Invasive Pest or Disease Reporting Form

Use this form to report any suspected invasive insect or disease.

If you have questions about invasive insects, call the UNH Cooperative Extension Forestry Information Center at 1-800-444-8978.

To take pictures of a fast-moving insect, slow it down by placing it in the freezer for at least an hour before taking the picture. Upload the picture(s) below.

Store the insect in a tupperware-like container until you hear from us. We will either tell you to release the insect or give you instructions about mailing it, delivering it or arranging for pick-up.

Emerald Ash Borer
- click for details

Use this form to report a possible emerald ash borer sighting in New Hampshire. Capture and preserve the insect if possible (place in freezer or in a jar with rubbing alcohol), or provide a photo of the tree damage, insect or damaged wood. Before submitting a report, please look at signs and symptoms or these pictures of emerald ash borer insects, damage and look-alikes. Emerald ash borer infests ashes (Fraxinus species and not mountain ash). If you can, use this ash tree identification guide to verify the tree is an ash. When in doubt, upload a picture to this website.

All reports will be reviewed by our entomologists, and you may be contacted for a site visit if a follow-up is necessary.

Are you reporting a live insect? Before filing a report, compare your insect to some look-alikes.
If it isn't emerald ash borer or an ash tree, there is no need to file a report.
Are you reporting suspicious ash tree damage? Look for these signs:
