Distribution and habitat

The predominantly nocturnal, ground-dwelling Durango king snakes are found exclusively (endemically) in the Durango Mountains in the Mexican state of Durango, where they live in dry steppes and fertile plateaus, often near fields and plantations.


Minimum dimensions for the terrarium, according to the size and number of animals:

1-2 animals 1KL x 0,5KL x 0,5KL (L x W x H)

Body length (KL) is measured on the largest animal. For each additional animal the floor space should be increased by 20%. A terrarium of e.g. L 100 x W 60 x H 60 cm is recommended, which should be placed in a quiet and vibration-free place.

They need a terrarium structured with roots, stones and cork tubes (hiding places and visual protection) with a graveable substrate, e.g. of sand-humus mixture with peat and foliage, as well as an easy to clean water basin as drinking vessel. To ensure constant humidity, a small portion of the substrate must always be kept slightly moist, for which sheets of sphagnum moss are well suited. Once a day, preferably in the evening, the inside of the terrarium should be finely sprayed with water. A rain or mist system is ideal

Temp. day: 24-28 °C Temp. night: 18-24 °C Temp. local: up to 32 °C Humidity: 50-70

Thermostatically controlled floor heating is recommended. Lighting duration must be 12-14 hrs. depending on the season. Daylight fluorescent tubes supplemented with UV lamps are ideal.


The food supply consists of live rodents (e.g. mice, rats) according to their size. After successful acclimation, the changeover to dead food animals (commercially available frozen food) is often successful. Juveniles should be offered food every 3-5 days, adults every 7-14 days, with occasional periods of fasting (e.g., skipping a feeding). If the snake is disturbed after feeding, this may result in vomiting of the prey. It is better to offer several small feeders, rather than one large one. If it does not eat for a long period of time, both the timing and the food should be varied. It is important to fortify the food animals with vitamins and minerals. Since the snake could be injured by live rodents, it should not be left unattended with them.

Reproduction and breeding

Probing by the veterinarian is the only reliable method of sex determination.

A resting period is recommended for successful reproduction. The female lays her eggs (4-10 eggs) in the moist substrate about 5 cm deep and does not perform brood care. The incubation period is 55-60 days at a temperature of 28 °C. The young are 15-17 cm in size and can be fed with nest young mice.


They come in different color variations and are mostly docile

Socialization is not recommended, as they eat conspecifics and other snakes, including venomous ones. They need a sunny place warmed by radiators.

A resting period of 3-4 months at a temperature of 8-12 °C accompanied by a feeding break is recommended.

Always have snake hooks and protective gloves ready when handling.The terrarium must have good ventilation without drafts and meet the species-specific needs. Measuring devices such as thermometers, hygrometers, etc. are necessary. The lighting has to correspond to the species-specific day-night rhythm and has to be placed in such a way that the animals cannot injure themselves. The terrarium should be locked in such a way that neither unauthorized persons can open it nor the animals can escape. Contamination must be removed regularly
