Humans aren’t the only species who like to get outdoors in the summer — it’s also when rattlesnakes are most active. Here are a few tips to keep you and your pets safe when out on the trails.

🐍 All About Rattlesnakes

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

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 well-established trail.
  • If you see a snake, alert other people in the area.
  • Dogs are curious by nature, so always keep them on a leash. You can also enroll your pup in a snake avoidance training program.

🏥 Treating a Bite

Rattlesnake bites can be extremely painful and potentially deadly if left untreated. The two most important steps to take if you’re bitten are to get away from the snake and seek medical attention as quickly as possible. Here’s what to do between the bite and receiving medical assistance:

  • Remain Calm — Anxiety and panic will raise your heart rate, potentially aiding venom spread. If you or someone around you are safely able to, take a picture of the snake. This could help speed up medical assistance.
  • Relax the Affected Area — Remove any constricting items of clothing around the area (pants, socks, jewelry, etc). 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. And don’t use a tourniquet, either. Let the wound bleed, then apply a bandage around it without constricting.

Pennsylvania is home to many snakes, but only some are venomous. Check out this reptile guide for tips on identifying venomous snakes.
