Below, we outline how we identify and treat hemlock woolly adelgid:

Identifying Hemlock Woolly Adelgids

The hemlock woolly adelgid (HWA) is a non-native pest that feeds on hemlock trees’ fluid. Although the individual bugs are small, a swarm can cause significant harm. Early signs of infestation include thinning, fading, and dying limbs at the base of the tree. 

That said, the woolly masses are the most obvious symptom of an infestation. HWAs first appear on trees during spring and early summer. They lay orange-brown eggs, which hatch into minuscule, crawling insects (often compared to sprinkled pepper). 

Once hatched, these insects create the tell-tale woolly growths under tree branches and at the base of needles, which are HWAs’ nests. The insects go dormant during the height of summer’s heat, then reappear in the fall and winter months to feed.

How They Harm Trees

HWAs damage trees by inserting their long mouthparts into branches and withdrawing the tree’s starches, direct results of which are needle loss and branch dieback. Over 4-10 years, infested trees’ canopies begin to wither. The trees may die if left untreated.


Tree care experts have several methods for treating HWA-infested trees, including:

  • Spray: Imidacloprid is an insecticide spray that can be applied to entire trees. As a toxic chemical, however, it may be unsafe to use on trees located near homes.

  • Insecticide Soap and Dormant Oil: Although less toxic than chemical treatments, avoid using soaps and oils near water sources. Moreover, these solutions should be applied during the fall season and should cover the entire tree.

  • Soil Treatment: Administered through a small trench dug around an infested tree, soil treatment can take several months to work. Nevertheless, it is considered the best option.
