Look Out For Fall Millipede Migrations!

By Chris Williams on October 15, 2012.

In fall, and sometimes in spring, millipedes occasionally migrate by the thousands, and can end up inside your home. What triggers these migrations? Our best guess is that it’s a combination of temperature and humidity. Millipedes like secluded damp areas where they can feed on decaying plant material. If their environment becomes too dry or too wet, they either move on or die. Unfortunately, when they move on, it is often into your home. Because millipedes require moisture, once indoors they gravitate toward the dampest areas of the house, almost always on the lowest level. They can be found in crawlspaces, basements, Get rid of Millipedesnear washing machines and sump pumps. Millipedes are mostly harmless. They don’t bite, they don’t damage household furnishings, but they can excrete a strong-smelling defensive fluid if they’re handled. The fluid from some species can irritate the skin and eyes on contact. Millipedes don’t usually survive long inside because of the lack of moisture and they can be easily removed with a vacuum or broom. Because millipedes are so dependent on damp conditions, drying out their outside environment is a pesticide-free way to control them around the outside of your house. The more you can eliminate moisture around the foundation of your home, the fewer millipedes you will have. These tips work for other moisture-loving foundation pests, too, like crickets, sowbugs, and earwigs. Dry

1) Remove debris around the foundation

Mowing your lawn regularly helps remove millipedes.3) Mow lawns more closely and edge lawns

This allows the grass to dry more quickly and reduces millipede habitat. Some kinds insects can be helpful to your lawn and should not be removed.

4) Water in early morning

Watering first thing in the morning allows the grass to dry during the day instead of remaining wet though the night.

5) Create a vegetation-free barrier

Rake back mulch and/or remove thick grass and plants within 6-12 inches of the building perimeter. If you have to mulch around your foundation, use as light a layer as possible. Keeping millipedes away from your home’s foundation means fewer will find their way inside through gaps around doors or utility lines, or through foundation vents and other openings. Don’t forget to caulk and seal openings around the foundation and be sure that the gasket at the bottom of your garage door seals tightly.
