    The Western Rattlesnake

    This is the only deadly poisonous snake in Idaho. They are usually found in rocky areas, but leery around water because they can be found there too! This rattler has a triangle shaped head, the famous rattler on his tail, and a mature rattlesnake is about 3 feet long, although baby rattlers are the most dangerous. They like cool places and are nocturnal, so be particularly careful around nightfall and sunrise.

    North American Racer

    You'll find these snakes primarily in the Boise Foothills. They are a greenish/grey color with a yellow belly as adults and they move very fast in a gliding motion.

    Also known as bullsnakes, these snakes mimic rattlers so, you might  be mistaken, but if you pay close attention you'll realize they don't have a rattle on their tail. Gophersnakes do bite and it's painful, so stay clear.

    Terrestrial Gartner Snake

    This is the most common water snake in Idaho and the one I found in my back yard! Totally creeped me out, but apparently they are harmless. They will bite you if they are provoked but they are not considered aggressive.
