How to Identify and Get Rid of Garter Snakes

Garter snakes, often called garden snakes, are widespread throughout North America. The snakes prefer moist environments including damp woodlands, meadows and marshes and therefore aren't common in the Southwestern United States. Garter snakes are generally not a threat to humans. Although not venomous, they can and will bite if cornered or handled. In rare instances, humans develop an allergic reaction to the bite. Garter snakes have different colors and markings depending on the geographical area but are fairly easy to identify.

      Take a picture of the snake using your digital camera. Zoom in to capture as much detail as possible.

      Study the photo and note the body color and pattern, the color of the belly and any facial markings. Common garter snakes have uniformly dark heads that are wider than their necks. Their bodies typically have three light stripes; one stripe runs down the center of the snake's back and the other two run along the sides. They can range in length from 18 to 54 inches.

      Go online and do a search for garter snakes. Match your photo to the photos and descriptions provided on websites. You can also call your local cooperative extension office for assistance.

      Mow your lawn to get rid of tall grass where snakes can hide. The grass also harbors insects and rodents that attract garter snakes. Trim overgrown shrubs and remove any piles of brush or debris.

      Purchase mineral sulfur from your local nursery and sprinkle it along the border of your property. Snakes do not like the taste of sulfur and will be deterred from entering the area. You'll need to reapply the sulfur after it rains. Lawn and garden stores also sell other products specially designed as snake repellents. Unfortunately, the sulfur and the repellents have odors that many humans find repulsive as well.

      Contact animal control officers in your area to see if they will remove snakes. They are more apt to respond if you encounter a nest of garter snakes rather than a single reptile.
