Tennessee is home to 32 different species of snakes, so it’s little surprise that a few are venomous. Luckily, wildlife control experts know how to handle them. The following snakes are all members of the pit viper family and have a heat sensor behind each nostril that they use to find their prey. Here’s what you should know so you can call for help if you spot one.

The Most-Known Poisonous Snakes in Tennessee

1. Rattlesnakes

Tennessee contains two types of rattlesnake, both of which have the famous rattle on the end of their tails that warn animals to stay away. The timber rattlesnake can be found in wooded areas and forests where it has access to a lot of rodents. Avoiding human contact whenever possible, these snakes are secretive and quiet—despite their heavy bodies and lengths of 36-60 inches.

Pygmy rattlesnakes tend to stick near the flood plain of the Tennessee River, thriving in swamps and marshes to prey on small amphibians. No longer than 20 inches, this snake is small and has a subtle, buzz-like rattle.

2. Western Cottonmouth

Typically found west of the Tennessee River, the Western Cottonmouth snake measures 30-42 inches in length and preys on fish, frogs, and lizards. Dull in color, they have a subtle appearance and will often display the cottony interior of their mouth when approached as a way of standing their ground.

These venomous snakes can swim both above and under the water, so be sure to stay on land and contact wildlife control if you encounter one in a densely populated swimming location.

3. Copperheads

With two species of copperheads germane to Tennessee, it’s important to note that both the northern and southern types are venomous. Typically reaching between 24-36 inches in length, these tan-colored snakes have heads with a coppery appearance, giving them their recognizable name.

They tend to prey on small mice and can be found in debris piles, wooded slopes, or abandoned spaces. They prefer to retreat rather than confront, but you should always keep in mind that they’ll attack if provoked.
