About the Milk Snake

Milk snakes, part of the Lampropeltis genus like the King snake, are one of the more misunderstood creatures in North and Central America. Despite their sometimes startling appearance, which often leads people to confuse them with the venomous coral snake, milk snakes are harmless and, in fact, are frequently kept as pets due to their generally docile temperament and ease of care.


Milk snakes can vary in size depending on the subspecies, but most adult milk snakes found in the pet trade fall between 2 to 4 feet in length. As juveniles, they are slender and delicate but grow to become more robust and muscular adults. The length and girth of the snake can also depend on factors like diet, genetics, and overall health.

Unique Features

The vibrant color bands of red, black, and white or yellow make the milk snake particularly eye-catching. This coloration not only aids in their camouflage amidst leaf litter but also acts as a form of Batesian mimicry, where the harmless milk snake appears similar to the venomous coral snake, thereby deterring potential predators. The saying “Red touches yellow, deadly fellow; red touches black, venom lack” is a common rhyme used to differentiate between the two, though it’s crucial to note that this doesn’t always apply outside of North America.

Behavior and Temperament

Milk snakes are typically docile, making them suitable for beginners in snake keeping. They can be curious, often exploring their enclosures, especially during the dusk and dawn hours when they are most active. While younger milk snakes might be a bit more skittish, with regular, gentle handling, they usually grow to become more tolerant and even-tempered as they age.


When it comes to handling milk snakes, patience and regularity are essential. Start with short sessions, especially with younger snakes, and avoid any sudden or jerky movements. With time, the snake will become more accustomed to human interaction. However, it’s essential to avoid handling shortly after feeding or when the snake is in its shedding phase to reduce stress.

Diet & Nutrition

In the wild, milk snakes have a varied carnivorous diet that might include smaller reptiles, amphibians, and even bird eggs. In captivity, their primary diet consists of appropriately-sized mice. Juvenile milk snakes might benefit from more frequent feedings, roughly every 5-7 days, whereas mature snakes can be fed once every 7-10 days.


Maintaining an optimal temperature gradient is crucial for the well-being of milk snakes. The warm end of their enclosure should hover between 82-88°F (28-31°C), while the cooler side should be around 70-75°F (21-24°C). Using under-tank heaters or basking lamps can help achieve these temperatures.


For milk snakes, a humidity level ranging between 40-60% is appropriate. It might be beneficial to slightly increase the humidity during their shedding phase, aiding in a smoother shedding process. A humidity box or occasional misting can prove helpful in maintaining these levels.


While milk snakes don’t require specialized UVB lighting, maintaining a consistent 12-hour light/dark cycle can be beneficial for their internal rhythms. Ambient room lighting is usually sufficient, but if using artificial lighting, it shouldn’t be too intense or disruptive.

Common Health Issues

While milk snakes are hardy creatures, they are susceptible to some health concerns. Respiratory infections, mites, internal parasites, and shedding issues are among the common health problems. Regular observation and annual check-ups with a reptile-savvy veterinarian can help ensure your snake remains healthy.


Breeding milk snakes requires a deep understanding of their seasonal reproductive cycles. After a winter cooling or brumation period, the snakes are ready to breed. Post-mating, the female will lay a clutch of eggs, requiring controlled temperature and humidity levels to incubate successfully.

Mating Habits

During the mating season, male milk snakes can become more restless, actively seeking out females. Upon finding a receptive female, the male will employ courtship behaviors, including body rubbing and tongue flicking. After successful mating, females will lay their eggs roughly a month later. Proper understanding and care during this time are vital for successful breeding.
