Predatory mites can be distinguished from pest mites by observing their movement. When disturbed, predators generally move more quickly than pest mites. A ratio of one predator to 10 pest mites is often sufficient for effective biological control.
The MSU IPM Program maintains this site as an access point to pest management information at MSU. The IPM Program is administered within the Department of Entomology, fueled by research from the AgBioResearch, delivered to citizens through MSU Extension, and proud to be a part of Project GREEEN.
