Iowa Insect Notes Clover Mites Clover mites are very tiny arachnids that live and reproduce outdoors, but are frequently encountered as a household pest in early summer and in the fall when they migrate into dwellings by mistake. They vary in color from rusty brown to dark red. A distinguishing characteristic is the very long pair of front legs that extend forward like antennae as the mites crawl. Clover mites are harmless. They are an annoyance and nuisance because of their presence and tremendous numbers.
Clover mites reproduce outdoors.
Every mite seen indoors has wandered in from outside. Clover mites are plant feeders only. They feed on sap from grasses and clover, and are especially numerous in lawns with a heavy growth of succulent, well-fertilized grass. They do not cause any apparent harm to turfgrass. In some situations it may be practical to reduce migration of clover mites into the house by removing the turfgrass and leaving a bare strip 18-24 inches wide next to the foundation.
