. Always watch where you step or place your hands, and check behind rocks and logs before sitting down. Keep children and pets close by and alert others to the snake’s location so they can avoid the area. If you hear a rattle, stop and locate the sound before moving to ensure you don’t accidentally step closer to the snake.

If a rattlesnake is in a public area or becomes a recurring problem in a residential space, contact your nearest Utah Division of Wildlife Resources (DWR) office rather than taking action yourself. For pet owners, keep dogs leashed on trails and consider rattlesnake aversion training to help them learn to avoid snakes. Not all veterinary clinics carry antivenom, so know in advance which emergency clinics are prepared for snake bites.

In the rare event you are bitten, stay calm and seek medical attention immediately. Do not try to suck out the venom, cut the wound, use a tourniquet, or apply ice, as these methods can make things worse. Remove tight items like rings or watches and keep the bite below heart level while waiting for medical help.

Rattlesnakes play a vital role in Utah’s wild places. By giving them space and respecting their habitat, you can help keep both people and snakes safe.
