Habitat and range
Garter snakes are found throughout Minnesota. During the winter, to keep from freezing, they hibernate below the frost line. They usually find a rock crevice, an ant mound or a tunnel made by a burrowing animal. These winter dens are used by garter snakes year after year.
Population and management
Garter snakes are important because they eat destructive rodents (mice) and should not be killed. They have no special status in Minnesota.
Although they are not venomous, garter snakes may bite when handled, and they may defecate on the person holding them, releasing a foul smelling odor.
