Clover Mite

Natural Habitat

They are often found on lawns, in gardens (especially on clover), and on sun-exposed walls of buildings. They frequently enter homes through cracks around windows and doors during spring and autumn.

Diet & Feeding

Herbivorous; they feed on the sap of over 200 plant species, favoring clover, grasses, and ornamental flowers.

Behavior Patterns

They are active during cooler spring and fall weather. When crushed, they leave a distinctive red stain due to their body pigmentation. They do not bite or sting but tend to invade structures in large numbers seeking warmth or dormancy sites.

Risks & Benefits

Risks: They are a nuisance pest indoors and can stain fabrics, curtains, and walls red if crushed. They do not transmit disease, bite humans, or cause structural damage. Benefits: Minimal, primarily playing a small role in the soil food web.
