The small brown worms that are found inside houses are often millipedes. They are especially fond of basements and may live indoors year-round, although they are most common from the spring through the fall.
Millipedes are recognizable because they have many legs. Outside they live in damp habitats and are responsible for helping organic matter decay. However, if the population becomes too large or the area grows too wet, millipedes sometimes move indoors in search of a better location. They are not harmful. Millipedes neither bite nor sting, and they do not consume food or furnishings found inside the home. They also do not produce offspring if they are indoors.Learn More
