Oribatid Mites

Not much is known about these mites. They are thought to be scavengers, and are often found in soil and organic matter where they aid in the breakdown of decaying organic matter. They are also common on the twigs and foliage of trees, where they feed on algae and lichens. These mites may become a nuisance to homeowners when they congregate on or near the home (patios, roofs, plants, etc.) or enter the home. Such incidents are probably associated with a source of organic matter (leaves or moss on a roof, compost, bark, etc., in flower beds, mold on inside or outside walls, etc.). The species we encounter most commonly have wing-like, lateral extensions (pteromorphs) of the notum. This feature, plus the fact they look like "baby" ticks, distinguishes them from all other mite groups.

Control: These mites should not damage plants or the home and its contents. If mites are entering the home, finding and removing any associated organic matter should help eliminate them. In wooded areas where the organic content of the soil is high, control in some situations may not be practical or effective.
