Clover Mite

Natural Habitat

Typically found in grassy lawns, clover-rich turf, and near building foundations; they often migrate indoors through windows and doors.

Diet & Feeding

Plant sap; they feed on over 200 species of plants, including lawn grasses, clover, ornamental flowers, and shrubs.

Behavior Patterns

They are most active during the spring and fall when temperatures are cool. They reproduce parthenogenetically (females produce eggs without mating), and their populations can explode quickly under favorable conditions.

Risks & Benefits

They do not bite humans or pets and do not transmit diseases. They are considered a nuisance pest because they leave a reddish-brown stain if crushed on surfaces like carpets or curtains. They play a role in the ecosystem as herbivores but are generally unwanted in home environments.
