Insect Lab

Since its inception in 1989, the Insect Lab has served thousands of Maine citizens as well as clients from throughout the region. Inquiries arrive in the form of walk-ins, phone calls, e-mails, and regular mail. The Insect Lab operates year-round and offers diagnostic services to the public, including insect identification, insect injury identification, and expert management recommendations.

The Insect Lab is part of the Pest Management Unit within the new Cooperative Extension Diagnostic and Research Laboratory.

Important Notice:
