Caring for Rolly Pollies (Pill Bugs)Rolly pollies, also known as pill bugs, aren't insects. They are more like shrimp, crabs, and lobsters. They need a moist environment, so put a few drops of water in. Add some rocks or dirt to let the roly pollies hide in. They like to eat lettuce, squash, carrots, apples, cardboard, paper, or a bit of chips.
