Clover mites refer to very small reddish-brown mites that sometimes invade homes, especially in the early spring or late fall. Clover mites eat clover and grasses. They don't bite or transmit diseases to humans or pets, although some people may experience skin irritation from mites.
Clover mites measure about 1/30 of an inch long. They are oval-shaped and have eight legs, although the front pair of legs resembles antennae. Clover mites move slowly and typically enter on the side where the sun warms the house.
Clover mites leave a red stain when crushed, so try not to smash mites indoors. Instead, wipe mites with a wet sponge or vacuum them and then dispose of the vacuum bag elsewhere. Insecticides may be helpful outdoors, but don't use insecticides inside the house.
Prevent clover mite infestations by removing all grass and weeds within a 18- to 24-inch radius from the house's perimeter. In addition, seal cracks in the foundation with caulk and install screens on doors and windows.
