Wooden vivariums are the best enclosures for milk snakes. As its an excellent heat insulator, it’s can control the temperature variation within the housing. Make sure that the wooden cabinets have sufficient ventilation for the air to flow inside freely.

Young ones require a cage size of 10 gallons. Adult species need an enclosure of 20 – 70 gallons. On average, it’s advisable to maintain a length of 34” as they quickly grew in length. These reptiles are great escape creatures. So make sure that the screen top is secure at all times. Never keep more than one snake together as they can turn cannibalistic.

Temperature, Heat, and Lighting

Just like every other reptile, milk snakes also require a thermal gradient. During the daytime, they need a warm basking spot. This is possible by placing a bright spot bulb at one corner of the enclosure. The basking temperature needs to be between 85 – 90°F. Or else it can be detrimental to their wellbeing. For this, you can use a basking light of 40 W in a 3 ft cage.

During night time, they need daughter darkness with a drop in temperature levels. You can switch off the basking light at night. Maintain 80°F at night by using ceramic heat emitters or heat mats.

These heating items release heat without radiating any light. By using a thermostat, you can control the temperature of the heat mat. Monitor the temperature in the enclosure using the thermometer daily. 

Eastern Milk Snake Feeding

Milk snakes usually feed on rats and mice. Based on the girth of the reptile, the size of the prey varies. Make sure that you do not feed them with anything larger than the thickest area of their body. You will find that the prey item leaves a noticeable lump in their belly. This is a common sight for most species. 

Hatchlings are mostly fed every five days. As for the adult creatures, you can feed them every 10 days. Some pet keepers feed the adult species only once in two weeks as they become overweight.

Pre killed frozen prey or live prey can seem to be a question. Options may vary, but thawed frozen mice are the best choice. 

Thawed rodents are easier to feed and less expensive. Also, you can buy them in bulk and store them in your cooler. More significantly, it is safer for your reptile as they won’t hurt your pet for defensive reasons. 

It’s essential to give high-quality prey coated with vitamin supplements. Calcium powders and vitamins are necessary for their overall health. 


Place a large water bowl in the cool end of the housing. Make sure that the container is big enough for them to soak themselves. However, they shouldn’t be too large that they will find it difficult to get out. Clean and refill the water daily to avoid microbes from growing.

Incubate the eggs using an incubator at a temperature of 84°F. The eggs are usually incubated in sealed containers with moist substrates like Hatchrite. This helps in trapping the eggs with a sufficient amount of humidity. After 60 days, the eggs start hatching. The first set of babies that emerge will promote the other eggs to hatch as well.
