If you think you've seen the emerald ash borer (EAB) or ash tree damage caused by an infestation, please complete the form below. Or if you prefer to make a report by phone, please call 1-866-322-4512. If you have a digital camera, take pictures of the insect and the damage to your ash trees. If possible, place an adult in a container and freeze it, and any larvae in a container with rubbing alcohol, to help with identification.
