An Update on Hemlock Woolly Adelgid & Emerald Ash Borer

Emerald Ash Borer (EAB) and Hemlock Woolly Adelgid (HWA) are two invasive non-native insects that are changing the face of our forests. EAB feeds only on ash trees, killing them quickly, and is rapidly spreading through the area creating many economic challenges for individuals and communities needing to deal with the death of these common trees. HWA is spreading more slowly and takes years to kill hemlocks, but mortality is mounting.
