There are three (3) different kinds of venomous snakes in the state of Ohio: the eastern timber rattlesnake, the northern copperhead and the massasauga rattlesnake. Also, each year people report sightings of venomous snakes, but these are incorrect identifications of non-venomous water snakes.

In Ohio, there are region specific guidelines to distinguish venomous from non-venomous snakes. First, venomous snakes have a triangular head, as opposed to the oval-shaped heads of most non-venomous species. Also, they have heat sensitive pits located between the nostrils and the eyes, and their pupils are oval rather than round. Next, venomous snakes have undivided scales between their rectums and their tails on their underbellies. The scales of non-venomous snakes are divided. Plus, the eastern timber rattlesnake and the massasauga rattlesnake are identified by the rattles they make.

So as a rule, you are too close if you can distinguish between a venomous and non-venomous snake.
