Praying Mantis Housing tools: what they help with

These calculators size your praying mantis'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 praying mantis room to move, rest and behave normally.

What to know about housing and enclosure size for praying mantises

Mantises need an enclosure at least three times their body length in height so they can hang upside down to molt. A fall during molting is the single most common cause of death in captivity. Target humidity is around 50-70%.
