Do Nuevo leon king snakes make good pets?

Nuevo leon king snake, Lampropeltis mexicana thayeri are a beautifully marked species of king snake originating from the Mexican plateaus in Tamaulipas, Mexico. As with most snakes, hatchlings of this species can be a little skittish and defensive, but they tame down easily enough when the time is spent with them, making them not a bad option for beginner snake keepers.

All of the Nuevo leon king snakes for sale at Swell Reptiles were captive bred in the UK, so you can rest assured that your new snake came from a reliable source. King snakes are cannibalistic, and naturally predate on other snakes, so they should always be kept individually to avoid an inevitable confrontation that will likely lead to the death and even consumption of one individual.

What size vivarium does a Nuevo leon king snake need?

Nuevo leon king snakes are very inquisitive and active, so should be provided with plenty of space to roam and fill with enrichment. We recommend a minimum enclosure size of 120 x 60 x 60cm (4 x 2 x 2ft) for this species, which makes the VivExotic Repti-Home Bearded Dragon Vivarium Large a great option. Wooden vivariums such as this usually work best due to holding in the heat better, but PVC and glass enclosures are also suitable.

What temperature do Nuevo leon king snakes need?

Nuevo leon king snakes are ectothermic, so cannot control their own internal body temperature and rely on external heat sources to do this. Therefore, their captive enclosures should have a temperature gradient that runs from warm in one end to cool in the other.

The ideal basking temperature for this species is 30-32°C (86-89°F), with a cool end temperature between 22-25°C (71-77°F). The best way to achieve this in the larger set-ups required by this species is by using an overhead heating system such as a basking lamp and dimming thermostat, or a ceramic heater and pulse thermostat.
