Common Questions

What is the Hemlock Wooly Adelgid?

HWA (Adelges tsugae) is an invasive exotic insect that attaches to the base of the needles and feeds upon essential nutrients, eventually killing the tree. It attacks the Eastern and Carolina Hemlock (Tsuga canadensis and Tsuga caroliniana), which are both abundant in this area. The Hemlock Woolly Adelgid has attacked trees in East TN since 2002. All East Tennessee Counties currently have infestations. If infested trees are left untreated they will almost certainly die.
