Grey-banded Kingsnake Caresheet


Background Information
Grey-banded Kingsnakes are a colubrid snake native to the Trans-Pecos desert in Western Texas and Southern Mexico. Growing up to 4ft long, it is considered a moderate sized species. However, the average tends to be about 3ft, females often growing slightly larger than males. Due to its secretive nature and the harsh environment it originates from, the rarity of this species in the wild have made herpetologists consider it endangered in some areas. With nice patternings and a docile nature compared to other kingsnakes, bites are not common allowing this species to be a nice starter as well as one for a collection.

Captive Requirements and Welfare
Kingsnakes are known to be ophiophagus (meaning “snake-eater”) therefore housing them singly is mandatory to avoid any complications. In the wild this species burrows through the majority of the day to escape the heat so a substrate should be given to accommodate this behaviour.

2 at minimum: one on each side a 3rd moss hide during shedding would be beneficial


Branches and fake plants allow the opportunity to climb and aids shedding


Fresh water topped up when needed clean out water bowl every few days to prevent slime build up

Food (Feeding)

Pinkies for hatchlings then increase the size as they grow. Always take the snake out and feed in a separate box to prevent substrate being eaten.


Spot pick weekly, full clean monthly
