A Millipede is an relatively easy Arthropod to care for. All it needs to thrive in captivity is: a plastic Kritter Keeper or other small container (it needs to be wider than it is tall), a mister bottle, potting soil, some dead-leaf litter (if you can find any; if not, that's okay), and a stick or some other hiding place. After you have your millipede home, rinse it off with water. Dry the inside and fill it with 1-3 inches of potting soil. If you were able to find dead-leaf litter, seal it in a plastic bag and place it in the freezer. Wait 48 hours. Freezing it kills off any insects or other creepy crawlies in the leaves. Spread the leaves around inside and place any sticks or other hiding places into the habitat as well. Fill the mister with de-chlorinated tap water and spray every other day or when the habitat looks dry. All done!
