Clover Mites

Clover mites are very tiny, smaller than the head of a pin and reddish brown. They do not bite. Clover mites live primarily in lawns and feed on grasses and plants but do not damage them. Newer lawns and new home sites seem to develop the highest populations. Eventually, clover mite populations stabilize. Old lawns sometimes produce a mite problem when the lawns decline and are then heavily fertilized. Clover mites are usually most noticeable in the spring when temperatures are between 45° and 80°F and the humidity is high. On warm days they cross the grass and crawl up the sunny sides of buildings. They enter homes through cracks around window and door frames or any other crack that eventually opens into the house. They are small enough to pass through window screens.

Management

To control Clover mites, use weather stripping to tighten windows and doors and caulk any cracks. Vacuum up any mites that make it indoors.
