Eastern garter snakes are voracious feeders and will eat anything they can catch and swallow; earthworms, fish, frogs, toads, salamanders, mice, and birds’ eggs are primarily consumed. They will also eat carrion and dead animals of many kinds that are small enough to swallow. They eat their prey without constriction or venom, overpowering their prey with speed and strong jaws.

Hibernation begins in late October. The species uses any place they can get below the frost line. Road embankments, mammal burrows, and and even dug-out basements are common hibernaculums.
