from 5 to 10 years if u have female and male u should have big tank cause the female lays thousands of egg in one place
They normally live and die in the same year. If your thinking of a composting box don't worry they normally producible 60 to 80 kids per mate.
As long as it takes them to die! ;) Hope that helped.
They live 2-4 years in the wild, in captivity they can live to 10 years.
