These US States Don't Have Rattlesnakes

Rattlesnakes pose a danger to tourists and locals in the US. They are aggressive and will bite if they feel threatened. Here’s a guide to states where you won't encounter them.


Recognizable by their distinctive rattling tail, rattlesnakes have triangle-shaped heads and are known for their warning sound produced by muscle contractions in their bodies.

Identified by upturned scales on its nose, this small, camouflaged species climbs trees and blends into leaf litter. It is primarily found in southeast New Mexico.

Cold temperatures make Alaska inhospitable for reptiles. With no lizards, freshwater turtles, or snakes, it’s safe from venomous reptiles due to its freezing climate.


Extreme cold and past human eradication efforts have kept rattlesnakes out of Maine. These snakes cannot survive in the state’s cool temperatures, hiding underground during heat peaks.
