These reddish brown to almost black mites are about 1/16 of an inch long, and sometimes appear to be much smaller. They move very slowly.

Clover mites live in turfgrass and feed on plant fluids. They do not bite people or animals. Sometimes in the spring their populations increase rapidly and mites leave the turfgrass and climb on houses, and enter through windows.

They do not infest houses. Use a vacuum cleaner to remove those that enter; wash them off the sides of the house with a water hose. Outbreaks may last only a few days.
