Abstract
Millipedes and centipedes do not carry diseases that affect people, animals or plants. Millipedes do occasionally damage seedling plants by feeding on stems and leaves, and may enter homes in large numbers during periods of migration and become a considerable nuisance. They do not cause damage inside the home, although they may leave a stain if they are crushed. Centipedes, which have poison glands and can bite, pose an occasional threat to humans.
