Clover Mites Identification Guide

Physical Characteristics

Clover mites are tiny, reddish-brown arachnids that measure less than 1 millimeter in length. They have long front legs that extend forward, resembling antennae, and an oval-shaped body. When crushed, they leave behind red stains, which can be a nuisance for homeowners. They do not bite humans or pets but can invade homes in large numbers, particularly in the spring and fall.

Common Species

Bryobia praetiosa (Common Clover Mite)

Clover Mites Behavior and Biology

Clover mites reproduce parthenogenetically, meaning all individuals are female and can lay eggs without mating. Their eggs are often deposited in protected areas such as cracks in building foundations or under tree bark. They thrive in well-maintained lawns with ample moisture and can migrate indoors in search of warmth during seasonal transitions.

How We Treat for Clover Mites

Clover mites are attracted to moisture and often enter homes through small cracks and openings around windows, doors, and foundations. Our treatment approach includes:

  • Addressing moisture issues: Identifying and reducing excess moisture in basements or crawl spaces.

  • Perimeter treatment: Applying a mosquito spray treatment around the home’s exterior, focusing on a 1-2 foot barrier to prevent mites from entering.

  • Vacuuming: Removing visible mites inside the home to reduce their numbers without causing staining.

  • Focus on sunny areas: Since clover mites prefer warm surfaces, we concentrate treatments on the sunny sides of homes where they are most active.
