How to Choose the Right Garter Snake: Species, Legality, and Ethical Sourcing
Shopping for a garter snake can be exciting, but the best experience starts with informed choices. Garter snakes belong to the genus Thamnophis, with the common garter snake (Thamnophis sirtalis) being the most widely kept. They’re typically 18–30 inches as adults (some localities get bigger), active during the day, alert, and generally tolerant of careful handling. Because they’re nonvenomous and naturally curious, they’re often recommended for keepers who want a hardy, lively snake that’s smaller than many common boas or pythons.
Before you buy, check local regulations. Some regions protect native populations or restrict possession and collection, and permits can apply by state, province, or municipality. Prioritize captive-bred animals whenever possible: they’re usually healthier, parasite-free, better adjusted to captivity, and less stressful to acclimate and feed. While wild-caught snakes may be inexpensive, they often arrive with mites or internal parasites, and they can be more finicky eaters. Reputable sellers disclose origin (captive-bred vs. field-collected), age, feeding history, and any known health issues.
Red flags when evaluating a garter snake for sale include wheezing, open-mouth breathing, crusty nostrils, bubbles at the mouth, sunken sides, stuck shed, visible mites (tiny black specks that move), and lethargy. A healthy animal is alert, flicks its tongue, has clear eyes between sheds, and holds weight along the spine without a sharp, bony ridge. Ask for a recent feeding video, a clear photo of the snake’s body and head, and an explanation of what the snake is currently eating. Responsible sellers offer a live-arrival or health guarantee, ship overnight in temperature-controlled packaging, and will delay shipping during unsafe weather.
Begin planning quarantine and a dedicated enclosure before the snake arrives. A 30–60 day quarantine away from other reptiles allows time to observe for mites, respiratory signs, or digestive issues. Keep handling light at first, confirm consistent feeding, and maintain a simple enclosure that’s easy to sanitize.

Enclosure Setup and Daily Care: Temperature, Humidity, Diet, and Handling
Good garter snake care starts with a stable, escape-proof enclosure. Adults do well in a footprint similar to a 20-gallon long or larger, with secure top latching. Provide a temperature gradient: a warm side around 80–84°F with a small basking spot at roughly 86–88°F, and a cooler side near 72–75°F. Nighttime drops to room temperature are often fine if your home stays above the mid-to-high 60s. Use a thermostat for any heat source, verify temperatures with a digital probe, and avoid hot rocks. Moderate humidity (about 40–60%) supports healthy sheds, and a roomy water dish lets your snake drink and soak as desired.
Substrates such as aspen shavings, coco husk, cypress mulch, or plain paper towels work well; avoid aromatic woods like cedar or pine. Provide at least two hides (one on each side of the gradient), branches or cork for climbing, and foliage for visual cover. Although UVB isn’t strictly required, low-output UVB (2–5%) and a day/night light cycle can enrich behavior and support overall wellbeing. Replace water frequently, spot-clean waste promptly, and perform a deeper clean every few weeks with reptile-safe disinfectant.
Diet variety is key. In the wild, garter snakes eat amphibians, small fish, earthworms, and more. In captivity, many thrive on a rotation of nightcrawlers (not red wigglers), appropriately sized, unscented pinky mice, and occasional low-thiaminase fish. Avoid goldfish and other high-thiaminase species that can cause vitamin B1 deficiency over time. If offering fish, choose safer options (e.g., tilapia or salmon) and use a reptile-safe thiamine supplement periodically. Juveniles generally eat two to three times per week; most adults do well on weekly feedings. Offer prey that creates a noticeable, but not drastic, bulge and watch for consistent swallowing and normal stools.
Handling should be brief and calm, especially during the first weeks. Support the body with two hands, avoid sudden movements, and never restrain tightly. If your snake musks, don’t worry—this defensive behavior often fades with regular, gentle interaction. During shed cycles, increase humidity slightly or add a moist hide to prevent retained skin. If your snake refuses food, re-check temperatures, try a different prey item, feed in low-traffic hours, and minimize handling for several days. When in doubt, consult a qualified reptile veterinarian for guidance on nutrition and health.
Costs, Breeding Ethics, and Real-World Examples to Inform Better Husbandry
Budget realistically for both the animal and the setup. A typical garter snake might cost $25–$150 depending on locality, pattern, and availability; rare morphs can be higher. Expect to spend roughly $150–$300 on initial equipment: enclosure, thermostat-controlled heat, hides, décor, water bowl, substrate, and optional lighting or UVB. Ongoing costs include electricity, substrate replacement, water conditioner if needed, and food (nightcrawlers and/or feeder rodents). An annual checkup with a reptile-savvy veterinarian provides peace of mind and early detection of issues.
If you’re considering breeding, think beyond the excitement of live-bearing clutches. Many garter species benefit from a seasonal cool-down prior to pairing, and successful breeding can result in sizeable litters. That means more mouths to feed, more enclosures to clean, and the responsibility to place offspring with informed keepers. Ethical breeding practices involve maintaining genetic diversity, documenting lineage, and never releasing surplus animals. Only pair healthy, well-conditioned adults that are feeding consistently and free of parasites.
Real-world examples highlight common pitfalls. One new keeper fed almost exclusively goldfish for months and noticed neurological wobbling and poor appetite—classic signs of thiamine deficiency. After switching to nightcrawlers, pinky mice, and supplementing thiamine, the snake rebounded. Another buyer chose a wild-caught checkered garter because it was inexpensive; within days, mites spread to other reptiles. Strict quarantine and treatment solved it, but the episode underscored the value of captive-bred stock and isolation protocols. A third keeper ran the enclosure too hot and too dry, resulting in stubborn sheds and meal refusals; once the gradient was corrected and a moist hide added, feeding normalized and sheds came off in one piece.
Pay attention to vendor policies. Trustworthy sellers communicate clearly, post recent photos or videos, detail diet and husbandry, and offer a reasonable live-arrival guarantee with weather safeguards. They’ll be transparent about any cosmetic defects, prior treatments, or behavioral quirks. As you gain experience, consider naturalistic or semi-bioactive setups with live plants and leaf litter to encourage exploratory behavior. Provide climbing opportunities, varied textures, and occasional environmental changes to keep a garter snake mentally engaged. With thoughtful planning and a focus on welfare, you can enjoy a hardy, active snake that thrives for years in your care.
