Raise chickens. If you have the space, energy, time, and resources, consider raising chickens on your property. Chickens are a rather unconventional method of getting rid of millipedes, but they are a natural predator and can keep your millipede population under control for the duration of their lives.
Chickens have a rather large appetite; a few chickens can take care of most moderate infestations.
Only consider this option if you are zoned to care for chickens and if you know that you are
ready for the responsibility of caring for chickens.
