Appearance: Blackish or brownish, some red, orange or with mottled patterns. Long, cylindrical and worm-like.

Habitat: Millipedes are found throughout the world, with about 1,000 species occurring in the United States alone. They are typically found in areas of high moisture and decaying vegetation, such as under trash, in piles of grass clippings, flower-bed mulches, piles of leaves, etc. Millipedes do not usually survive indoors for more than a few days unless there are high moisture conditions and a food supply is present.

Potential Harm: Some millipede species give off an ill-smelling fluid through openings along the sides of the body. In some instances, this fluid can be toxic to small animals and pets, and can cause small blisters on humans.
