Eastern Milk Snake

Lampropeltis triangulum triangulum


Milk Snakes are light brown or gray in color with reddish blotches on their bodies. The blotches are larger on the snakes’ backs and smaller on their sides. Their undersides are white with black patterns.


Milk Snakes measure 24-52 inches in length.



Milk Snakes have a varied diet that consists primarily of rodents, but also includes reptiles, amphibians, birds, invertebrates, and eggs. At Cosley Zoo, the Milk Snake eats mice. The snakes at Cosley Zoo are not fed live prey.


Female Milk Snakes lay about 10 eggs at a time in June or July. The eggs have thick, leathery shells and are buried under dirt or in leaf litter. They hatch in August or September. Newly hatched snakes are extremely bright in color and measure 5-10 inches long. The female leaves the nest shortly after laying the eggs and provides no care for the developing eggs or the young snakes.

Shelter and Space Needs

Milk Snakes can be found in a variety of habitats, including hillsides, fields, and wetlands. They are often found under logs, rocks, or stumps. In the winter, snakes travel to dens where they stay with other snakes for the season. During this time, they go through a process similar to hibernation, in which their body temperatures drop and heart rates and breathing slow down.
