Clover Mite

Natural Habitat

Typically found in grassy lawns with rich soil; often migrates into buildings through cracks around windows and doors during spring and autumn.

Diet & Feeding

Strictly herbivorous; feeds on the sap of over 200 different plant species, including grasses, clover, ivy, and common ornamental shrubs.

Behavior Patterns

Active during cooler months (spring and fall). They are known for their very long front legs, which are often mistaken for antennae. They reproduce parthenogenetically, meaning females can lay viable eggs without mating.

Risks & Benefits

They do not bite humans or pets and do not transmit disease. They are considered a nuisance pest because they can leave a red stain if crushed on indoor surfaces (fabrics or walls), which is caused by their body pigments, not blood.
