Clover Mite

Natural Habitat

Grassy areas, lawns, and the sunny sides of buildings; often found on windowsills and walls when they enter homes.

Diet & Feeding

Herbivorous; they feed on sap from clover, grasses, and various lawn plants/shrubs.

Behavior Patterns

They are most active in spring and fall. They reproduce via parthenogenesis (females can reproduce without males) and are known for leaving a distinct reddish stain when crushed, which is their body fluid (not blood).

Risks & Benefits

They do not bite humans or pets, nor do they transmit diseases or cause structural damage. Their primary 'risk' is being a nuisance pest due to large numbers and the reddish stains they leave on fabrics and surfaces when crushed.
