Millipede Housing tools: what they help with

These calculators size your millipede's living space: the minimum and recommended dimensions, how much bedding or substrate to buy and what fits in the space you have. Too little space is one of the most common welfare problems in pets. The right size gives a millipede room to move, rest and behave normally.

What to know about housing and enclosure size for millipedes

Millipedes need deep substrate rich in rotting hardwood and leaf litter, which is their actual food rather than an addition to it. They secrete a defensive fluid that can stain and irritate, so wash hands after handling. Target humidity is around 70-85%.

Treat the minimum as the floor, not the goal. Bigger is almost always better, especially for active or social species.
