Choose a secure enclosure
Use a sturdy glass or plastic enclosure with a close-fitting, ventilated lid. African land snails are strong climbers and an open or poorly fitted top quickly becomes an escape route.
Wooden enclosures are unsuitable because damp conditions make them difficult to keep hygienic, and damaged or chewed wood can splinter. Position the tank away from direct sunlight, radiators, draughts, aerosols, household cleaners and insecticides.
Allow enough usable space
The Royal Veterinary College and RSPCA use 60 × 45 × 40 cm as a minimum reference for two giant African land snails. The right enclosure still depends on the adult size and number of snails, so larger animals or groups need more room.
Floor space matters, but the enclosure also needs enough height for a useful substrate layer without leaving a dangerous drop from the lid. Heavy, hard decorations should not sit where a snail could fall onto them.
Use a safe, damp substrate
Use a suitable chemical-free soil or peat-substitute substrate that holds moisture and allows burrowing. Published minimum-depth guidance varies, but 4–6 cm is a sensible starting point for many commonly kept giant African land snails; deeper substrate may be appropriate for larger animals and normal burrowing behaviour.
Keep it damp rather than saturated. Avoid garden soil, fertilised compost, soil containing wetting agents, sharp gravel, sand, bark chips and scented or treated products. If a product does not clearly state what it contains, do not assume it is safe.
Add simple, low-risk furnishings
Provide at least one hide and visual cover. Cork bark, moss and lightweight plant pots can work when clean and safely positioned. Choose items without sharp edges, exposed metal, paint, pesticide residue or small gaps that could trap a growing snail.
A very shallow, stable water dish may support drinking and humidity. Keep the water only a few millimetres deep and change it daily. Provide a separate cuttlefish bone as a continuous calcium source.

Test before arrival
Run the completed enclosure for several days. Record the warmest, coolest, driest and most humid readings rather than relying on a single spot check. Adjust ventilation, misting and thermostatically controlled heating gradually.
The enclosure should be stable before a live animal depends on it. Our temperature and humidity guide explains the broad reference ranges and why the exact species still matters.
