Las Vegas has its share of venomous snakes, including the Mojave Rattlesnake, Desert Sidewinder, and Western Diamondback Rattlesnake. While unlikely to appear near a home, these creatures are spotted in outdoor destinations like Red Rock Canyon and Death Valley.

🐍 About Rattlesnakes

Rattlesnakes are part of the viper family, which accounts for nearly 99% of snake bites in the United States. They’re most active during the spring and early summer when coming out of winter hibernation.

Myth-busting: Rattlesnakes are actually quite timid unless provoked. Their primary defense is to hide, followed by a rattle to fend off potential predators. Biting is a last resort.

⚠️ How to Stay Safe

  • Wear over-the-ankle boots and long pants.
  • Stay vigilant while on hikes.
  • Snake encounters can occur anywhere outdoors, but the chances are higher the further you are from a trail.
  • If you see a snake, alert others in the area.
  • Dogs are curious by nature, so always keep them on a leash.

🏥 Treating a Bite

Rattlesnake bites are extremely painful and potentially deadly if left untreated. If bitten, get away from the snake and seek medical attention as quickly as possible.

Between a bite and receiving medical assistance …

Remain Calm

Anxiety and panic will raise your heart rate, potentially aiding venom spread.

Relax the Affected Area

Remove constrictive clothing (pants, socks, jewelry, etc.) around the bite. Place the affected area in a neutral and comfortable position. Increased movement will help the venom spread faster.

Avoid These Myths

Do not raise the affected area above your heart. The venom will make its way towards your heart faster. Don’t use a tourniquet. Let the wound bleed, then apply a bandage around it without constricting.

If you or someone around you is safely able to, take a picture of the snake. The added information could help speed up medical assistance.
