FIVE FACTS ON GARTER SNAKES

Did you know that garter snakes (Thamnophis sirtalis sirtalis) are among the most common snakes in North America? They are usually 23-30 inches long but have been known to grow up to 53 inches long.

Garter snakes hibernate in the winter, much like a bear.

Unlike most snakes which lay eggs, garter snake babies are born alive. The breeding time is usually
in the late summer when the temperature is conducive. The garter snakes have been known to give birth to around 20 and 40 babies per litter. That’s a lot of snakes.

Garter snakes are harmless, although many people are afraid of them anyway. Their only form of
defense against us is a foul-smelling musky liquid that they release if picked up.

The garter snakes play a vital role in the garden’s ecosystem. When in the garden, the garter snake
usually feeds on  frogs, earthworms and  mice. This helps in the reduction of  crop
damage.
