Michigan State University Extension offers resources to help people correctly identify pests—insects, weeds, plant diseases and other pests—and then choose an effective control when one is needed. Our science-based information uses Integrated Pest Management (IPM), which safeguards human and environmental health by using the least toxic methods first, up to and including pesticides when appropriate. Contact your local Extension office or MSU Pest Diagnostic Services for help in identifying a specific pest.
