Species care guide
Mexican Black Kingsnake
Quick sourced reference values. LOCUS Scales' full breeding/genetics toolset is built specifically for ball pythons — this page is a courtesy reference for other species.
Scientific name
Lampropeltis nigrita (anciennement classé L. getula nigrita)
Native range
Sonoran Desert, northwestern Mexico (Sinaloa) and southern Arizona
Lifestyle
🌍 Terrestrial (active burrower, less of a climber than other kingsnakes)
The driest and most burrowing of the 3 kingsnakes on this list — unlike the California and Florida versions, humidity is almost a non-issue here. Distinctive color: deep black/dark chocolate with a blue sheen under direct light, hence the nickname "black kingsnake." Fun fact: like other kingsnakes, resistant to the venom of pit vipers native to its region thanks to natural antibodies in its blood.
Diet: Carnivore — rodents (mice), frozen-thawed. Caution: eats other snakes in the wild like all kingsnakes, never house with another snake.
Feeding frequency: Baby: every 5-7 days. Juvenile: every 7-10 days. Adult: every 10-14 days.
Substrate: Aspen shavings, in a fairly deep layer — the most burrowing-inclined of the 3 kingsnakes on this list. The driest of the three, never needs a moisture-retaining substrate.
UVB: Many breeders consider it unnecessary (nocturnal, heavily burrowing species) — but follows the same general trend as other snakes on this list: low UVB (2-5%) remains reasonable as best practice, even if more optional here than for the other 2 kingsnakes.
🏠 Enclosure size
Baby : ~20×10×10in
Sub-adult : ~30×12×12in
Adult : 36×24×12in minimum (3×2×1ft) — bigger recommended, an active species
Common questions
⚠️ Its bite can be startling — what to expect?
Same tendency as other kingsnakes — bites, chews, and hangs on for a few seconds to a few minutes rather than a quick strike-and-release. A constrictor reflex, not real aggression. Not dangerous (not venomous), decreases with acclimation.
How do I get it to release if it stays latched on?
Run the snake's head under cool (not ice-cold) tap water — the change in stimulus usually gets it to release within seconds. For a very large, stubborn animal, a bit of mouthwash (like Listerine) held near the snout (never directly in the mouth) also works.
Why does everyone talk about escaping with this species?
Like other kingsnakes, able to squeeze through openings that look impossibly small. Check every seam and lid corner before even setting the animal in.
How long should I wait after feeding before handling?
24-48 hours minimum — handling too soon after a meal increases the risk of regurgitation.
How often should I handle a new kingsnake?
Let it settle in for 5-7 days without handling after arrival. After that, short, regular sessions acclimate the animal better than long, rare ones.
