Are millipedes dangerous? Millipedes do not pose any danger to humans. However, when they feel threatened they can release a foul smelling fluid which should be washed off immediately to avoid possible skin irritation .
Millipedes are sometimes called “thousand-leggers” because of their many pairs of legs, but they actually have anywhere from 30–90+ pairs of legs, depending on the species. The leggiest is Illacme plenipes, which can have more than 333 pairs of legs.
