Millipedes are approximately 1 to 1 1/2 inch in length. They are brown in color and have a hard, worm-like body lined with legs. This many legged arthropod has two pairs of legs attached to each segment on its body. While millipedes do not bite and are generally considered to be a low-risk pest, a sudden swarm of these insects can lead to odors, stains, and other annoyances.
Millipedes do not leave behind many signs to let you know that you have an infestation. The only real sign is to find the pests themselves. A millipede must have extremely high humidity levels to live. Lowering the humidity in your home will help make it much less attractive to millipedes. Additionally, seal all possible entry points that the pests could use to get into your home and clean your yard of decaying wood, grass, and leaves.
