The Gray-Banded Kingsnake (Lampropeltis alterna) is a non-venomous colubrid snake native to the southwestern United States and northern Mexico. Known by other names like "Texas Gray-Banded Kingsnake" or "Alterna," this species is celebrated for its striking appearance and relatively calm temperament.
Adult Gray-Banded Kingsnakes typically reach lengths of 24–36 inches, with some exceptional individuals growing up to 48 inches. Females are often slightly larger than males. Their distinct appearance includes bands of gray interspersed with vibrant orange, red, or yellow patterns, making them visually appealing to reptile enthusiasts. Additionally, genetic color morphs such as albino, hypo, and axanthic exist, though these are less common and often bred selectively in captivity.
In the wild, these snakes have an average lifespan of 10–15 years, but in captivity, they can live for over 20 years with proper care. Native to the rocky deserts and scrublands of Texas, New Mexico, and Coahuila, they thrive in dry, rocky environments with sparse vegetation. Their skin-shedding process occurs every 4–6 weeks, more frequently in juveniles. Breeding in captivity is relatively straightforward with appropriate conditions, making them a popular choice for reptile keepers.

Gray-Banded Kingsnake Care Tips and Common Health Problems
Gray-Banded Kingsnakes are hardy reptiles, but they can encounter common health issues such as respiratory infections, parasitic infestations, and mouth rot (stomatitis). Watch for symptoms like wheezing, swelling, or reduced appetite. Newly acquired snakes should be quarantined for at least 30 days to ensure they are disease-free. Regular cleaning of their habitat and proper hygiene during handling can prevent most health concerns.
Routine grooming includes ensuring they have a rough surface to aid in shedding and keeping their skin healthy. Annual veterinary checkups cost around $50–$100, with annual care and feeding costs ranging from $200–$400, depending on their diet and habitat maintenance. Reliable grooming products, such as shedding aids or disinfectants from brands like Zoo Med and Fluker’s, can be purchased online from reputable pet supply websites.
Gray-Banded Kingsnakes rarely bite and are not venomous. They are shy but calm, and usually avoid confrontation. With gentle handling, they become even more relaxed and unlikely to bite.
They eat small rodents like pinkies and fuzzies. In captivity, frozen-thawed mice are a good choice. Some hatchlings may start slow but typically develop regular eating habits.

Gray-Banded Kingsnake Feeding and Diet
Gray-Banded Kingsnakes are carnivorous and primarily consume small rodents in captivity, such as mice. Younger snakes may also accept small lizards or pinky mice. Feed juveniles every 5–7 days and adults every 10–14 days. Feeding should occur in a separate container to prevent the association of feeding with human interaction, reducing the risk of defensive strikes.
Always ensure the prey is appropriately sized—roughly the same width as the snake’s body at its widest point. Quality frozen-thawed prey is preferred to live feeding for safety. Hydration is critical, so provide clean, filtered water in a shallow dish, refreshed daily. While they typically do not need supplements, occasional treats like small quail can add variety to their diet.

Gray-Banded Kingsnake Habitat Setup Guide
A proper habitat setup is vital for a Gray-Banded Kingsnake’s health and happiness. Juveniles require a 10–20-gallon tank, while adults thrive in enclosures of 40 gallons or larger. Use a secure, escape-proof terrarium from brands like Exo Terra or Zilla.
Substrates such as aspen shavings, cypress mulch, or reptile carpet work well. Include hiding spots, such as caves or logs, and climbing structures like branches. Maintain a temperature gradient of 75°F–85°F with a basking spot around 90°F. Use thermostats and heating equipment from brands like Zoo Med to regulate the temperature. Avoid heat rocks, as they can cause burns.
Clean the habitat weekly, removing waste and replacing water. Deep clean monthly with reptile-safe disinfectants. Include enrichment like climbing toys and tunnels to stimulate their natural behavior. While simulating their natural habitat is possible, focus on creating a functional and safe environment over perfect replication.
Yes, they’re a good option for beginners. They are manageable in size and can be handled with care. Though sometimes shy, they adjust well and are easy to care for.
No, they should be housed separately. They are solitary and may see each other as food. Keeping them alone prevents stress and dangerous interactions.
Things to Consider Before Adopting a Gray-Banded Kingsnake
Gray-Banded Kingsnakes are known for their docile nature and are generally easy to handle, making them suitable for intermediate keepers. They are non-venomous and rarely bite, relying on constriction to subdue prey in the wild. However, they may musk or coil defensively if stressed.
These snakes exhibit unique behaviors like crepuscular activity, where they are most active during twilight. While they can tolerate handling, always support their body fully and approach calmly. Avoid free roaming in the house, as they can escape into small spaces. Gray-Banded Kingsnakes are better housed alone, as cohabitation with other species can lead to stress or predation.

Gray-Banded Kingsnake Price and Buying Tips
When adopting a Gray-Banded Kingsnake, look for alert, healthy individuals with clear eyes and smooth, unblemished scales. Avoid snakes showing signs of illness, such as open-mouth breathing or lethargy. Captive-bred specimens are preferable over wild-caught ones, as they are more acclimated to human interaction and have fewer health issues.
In the United States, prices range from $150 to $400, depending on age, morph, and breeder reputation. They are often available through specialized reptile breeders or expos, but availability in pet stores varies. While generally legal to own, always check local laws, as some states may have restrictions. Internationally, prices and availability differ; they are rarer in countries like India and Japan, often priced higher due to their exotic status.
