Most mantises have relatively short livespans—only about six months, from spring to early fall. In the fall, females lay an egg case containing hundreds of eggs in a sheltered location, from which baby mantis nymphs hatch in the spring. The nymphs spend the summer eating, growing, and breeding to eventually repeat the cycle.
They may survive for a little while indoors, but due to lack of food and their naturally short lifespans, they’re unlikely to make it through winter.
