Clover Mite
Scientific Name: Bryobia praetiosa
Order & Family: Acari (mite subclass) / Tetranychidae (part of the "spider mite" family, though sometimes placed in different families depending on classification, e.g., Bryobiidae or Trombidiidae for some red mites). For general purposes, 'Acari' for order and often just referred to as a 'mite' rather than a specific insect order.
Size: Approximately 0.75 mm - 0.85 mm (about 1/30 inch)
Natural Habitat
Primarily outdoor pests, found in lawns, gardens, and around the foundations of homes. They may invade homes, especially in spring and fall, seeking shelter or moisture. Often found on sunny walls and window sills.
Diet & Feeding
Clover mites feed on a wide variety of plants, including clovers, grasses, and many other lawn and garden plants. They pierce plant cells and suck out the chlorophyll.
Behavior Patterns
Clover mites are most active in cooler temperatures of spring and fall. They often congregate on sunny sides of buildings. They tend to invade homes when vegetation around the foundation dries out or is removed. They leave red stains when crushed.
Risks & Benefits
Clover mites are considered nuisance pests. They do not bite humans or pets, nor do they transmit diseases. They are not known to cause structural damage to homes. The primary risk is the red staining they leave behind when crushed on light-colored surfaces like walls, furniture, or curtains. They can cause minor damage to plants but are generally not a severe agricultural pest.
