How should you take care of a roly poly bug?

Go outside and get some rich, damp, dark topsoil, and cover the bottom of a small animal tank with it. Next, take a trowel and gather leaf litter from under a tree or bush and cover the soil with it. The soil should be about an inch deep and the leaf litter about three inches. Every day spray the environment a couple times to keep it damp. Keep it in a warm, dark place in the house. Add new leaf litter every few days so it has food. When you scoop up the leaf litter, keep any organisms living in it, as long as they are not bigger than the roly poly. Make sure the lid of the container has some little holes, probably a mesh or cloth lid, so that there is continual air flow, but it is still tiny enough that any small insects in the leaf litter can't get out. The best place to get the litter and soil is where you found the roly poly in the first place. Do not keep beetles or house flies or any other bugs bigger than roly polys in the environment, just roly polys. And that's how to take care of them!
