hwa_damageOften seen as white cottony masses on the undersides of the twigs of Canadian and Carolina hemlocks, this small aphid-like pest is a serious threat to our beautiful native hemlock trees.

If left untreated, the damage begins to show as stunted, yellow growth at the tips of the branches, eventually killing off the entire branch, and spreading throughout the tree.

Several different treatment options are available, and are most effective when applied before the tree starts showing signs of decline.
