Millipedes are typically brown or black in color and tend to range from 1 to 2 inches in length, but some may grow larger. Their lifespan is usually around 7 years. Unlike centipedes, another arthropod they are often mistaken for, millipedes have two sets of legs for every segment of their body, and when they move, their legs appear to be moving in a wave-like motion. They do not have a thousand legs, like their name suggests, but actually have somewhere between 60 and 400. A millipede has much shorter legs than a centipede and a millipede cannot move very fast despite the number of legs they have. They are not poisonous and do not mite or sting. They spend most of their lives in the soil, but may also overwinter in leaf litter and debris found under trees.

Reasons for entering our homes:Occasionally, millipedes will make their way from their moist living conditions into homes, but will typically die because of lack of moisture and food.   During times of flooding or excessive rain, it is common for them to be found in gutters that are full of decaying matter even on second and third stories. Stemming from this what seems like an infestation can occur when they seek shelter inside the house to avoid drowning.

Diet: Most millipedes feed on breaking down or decomposing plant matter.
