🐛 How to Set Up a Giant Millipede Habitat

A giant millipede is a calm, slow-moving pet that's genuinely easy to look after, and the heart of its care is a deep, damp bed of substrate to burrow through. Get the substrate right and the rest falls into place.

Enclosure and substrate

Millipedes are gentle, slow burrowers, so they need a tank with a secure lid and plenty of depth to dig. Give them at least 4 to 6 inches of substrate, made from coconut fiber mixed with leaf litter and bits of rotting hardwood. This isn't just bedding — millipedes burrow through it and actually eat it, so it doubles as part of their diet. Add pieces of cork bark or wood on top as hides.

Humidity

Keeping the air moist is the most important daily detail. Millipedes breathe through the sides of their bodies and dry out easily, so mist the enclosure to around 70 to 80% humidity. The substrate should feel damp but not soggy — like a wrung-out sponge. If it ever looks or feels dry, give it a good misting.

Feeding and calcium

Beyond the rotting wood and leaf litter they munch as they burrow, offer fresh vegetables and fruit. Just as important, provide a source of calcium — a piece of cuttlebone or a small pinch of calcium powder — to keep their exoskeleton strong. Remove any uneaten fresh food before it spoils.

Temperature and placement

Millipedes are comfortable at normal room temperature, so special heating usually isn't needed. Keep the enclosure out of direct sun, which can overheat the tank and dry out the substrate far too quickly.

Handling and safety

Millipedes are among the most easygoing invertebrates to handle gently, and they're completely harmless — they don't bite. There is one thing to know: many species secrete a defensive fluid when they feel threatened that can irritate skin or leave a stain. It's nothing to fear, but always wash your hands after handling and don't rub your eyes in the meantime.

It's also worth clearing up a common mix-up: a millipede is not the same as a centipede. Centipedes are faster, more aggressive, and do bite. Millipedes are the slow, round-bodied, peaceable ones — the right match for a calm pet.

With good care, giant millipedes are long-lived, often lasting several years, which makes them a rewarding, gentle choice for supervised kids.

Quick setup checklist

• Tank with a secure lid and room to burrow
• 4 to 6 inches of coconut fiber, leaf litter, and rotting hardwood
• Cork bark or wood hides on top
• Mist to around 70-80% humidity; substrate damp, not soggy
• Fresh veggies and fruit, plus calcium (cuttlebone or a pinch of powder)
• Room temperature, out of direct sun
• Wash hands after gentle handling; don't rub your eyes

🧽 Cleaning & maintenance

Keep it simple and gentle. Remove uneaten food, dead feeders, and obvious waste every few days so mold and mites cannot take hold, and pull out any moldy substrate right away. Wipe the walls and rinse the water dish as needed, and do a full substrate change every few months (more often for humid setups). Skip chemical cleaners inside the enclosure — invertebrates are very sensitive to residues — and use just hot water, with a little vinegar for the glass. For humid species, good airflow and prompt waste removal are your best defense against mold.
