Milk snakes can be found in many parts of the USA. They often approach houses and farms in search of small mammals. Milk snakes are often misidentified as rattlesnakes because of similar structure of the tail and the ability to produce characteristic noise. Milk snakes feature reddish splotches with thin black linings against tan or yellowish background. The belly is usually white. Milk snakes are about 25-30 inches in length.
