I found this heavily infested tree while hiking in the Smokies. Unfortunately, these tiny, fuzzy, white insects can kill a hemlock tree quite quickly by sucking the sap from the needles and twigs. Many areas of the park have been devastated by these non-native insects. The park staff is fighting them by releasing small predatory beetles, spraying roadside trees with a soap solution and injecting large, off-road trees with an insecticide. Unfortunately, it is too late for many of the ancient hemlocks in the higher elevations of the park.
