Clover Mites
Scientific Name: Bryobia praetiosa
Order & Family: Trombidiformes, Tetranychidae
Size: Around 0.75 mm (less than 1/32 of an inch)

Natural Habitat
Outdoors, they lay eggs in cracks and crevices, usually on objects in direct contact with the ground. Indoors, they may be found around windows, walls, and sometimes on furniture, especially during changes in weather when they seek shelter.
Diet & Feeding
Plant feeders, primarily feeding on clover, grasses, and other common plants. They get their reddish color from the plant pigments they ingest.
Behavior Patterns
Clover mites are known for migrating into homes in large numbers, often in the spring or fall when outdoor conditions change. They do not bite humans or animals. When crushed, they leave a red stain.
Risks & Benefits
Potential risks include being a nuisance pest when they invade homes in large numbers and leaving red stains if crushed. They do not transmit diseases, bite, or cause structural damage. There are no significant benefits to humans beyond their role in the ecosystem as herbivores.
