Of the 34 species of snakes that occur in Indiana, only 4 are venomous. Copperheads, cottonmouths, timber rattlesnakes, and massasauga rattlesnakes are the only venomous species found in Indiana, and they are rare and found only in certain parts of the state.
Prevention and Control
Snakes are less likely to frequent an area where they have little cover or food. Control rodent populations around your home, remove piles of junk, rocks, brush and boards, and keep grass mowed.
