Clover Mite

Scientific Name: Bryobia praetiosa

Order & Family: Trombidiformes: Tetranychidae

Size: 0.75 mm - 1.0 mm (very tiny, about the size of a pinhead)

Lawns, grassy areas, and occasionally inside buildings near windows

Herbivorous; they suck juices from grasses, clovers, and various common weeds

Nuisance invaders during spring and fall; they move into homes when their outdoor habitat becomes unsuitable, but cannot survive or reproduce indoors

Harmless to humans and pets as they do not bite or transmit disease; however, they can leave red stains on surfaces if crushed
