US States That Don't Have Rattlesnakes

Timber Rattlesnake:

Known for being one of the more docile and sluggish rattlesnake species, Timber Rattlesnakes generally don't use their rattle or attack unless disturbed. They inhabit hilly highlands with deciduous forests, meadows, and rocky hillsides.

Western Diamondback Rattlesnake:

This is the largest rattlesnake species, growing up to 8.5 feet long. Known for its distinctive diamond-dorsal pattern and black-and-white bands on its tail, it has bitten more humans in the U.S. than any other rattlesnake species.

Eastern Diamondback Rattlesnake:

The second-longest rattlesnake in America, reaching up to 8 feet, this species has the heaviest body mass. It uses gopher tortoise burrows for hibernation and shelter, and its dark diamond pattern helps it blend into its surroundings.

Pygmy Rattlesnake:

Found in various habitats like pine woods, swamps, and marshes, Pygmy Rattlesnakes are known for their wide range of coloring, from orange-to-red hues to nearly black or patternless varieties.

Ridge-Nosed New-Mexico Rattlesnake:

A threatened species with a small distribution in southeast New Mexico, it is known for the upturned scales along its nose. It can climb trees and plants to better view its prey and often camouflages itself in leaf litter.

Banded Rock Rattlesnake:

One of the smaller species, rarely growing over 2 feet, Banded Rock Rattlesnakes are found at higher altitudes, up to 8000 feet, in mountain ranges. They are exceedingly cryptic due to their color, small size, and speed.

Sidewinder Rattlesnake:

Found in hot, sandy deserts of the American Southwest, Sidewinder Rattlesnakes have distinctive horn-like supraocular scales above their eyes and a spinal ridge. They move sideways to avoid heat absorption from the hot sand.

Mojave Rattlesnake:

Known for having one of the most lethal venoms among North American snakes, Mojave Rattlesnakes inhabit desert regions and are characterized by a dark diamond-shaped pattern on their back and a white band on their tail.

Eastern Massasauga Rattlesnake:

A small, thick-bodied rattlesnake that lives in shallow marshes and is one of only three rattlesnake species in Canada. It is at risk of extinction due to habitat loss and climate change, with gray or reddish-brown coloration and oval-shaped blotches on its back.
