Kenyan sand boa care guide

Eryx colubrinus

A small burrowing boa that spends most of its life under the substrate. Depth matters far more than height.

Fossorial — deep substrate for burrowing

Kenyan sand boa enclosure size

Fossorial — deep substrate for burrowing. An adult kenyan sand boa should live in at least 36" L × 18" W × 12" H; we build toward 48" L × 24" W × 16" H (4 × 2 × 1.3 ft, roughly 8 sq ft of floor and about a 80-gallon glass equivalent).

Females are much larger than males and use the extra floor space.

Hatchling / baby
24" L × 12" W × 12" H recommended · min 18" L × 12" W × 8" H
Juvenile
30" L × 18" W × 12" H recommended · min 24" L × 12" W × 12" H
Adult
48" L × 24" W × 16" H recommended · min 36" L × 18" W × 12" H

Temperature and heating

Overhead halogen or a belly heat source on a thermostat, warming one third of the floor only.

Basking / warm surface
95°F warm surface
Warm side (ambient)
88–92°F substrate on the warm third
Cool side (ambient)
75–80°F
Night
72–78°F

Lighting and UVB

UVB: Optional low-output T5 UVB 5% (UVI 1–2). Run lights on a 12 hours photoperiod, on a timer, and replace UVB bulbs on the manufacturer's schedule even while they still emit visible light.

Humidity

Target 30–40%. Dry substrate with a small humid hide during sheds — wet bedding causes scale rot.

Substrate and depth

Aspen or a sand/soil blend that holds a tunnel. Depth: 4–6 in.

Enclosure tips and furnishing

  • Deep diggable substrate
  • One or two hides on the surface
  • Flat rock over the warm zone
  • Small water dish

Build list

  • 36x18 footprint tub or terrarium — Floor area over height — they never climb.
  • Thermostatted heat source — Belly heat drives their digestion.
  • Digital thermostat — Every heat source must run through a thermostat — unregulated heat burns animals.
  • Two digital probe thermometers + hygrometer — Read the warm side, cool side and humidity directly — stick-on dials are inaccurate.
  • Bulk aspen or sand/soil blend — Burrowing depth is the whole enclosure for this species.

Kenyan sand boa FAQ

How big should an adult Kenyan sand boa enclosure be?

At least 36" L × 18" W × 12" H, and we recommend building to 48" L × 24" W × 16" H — about 4 × 2 × 1.3 ft, or a 80-gallon glass equivalent. Fossorial — deep substrate for burrowing.

What temperatures does a Kenyan sand boa need?

Basking or warm surface 95°F warm surface, warm side 88–92°F substrate on the warm third, cool side 75–80°F, night 72–78°F. Overhead halogen or a belly heat source on a thermostat, warming one third of the floor only.

Does a Kenyan sand boa need UVB?

Optional low-output T5 UVB 5% (UVI 1–2). Photoperiod: 12 hours.

What humidity does a Kenyan sand boa need?

30–40%. Dry substrate with a small humid hide during sheds — wet bedding causes scale rot.

What substrate is best for a Kenyan sand boa?

Aspen or a sand/soil blend that holds a tunnel, at a depth of 4–6 in.

How big does a Kenyan sand boa enclosure need to be for a hatchling?

Hatchling / baby: 24" L × 12" W × 12" H recommended, minimum 18" L × 12" W × 8" H. Scale up to the adult footprint as the animal grows.
