Millipedes are unwanted invaders found in several homes during periods of high humidity. This insect gains its name from the misguided belief that it has a thousand legs, although the largest of the species have less than 100, according to the University of California. Millipedes do not damage a home and will generally die after a few days of enduring the interior structure's drier temperatures. This does not mean that a large infestation will not cause a nuisance. They are easily controlled without the need for chemicals.
Seal any cracks in the siding, foundation or around windows to prevent millipedes from entering the home.
Remove any wet mulch, decaying vegetation or piles of leaves from around the perimeter of the home, especially any that is touching the foundation of the home. These provide ideal areas for millipedes to thrive, and these millipedes will eventually find their way into the home.
Eliminate any excess moisture from inside of your home by opening the windows or running a dehumidifier. Bathrooms and basements are the most humid areas of many homes, and are the areas most prone to millipede infestations.
Avoid over-watering your lawn and garden. The excess moisture will create an ideal environment for the millipedes to thrive.
Inspect your home for any dead millipede carcases. Millipedes generally die within one to two days of entering a home because of the lower moisture levels. Once the millipede bodies are located, remove smaller amounts by picking them up with your hands or sweeping them and discarding the millipedes in the trash. Larger amounts are more effectively removed with a vacuum.
