Unfortunately, an insect is killing our hemlock trees. The only option is an insecticide. Treating trees for hemlock trees for woolly adelgid is fairly straightforward.

You simply apply an insecticide to the soil near the tree and the tree takes up the product. The sap of the tree then becomes poisonous to the adelgid which drinks hemlock sap as its food.

You can use liquids that you mix up in a bucket and pour on the soil:

Merit

Safari

Or you can use pellets that you bury near the tree:

CoreTec

Treatments last 5 years.

Trees that are not more than 50% defoliated have a good chance to recover.

READ THE LABELS ON PESTICIDES CAREFULLY AND FOLLOW DIRECTIONS!!! Pesticide users are responsible for the proper use of the products they purchase.
