Hemlock Woolly Adelgid Treatment and Facts
The Facts About Hemlock Woolly Adelgid Treatment
What is the Hemlock Woolly Adelgid?
The hemlock woolly adelgid (Adelges tsugae) is a tiny aphid-like insect native to Asia. As its name suggests, the hemlock wooly adelgid feeds on hemlock trees, specifically the Carolina and Eastern hemlock. It has been found throughout the eastern United States.
Barely visible to the naked eye, the insect and its egg sacs are covered with a waxy, white "wool." The sacs, most prominent in late spring, look like the tips of small cotton swabs clinging to the base of hemlock needles.
A tree infested with the hemlock wooly adelgid can die within a few years. This serious pest has destroyed thousands of acres of trees.
The hemlock woolly adelgid feeds on the sap at the base of the host tree's needles. This disrupts the flow of nutrients, slows growth and causes the tree's dark green needles to discolor and turn grayish green, eventually falling off. Lack of nutrients causes the tree to starve to death, usually within three to ten years. It is quickest in areas where there are other pests, diseases or environmental stressors present.
Signs of Hemlock Woolly Adelgid Infestation
- The appearance of cotton tuft-like masses mostly on the underside of the foliage at the base of the hemlock's needles
- Needles that change from deep green to grayish green
