Rolly pollies

Rolly pollies look like a miniature armadillo that rolls up into a ball when disturbed. The scientific name of their family is “Armadillidiidae,” for obvious reasons. While often thought of as pests, they are actually rarely harmful to plants. They mainly feed on decaying matter on the soil surface. However on occasion, they feed on young, seedlings. Discourage them by sprinkling washed and crushed eggshells, corn meal or diatomaceous earth around the base of your seedlings.

People are surprised to learn that rolly pollies are not insects, rather they are crustaceans. They are related to shrimp and crayfish, breathe with gills, and need humidity or moisture to survive.
