The Emerald Ash Borer and the Hemlock Woolly Adelgid (HWA) are insects invading Ash trees and Hemlock trees in Western New York and other parts of the country.  These insects are slowly sucking the life out of the trees. Hemlock Woolly Adelgid reproduces white egg sacs in the trees and when they develop, kill the trees.

The importance of Hemlock and Ash trees cannot be overemphasized. They are hugely important to the ecosystem, Hemlock provides shades and moderates the temperature. The importance of these trees to birds, other plant species and trouts is not to be ignored.

A devastating thing about these insects is that the damage done cannot be easily detected which makes it hard to control the damage.
