Killing Native Snakes in TennesseeIt is illegal to kill any species of snakes native to the state of Tennessee, venomous or non-venomous. The only rare exception is made for a homeowner who feels genuinely threatened by a snake. This exception particularly applies to a homeowner who finds a snake inside of their home. It is also legal to defend livestock that are being threatened by a snake. This means that it is always illegal to go out into the wild and kill a snake in its natural Tennessee habitat. Capturing Native Tennessee SnakesIt is also against the law to catch a native Tennessee snake, venomous or non-venomous, and keep it detained as a pet. This includes snakes found in or around your home and snakes taken from the wild. Attempting to keep, harm or kill any native snake is illegal and punishable by fine. If you would like to make one of these native non-venomous snakes a pet, you must purchase it from a licensed breeder.
