Telling **venomous vs non-venomous snakes** apart starts with head shape and pupils: venomous snakes usually have a broad, triangular head and vertical pupils, while non-venomous snakes usually have narrower, rounded heads and round pupils. These rules are not foolproof, so if you can’t tell, keep your distance, don’t touch or trap the snake, and call a professional. **TL;DR:** Head shape, pupil shape, and color pattern help separate venomous from non-venomous snakes, but none is a guarantee. The venomous snakes to know in the Southeast are the eastern diamondback rattlesnake, cottonmouth, copperhead, and coral snake, while black racers, corn snakes, and garter snakes are harmless and help control rodents. Snakes come to yards for tall grass, rodents, clutter, and standing water, so mow, clear debris, seal gaps, and control rodents. If you see one, back away, keep kids and pets inside, take a photo from a safe distance, and call a professional if you can’t identify it or it keeps returning. ## **Key Takeaways** - Venomous snakes usually have broad triangular heads and vertical pupils, but these rules aren’t foolproof. - Southeastern venomous snakes are the eastern diamondback, cottonmouth, copperhead, and coral snake. - Coral snakes have red, yellow, and black bands, and harmless mimics such as the scarlet kingsnake follow a different pattern. - Tall grass, rodents, wood piles, clutter, and standing water attract snakes. - Don’t touch, trap, or kill a snake, because many bites happen when people get too close. - Call a professional if you can’t identify the snake, see it repeatedly, or have pets and children outside often.
