Millipedes
Description:
Millipedes can range from 1/16 inch to 4 1/2 inches in length, are cylindrical and wormlike. They are usually blackish or brownish, but some red, orange or with mottled pattern. They usually have 30 to 90+ pairs of legs.
Prevention:
Reduce or eliminate the moist areas with decaying vegetation such as under trash, piles of grass clippings, flower-bed mulches, leaf litter, etc. Dethatching your lawn, mowing the lawn closely and edging it, removing piles of debris and watering your lawn in the early morning are all ways to help eliminate these unwanted pests.
