How to Identify Florida's Venomous Snakes
Florida has six native venomous snake species — the eastern diamondback rattlesnake, timber rattlesnake, dusky pygmy rattlesnake, cottonmouth, copperhead, and coral snake — and several of them are frequently misidentified as, or confused with, common harmless species.
The six venomous species
Eastern diamondback rattlesnake and timber rattlesnake (large, heavy-bodied, rattle present), dusky pygmy rattlesnake (small, faint rattle, easy to miss), cottonmouth/water moccasin (found near water, often confused with harmless water snakes), copperhead (rare in Florida, mostly Panhandle). The coral snake (small, banded, red touching yellow).
Don't trust old identification myths
Head shape, swimming ability, and even the classic 'red touch yellow, kill a fellow' rhyme are unreliable on their own. Several harmless species (like non-venomous water snakes and scarlet kingsnakes) closely mimic venomous ones. Positive identification takes training, not folk rules.

What to do if you see a snake and aren't sure
Keep people and pets at a distance, do not attempt to handle or kill it, and send us a photo taken from a safe distance. We identify the species before recommending any removal step. We relocate non-venomous species rather than killing them by default.
