Kenyan Sand Boa Care: The Complete Guide

TL;DR: Kenyan sand boas (Eryx colubrinus) are small, docile burrowing snakes — females reach 24–32 inches, males only 15–20 inches — with a lifespan of 15–20+ years in captivity, making them excellent beginner snakes. Their defining care requirement is 4–6 inches (ideally 8+ for females) of loose substrate such as aspen shavings to allow burrowing, their natural hunting and resting behavior. Warm-side surface temperatures should reach 88–95°F, maintained with an under-tank heat mat on a thermostat.

The Kenyan sand boa (Eryx colubrinus) is one of the hobby's most underappreciated gems. Small (18-30 inches for most females; males are much smaller at 15-20 inches), docile, and endlessly interesting, sand boas are burrowing snakes from the semi-arid regions of East Africa. They spend most of their time underground with just their head exposed -- a fascinating hunting adaptation.

They are hardy, low-maintenance, and excellent for beginners. The only unusual aspect of their care is their need for deep, loose substrate to burrow in.

Quick Facts: Kenyan Sand Boa

Housing

Kenyan sand boas are small snakes with modest space requirements:

• Males: 10-gallon tank or 16-qt tub adequate for life
• Females: 20-gallon long or 28-40 qt tub

Plastic storage tubs with drilled ventilation are popular among keepers -- they hold heat and substrate depth well. A 20-gallon long tank with a secure screen lid also works.

Temperature

Kenyan sand boas are from semi-arid East Africa and need warm temperatures:

• Warm side surface (basking zone): 88-95 degrees F
• Ambient warm side: 80-85 degrees F
• Cool side: 70-75 degrees F
• Night: Can drop to 65 degrees F

Use an under-tank heat mat connected to a thermostat on the warm side. Deep substrate does reduce heat penetration -- verify temperatures at substrate surface level using an infrared temp gun.

Substrate: Deep is Key

This is the defining feature of sand boa care. They must burrow -- it's a core behavioral and physiological need. Provide 4-6 inches of substrate minimum (8+ inches is better for females):

• Aspen shavings -- dry, lightweight, easy to burrow through; excellent
• Play sand mixed with aspen -- more naturalistic
• Dry topsoil -- good for burrowing

Keep substrate DRY. Sand boas are from arid environments and high humidity causes respiratory and skin issues. Humidity target: 30-50%.

Feeding

Kenyan sand boas eat frozen/thawed rodents (never live):

• Males: Pinky to small mice throughout life
• Juveniles: Fuzzy mice
• Adult females: Adult mice every 7-14 days

Use feeding tongs to offer prey near the surface of the substrate -- they'll ambush it from below. Frequency: every 7 days for juveniles; every 10-14 days for adults.

Handling

Kenyan sand boas are docile and easy to handle. Wait 48-72 hours after feeding. They may musk when first picked up but quickly calm down. With regular handling they become very relaxed.

Common Health Issues

• Respiratory infection: From excess humidity; keep substrate dry
• Retained shed: Increase humidity slightly during shed (brief humid hide)
• Obesity: Very easy to overfeed -- especially females. Keep prey size appropriate.
