Behaviour

Milksnakes hunt rodents in fields and around buildings, mostly at night. They constrict their prey and vibrate the tail when threatened.

Why they matter

They are rodent predators around farms and are often killed by mistake for copperheads.

Reproduction and lifecycle

Nest — In rotting logs, manure or soil

Living around people

  • It is harmless and eats rodents.

Misconceptions

  • Milk snakes drink milk from cows. Snakes cannot suck milk; they visit barns for the mice.
