As spring temperatures rise in Tennessee, wildlife officials are warning the public about the emergence of timber rattlesnakes, the largest and most dangerous of the state's four venomous snake species. Experts are advising hikers and dog owners to stay on marked trails, keep pets leashed, and seek immediate medical attention if bitten.

Why it matters

Timber rattlesnakes are found across Tennessee and can pose a serious threat to both humans and pets if encountered. With more people heading outdoors as the weather warms, it's crucial for the public to be aware of the risks and take appropriate safety measures.

The details

State wildlife agencies say timber rattlesnakes can be spotted in heavy forest areas, often coiled near fallen logs or sunning on rocks. If a person or dog is bitten, officials recommend taking a photo of the snake to help medical providers identify the venom and provide proper treatment.

  • As spring temperatures rise in Tennessee, rattlesnakes are emerging from their dens.

What they’re saying

“If they do get bit, making sure you take the picture of the snake, and this goes for humans as well, but take a picture of the snake. If you do have to go to the hospital, doctors can identify that picture by the type of snake and know the venom.”

The takeaway

As Tennesseans head outdoors this spring, it's crucial to be aware of the presence of venomous timber rattlesnakes and take appropriate safety precautions, such as staying on marked trails, keeping pets leashed, and seeking immediate medical attention if bitten.
