Publean Milk Snake

Species: Pueblan Milk Snake
Scientific Name: Lampropeltis triangulum campbelli
Origin: Southern regions in Mexico. More specifically, they’re usually found throughout Puebla, hence their namesake.
Lifespan: 20+ Years
Size: Generally, the size of a Pueblan Milk Snake when fully-grown is somewhere between 24 and 48 inches in length.
Enclosure Type: The best kind of enclosure for these snakes is going to be one that opens from the front. Standard tanks that open from the top work well, too. Either way, make sure that the enclosure has a screen side or large vents. This will help to keep humidity levels under control.
Enclosure Size:  The enclosure should measure roughly 36 inches long, 24 inches deep, and 24 inches tall.
Substrate: This species prefers low to moderate humidity levels. This means a substrate material that absorbs a lot of moisture will not work well. Instead, go for something like beech woodchips. It holds onto enough moisture without raising humidity levels too high or growing mold. If you’d prefer something more natural, you can also use a soil and clay mixture. This closely resembles their natural environment in Mexico.
Décor: Natural and artificial decorations can be used sparingly throughout the enclosure. Use things like caves, cork wood pieces, and tall plants to give the snake plenty of shelter from the light. Rocks can be beneficial to Pueblan Milk Snakes. Natural slate rocks are a favorite among owners because they hold onto heat well. The snake will use the rocks to enjoy some under-belly heat.
Water: Pueblan Milk Snakes prefer to have access to spacious water bowls. This water source will most often be used for soaking. Snakes will often soak to cool off or help with shedding.
Temperature: On the cool side temperatures can get as low as 70°F. On the hot side use a basking lamp to raise temperatures to roughly 85°F. All your lights, including the basking lamp, should be on for 10 to 12 hours a day. For the rest of the time, leave things dark. These snakes are crepuscular, which means that they are active at dusk and dawn. That standard day and night cycle is paramount. At night, you still need to provide some warmth. Use an under-tank heat mat in the basking spot to keep temperatures above 80 degrees. This mat should only be on when the basking light is turned off.
Humidity: Humidity levels between 40 and 60 percent are optimal for Pueblan Milk Snakes. It’s important to consistently check and monitor those levels with a hygrometer. There’s a balance between having too must humidity and not having enough.
Lighting: You can utilize a linear UVB light of 5 to 6 percent. But it’s not necessary. Unlike other reptiles, Pueblan Milk Snakes don’t need that UVB exposure for calcium. Owners often utilize UVB lamps to support live plants instead. They can also help your snake distinguish between day and night hours when set on a timer.
Type Of Diet: Carnivorous
Types Of Food: They do best on thawed frozen mice. You can transition from small pinkies up to jumbo mice as your snake grows. As a good rule of thumb, the mice you feed should be one and half times as thick as the girthiest part of the snake’s body.
Feeding Schedule: When your snake is a juvenile, you’ll need to provide small pinkies every week. As they get older, you can pull back on frequent feedings. Adults need feeding once every other week to prevent gaining too much weight.
Supplements: No supplements are needed for a Pueblan Milk Snake.
