Garter snakes, also known as garden or grass snakes, are very common in gardens and residential areas. Garters eat insects, as well as frogs, worms and grubs. They are attracted to warm objects. This gives them the heat they need for digestion and growth.

There are two species of garter snakes in Minnesota. Both have three yellowish, vertical stripes along their body. However, they can be variable in color. Full-grown snakes are usually two to three feet in length.

They sun themselves during the day and hide at night. When approached, garters will try to take cover. If attacked, they will try to defend themselves, but they never offensively attack people or pets.

Control

No chemical poisons or fumigants are registered for snake control. While there are repellents on the market, tests have shown them to be ineffective. To exclude snakes, remove debris, woodpiles and tall grass. Since garter snakes only burrow in loose soil, some hiding places may be eliminated by packing sharp gravel and caulking around stoops and slabs. Remember that garter snakes are harmless to you and your pets and should not be killed.
