This was posted from another member awhile back:.
most millipedes protect themselves with a cyanide compound. To be safe you should not feed millipedes to any animal.
From Wikipedia: "Many species also emit poisonous liquid secretions or hydrogen cyanide gas through microscopic pores along the sides of their bodies as a secondary defense.[7][8][9] Some of these substances are caustic and can burn the exoskeleton of ants and other insect predators, and the skin and eyes of larger predators."
They do harm animals when eaten. They can harm plants. I've seen scorpions eat them, but not many other things seems to like them.
