Asian long-horned beetles arrived from China and Korea and feed upon all types of hardwoods. They seem to prefer maples but have also infected horse chestnuts in New York. Asian Long-horned beetles are not native to the U.S. and therefore have no natural enemies. Insecticides are not effective againist these pests. Infected trees are cut down and burned after adult beetles have died in late autumn or winter. Infestations have been found in Brooklyn and Amityville. If you believe that you have discovered these pests collect a sample and call your local cooperative extension or regional DEC office.
