Garter snakes are among the most common snakes in North America—and for many homeowners, they’re also one of the most frequently spotted in the yard or garden. While they’re generally harmless, their sudden appearance can still cause alarm.
In this post, we’ll cover everything you need to know about garter snakes, from how to identify them to what to do if you find one in your home, and when to contact licensed pest control technicians in Atlanta.
What Is a Garter Snake?
A garter snake is a general term used to describe over 35 species of slender, nonvenomous snakes in the Thamnophis genus. These snakes are found across most of the United States and Canada, often living near water or vegetation. Though sometimes confused with more dangerous species, garter snakes are generally harmless and even beneficial, as they help control pest populations like insects, frogs, and rodents.
What Does a Garter Snake Look Like?
Garter snakes are typically small to medium-sized, ranging from 18 to 51 inches long. Their most distinctive features include:
- Longitudinal stripes running down the length of their bodies
- Slender, non-bulky frame
- Round eyes and keeled (ridged) scales
- Colors varying from olive, green, brown, black, red, blue, or yellow
Depending on your location, their patterns may include spots, checkers, or no distinct markings at all. Their appearance can vary dramatically by region and subspecies.
Are Garter Snakes Dangerous?
No, garter snakes are not considered dangerous to humans. While some species have mild venom to subdue prey, they are not a threat to people or pets. However, it’s important not to confuse them with venomous species like timber rattlesnakes, which share some overlapping habitats in the eastern U.S. If handled or threatened, they may:
- Release a foul-smelling musk
- Attempt to bite (usually only if provoked)
If bitten, you may experience mild irritation, swelling, or redness. Wash the bite with soap and water and apply antibiotic ointment. Seek medical attention only if symptoms worsen or if you haven’t had a tetanus shot in the last 10 years.
How Can You Identify Garter Snakes in Georgia and Florida?
Garter Snakes in Georgia
Georgia is home to two main species:
- Eastern Garter Snake (Thamnophis sirtalis sirtalis): 18–26” long, black or olive with yellow/white stripes, occasionally checkered or reddish.
- Eastern Ribbon Snake (Thamnophis saurita): Thin, wispy appearance, up to 28” long, with three distinct yellow stripes and a very long tail.
These snakes are commonly found in marshes, woodlands, backyards, and near water sources like creeks and ponds.
Garter Snakes in Florida
Florida’s warmer climate supports more variety:
- Blue-striped Garter Snake (T. sirtalis similis): Found along the Gulf Coast, known for bright blue stripes.
- Southern Ribbon Snake (T. saurita sackenii): Slender and brownish, found in the Lower Keys and marshy habitats.
- Blue-striped Ribbon Snake (T. sauritus nitae): Similar to the ribbon snake but with blue striping, often seen in northwest Florida.
All of these species are nonvenomous and live near water, gardens, or suburban green areas.
What Attracts Garter Snakes to Your Yard?
Garter snakes are drawn to environments that provide:
- Food: frogs, toads, earthworms, insects, rodents (and occasionally small snakes like rat snakes)
- Water: ponds, marshes, birdbaths, ditches
- Shelter: tall grass, wood piles, rocks, clutter, shaded areas
They’re not picky—if your property offers cover and a steady food supply, they’re likely to move in.
How Do You Keep Garter Snakes Out of Your Yard?
To prevent garter snakes, focus on eliminating the three things they seek: food, water, and shelter.
Yard Maintenance Tips:
- Trim tall grass and remove yard debris
- Eliminate standing water or excessive moisture
- Remove wood piles, logs, and unused play structures
- Seal gaps in siding, crawl spaces, and foundations
Pest Control Support:
- Enroll in a rodent control plan to reduce snake food sources
- Treat the area for frogs, lizards, and insects if overpopulated
Do Garter Snake Repellents Work?
Some people try snake repellents that contain:
- Naphthalene (mothball ingredient)
- Sulfur, cinnamon, clove oil, or garlic
While these products may reduce snake activity temporarily, they often have strong smells that bother humans too—and garter snakes may return after some time.
Our take? Repellents alone aren’t a long-term solution. Prevention and habitat modification work best.
What Should You Do If You Find a Garter Snake in Your House?
It’s rare, but garter snakes may enter your home through:
- Open doors
- Gaps in basement walls
- Cracks near foundations
If you spot one inside:
- Wear gloves and use a broom or towel to gently coax it into a container
- Cover the container and release the snake outside—far from your home
- Seal entry points to prevent future intrusions
If you’re uncomfortable removing it yourself, call a professional snake removal service.
