Damage occurs when emerald ash borer larvae feed on the inner bark, phloem, inside brands and tree trunks. Feeding on the phloem prevents nutrients and water transportation in the ash trees. If the ash is attacked, the branches can die and eventually the whole tree can as well. Ways to detect emerald ash borer infestation include seeing bark peeling off, vertical strips in the bark, seeing galleries within the tree that contain powdery substance, and D-shaped exit holes on the branches or trunk. Not all of these may be present, but these warning signs could be a good indication of possible infestation.
