Snakes in Wyoming: Identification Guide
Learn to identify Wyoming's native snakes, including venomous Prairie Rattlesnakes and harmless species like Bullsnakes and Garter Snakes.
Quick Answer: Wyoming is home to only one venomous snake: the Prairie Rattlesnake. Non-venomous snakes include the Bullsnake, Plains Garter Snake, and Western Terrestrial Garter Snake. Most snakes are harmless and play a key role in controlling rodents. Always keep your distance if you spot a rattler.
What snakes are found in Wyoming?
Wyoming hosts 13 snake species, only one of which is venomous. The Prairie Rattlesnake (Crotalus viridis) inhabits rocky outcrops and grasslands across the state. Non-venomous species include the Bullsnake (often mistaken for a rattler due to its coloring and defensive hissing), the Plains Garter Snake, the Smooth Green Snake, and the Rubber Boa. A few others like the Western Hognose Snake and the Milk Snake are rare or localized. I remember my first hike near Devil's Tower – a Bullsnake crossed the trail, and its pattern was beautiful.
How can you tell a Prairie Rattlesnake from a Bullsnake?
The easiest way: look at the tail. A rattlesnake has a blunt rattle at the end; a Bullsnake has a tapered tail. Bullsnakes also have a pointed head and round pupils, while rattlers have a triangular head and elliptical pupils. Bullsnakes are constrictors and not venomous. In my field notes from Laramie, I've seen both; the Bullsnake’s hissing can be intimidating but it’s all bluff.
What should you do if you see a snake in Wyoming?
Stay calm and give the snake space. Do not try to handle or provoke it. Most bites happen when people attempt to catch or kill a snake. If you are bitten by a rattlesnake, call 911 immediately, keep the bite below heart level, and remove jewelry near the bite. I carry a first-aid kit with a splint when hiking in the Bighorns.
Where do snakes live in Wyoming?
Snakes in Wyoming prefer warm, sunny areas with cover: rocky hillsides, sagebrush flats, prairie dog towns, and riparian zones. They are most active from April to October. During winter, they brumate in dens, often with other species. I once found a den entrance near a limestone quarry – a real snake city.
