Minnesota is home to 17 species of snakes, but none of them are venomous. While this is a good thing for Minnesotans, it is not as exciting for the lovers of dangerous slithering snakes. The only venomous snakes found in the United States are rattlesnakes, cottonmouths (also known as water moccasins), and copperheads. These snakes are found primarily in the southern and western parts of the country, where the climate is warmer.
The Land of 10,000 Lakes has none of those. In Minnesota, the most common snake species are the garter snake, the eastern hognose snake, and the red-bellied snake. These snakes are all harmless to humans and play an important role in the ecosystem by controlling rodent populations and serving as prey for larger animals.
