Clover Mites
Overview
Clover mites sometimes invade homes in enormous numbers, in early spring and late autumn, overrunning floors, walls, drapes, window sills and furniture, even occasionally getting into beds and clothing. They may become troublesome in hospitals, nursing homes, apartments, food processing facilities, etc. If crushed, they leave a reddish stain quite noticeable on linens, curtains, walls and woodwork. They are a nuisance by their presence but do not bite humans or animals, transmit disease nor feed on household furnishings or pantry supplies. Skin irritation may be caused in sensitive persons. They live outdoors feeding on various plants.
Clover mites are about 1/30 inch long (smaller than a pinhead), oval-shaped arachnids, reddish-brown to olive to pale orange or sometimes green-brown after feeding. They are eight-legged with the front pair of legs very long, protruding forward at the head. These front legs are sometimes mistaken as antennae or feelers. There are featherlike plates on the body and fan-shaped like hairs along the back edge of the body when viewed under a magnifying glass. Young are smaller and bright red. Also, eggs are bright red. Crawling mites are sluggish, slow-moving and normally invade the home where the sun is warmest at south, southwest and east side of the house.
