Massachusetts Introduced Pests Outreach Project
Asian Longhorned Beetle Report

Use this form to report a possible Asian longhorned beetle sighting in Massachusetts or other states. Capture and preserve the insect if possible (place in freezer or in a jar with rubbing alcohol), or provide a photo of the insect or damaged wood. Before submitting a report, please review our fact sheet for photos and a description of this invasive pest.

All reports will be investigated, and you may be contacted by a state inspector for a site visit if a follow-up is necessary. We thank you for your assistance with preventing the further spread of Asian longhorned beetle in our state.
