Snakes in Colorado: what to know
What to note
Where you see snakes, how long it has been going on, and anything you’ve already tried are the most useful details to mention.

Ask about an inspection, what treatment would involve, and whether follow-up visits are included. You don’t need to identify the problem yourself before getting in touch.

25 species; 2 venomous
Native snake species
Western (prairie) rattlesnake and massasauga are the only venomous snakes in Colorado.

Legal protection
Rattlesnakes may be killed when necessary to protect life or property, subject to local ordinances.
Colorado State University ExtensionWhen snakes are busiest in Colorado
Activity increases in fall as snakes seek hibernation sites; snakes avoid temperature extremes.
CPW lists the prairie, western and midget faded rattlesnakes separately; CSU Extension treats them as one species, Crotalus viridis.
