Every Venomous Snake in Your State

Every Venomous Snake in Your State

Snakes remain more common—and more dangerous—than many Americans realize. In fact, except for a handful of states across the country, most are home to at least one of the 20 common species of venomous snakes here in the U.S. According to the CDC, nearly all of them are pit vipers (rattlesnakes, copperheads, cottonmouths), except coral snakes, which belong to a different family.

Despite their fearsome reputation, only one in 500 snakebites in the U.S. are fatal thanks to widespread access to antivenom and medical care. That said, most bites occur between April and October, when snakes are active and people are spending plenty of time outdoors.

To keep you, your family, and your pets safe, it’s important to know which types of snakes might be slithering through your backyard or local park. From the 13 rattlesnake species and Sonoran coral snake in Arizona to the cottonmouths lurking in the Southeast, this state-by-state list of venomous snakes, according to local wildlife and CroFab data, will help you identify any potential threats near you.
