Concrete Mite

Look Before You Sit on Concrete

We're seeing large numbers of tiny, fast-moving bright red mites scurrying around on sunny surfaces such as on picnic tables, patios, sidewalks, concrete retaining walls, and on the outside walls of homes and buildings in southern Ohio. These nuisance mites belong to the genus Balaustium (family Erythraeidae) and are sometimes called "concrete mites" owing to locations where they tend to congregate.
