Mexican Black Kingsnakes: Appearance, Origin, and Behavior
The Mexican Black Kingsnake (Lampropeltis getula nigrita) is a striking, non-venomous snake admired for its glossy, solid black scales. It is a subspecies of the common kingsnake, and while it has no other popular aliases, its scientific classification places it within the Colubridae family.
Adult Mexican Black Kingsnakes typically grow between 3 and 5 feet in length, with females often reaching the larger end of the spectrum. Exceptional specimens may grow up to 6 feet. Their smooth, jet-black scales lack any patterns, making them uniquely beautiful. Rare genetic morphs, such as albino or striped variations, are infrequent but can be found among breeders.
In captivity, these snakes can live for 15–20 years with proper care, while in the wild, their lifespan is typically shorter due to predation and environmental factors. Physically, their robust, cylindrical bodies, small, oval-shaped heads, and round pupils are defining traits.
Native to the arid regions of northwestern Mexico and the southwestern United States, Mexican Black Kingsnakes thrive in desert landscapes, scrublands, and areas with sparse vegetation. They are excellent burrowers, often found in loose soil or under rocks. Their shedding process occurs every 4–6 weeks, depending on age and growth. The process begins with dulling of their scales and a cloudy eye appearance. Breeding in captivity is considered straightforward, making them a favorite among hobbyists looking to expand their collection.

Mexican Black Kingsnake Care Tips and Common Health Problems
Like all reptiles, Mexican Black Kingsnakes are susceptible to health issues such as respiratory infections, mouth rot (stomatitis), and skin conditions like retained shed or scale rot. Symptoms include wheezing, discharge from the mouth or nose, swelling, or dull patches on the skin. Quarantining new arrivals for at least 30 days is critical to prevent the spread of illnesses.
Preventive care involves maintaining a clean habitat with optimal humidity and temperature levels. Regularly monitoring your snake’s skin and appetite will help detect issues early. Grooming needs are minimal—routine observation for complete shedding and providing a rough surface for shedding assistance are sufficient.
The cost of caring for a Mexican Black Kingsnake includes an initial setup of $200–$400 for a habitat, substrate, and accessories. Annual expenses, including food and veterinary checkups, range from $100–$300. Reliable products like Zoo Med’s ReptiTherm heat mats and Fluker’s bedding can be purchased online from reputable retailers like Amazon or Chewy.
Mexican Black Kingsnakes can bite if they mistake your hand for food, but they are not venomous. They are usually calm and easy to handle after regular interaction.
Mexican Black Kingsnakes eat mice and small rats. They will eat frozen-thawed rodents easily in captivity. They’re known for strong feeding responses, so use feeding tools when offering food.
Mexican Black Kingsnakes are opportunistic feeders that thrive on a diet of appropriately sized rodents, such as mice and small rats. They are also known to eat birds, eggs, and other reptiles in the wild, though this is unnecessary in captivity. Frozen-thawed rodents are ideal for hygiene and safety.
Young snakes should be fed every 5–7 days, while adults can be fed every 7–10 days. Always use tongs to offer food, ensuring the snake avoids accidentally striking your hand. Feeding them inside their habitat is common, but feeding in a separate enclosure can help prevent substrate ingestion. If they refuse food, check environmental conditions and consider a warm water soak to stimulate appetite. Fresh, dechlorinated water should be available at all times, and occasional vitamin supplements, such as calcium powder, can support health.

Mexican Black Kingsnak Enclosure Setup Guide
For juveniles, a 20-gallon tank suffices, while adults need at least a 40-gallon enclosure. Secure locking lids are essential, as these snakes are skilled escape artists. Suitable substrates include aspen bedding or cypress mulch, which retain humidity and mimic their natural environment.
Hiding spots are crucial for reducing stress—use commercially available hides or natural decor like cork bark. Add climbing branches to encourage activity. Ideal temperatures range from 75–85°F, with a basking spot at 90°F. Maintaining these temperatures requires a combination of heat mats and ceramic heat emitters; products like Zoo Med and Exo Terra thermostats are reliable choices.
A shallow water dish for soaking and drinking is necessary, as is regular cleaning of the enclosure to prevent bacterial growth. Weekly spot cleaning and monthly deep cleans are recommended. Avoid overcrowding or adding unsafe items, such as sharp decor, that could injure the snake. Enrichment items, like climbing perches, can mimic their wild habitat. Housing breeding pairs requires extra care, including separate feeding to prevent aggression.
Yes, they are great for beginners. They are hardy, easy to care for, and can be handled regularly. Their calm nature and bold appearance make them a favorite choice.
Do not keep Mexican Black Kingsnakes together. They are known for eating other snakes, even of the same species. Always give each snake its own enclosure to stay safe.
Things to Consider Before Adopting a Mexican Black Kingsnake
Mexican Black Kingsnakes are calm and easy to handle, making them excellent for beginner and experienced keepers alike. They are non-venomous and generally non-aggressive, although hatchlings may display defensive behavior like musking. With consistent handling, they adapt well to human interaction.
Despite their docile nature, they should not roam freely due to risks like injury or escape. They are solitary creatures and should not be housed with other species. They tolerate children well under supervision, but handling should be limited to avoid stress. Captive-bred specimens are more reliable in behavior compared to wild-caught ones, which may be more prone to stress and disease. Portable habitats can be used for travel, but prolonged outings are not recommended.

Mexican Black Kingsnake Price and Buying Tips
When adopting a Mexican Black Kingsnake, look for a well-fed, active specimen with clear eyes and healthy, smooth scales. Avoid snakes showing signs of lethargy, wheezing, or visible injuries. Captive-bred individuals are preferable for their acclimation to captivity and lower risk of disease.
Paperwork, such as health certifications, may be required, particularly when dealing with rare morphs. Juveniles around 12–18 inches are ideal for adoption, as they are easier to acclimate. Prices range from $150–$300 in the U.S., with variations for morphs. These snakes are considered exotic but are widely available through specialty breeders. Always check local regulations, as some states or countries may have restrictions.
