Although clover mites are not a danger to human health and do not destroy furniture, clothing or food items, they can become an indoor nuisance when invading homes, business and medical facilities. Once inside, they will soon die, but not until they have created problems resulting from an annoying presence and cosmetic damage from red stains resulting from mites that are crushed.

This stain is not the mite’s blood, but is the mite’s body pigments. Clover mites are not blood feeders, but feed on plants getting their nutrition from sucking plant juices from grasses, clover and other plants common to lawns. Clover mites can become a nuisance in multi-story buildings since they can live on rooftops and patios where mold or mildew provide sources of food.
