Snakes in Ohio

Ohio is home to roughly 30+ species of snakes, and only 5 of them are venomous. That means the great majority of snakes you meet here are completely harmless and pose no danger to people or pets. Snakes turn up in suburban gardens, woodlots, farm fields, and along creeks across the state, and most are doing useful work eating rodents, slugs, and insects.

The land itself shapes which snakes live where. Glaciers flattened much of northern and western Ohio, leaving behind lakes, marshes, and wet prairie that suit water-loving species. The unglaciated southeast is hill country, with rocky oak woods, ravines, and river valleys that hold the forest snakes. This split between flat glaciated wetlands in the north and rugged wooded hills in the south explains a lot about where different species concentrate.

Ohio records 3 of the historically recognized venomous kinds. The Eastern Copperhead lives in the rocky, wooded hills of the southern and eastern counties. The Timber Rattlesnake clings to a few remote forested ridges and bluffs and is now rare. The Eastern Massasauga is a small, secretive wetland rattlesnake tied to fens and wet prairie; it has declined sharply and is protected. All three are uncommon, and you can spend years in Ohio woods without seeing one.

Most snakes Ohioans actually encounter are harmless. Garter snakes are everywhere, from yards to wetlands. Black rat snakes climb trees and barns hunting mice, watersnakes patrol ponds and streams and are constantly mistaken for cottonmouths (which do not live in Ohio), and fox snakes in the northwest will vibrate their tails and bluff like a rattlesnake when cornered. Bites are uncommon and rarely fatal thanks to antivenom, and nearly all happen when someone tries to handle or kill a snake. Never assume a wild snake is safe to handle, and if a bite happens, call Poison Control at 1-800-222-1222 or 911.
