The name of the product is "Merit 75WP" and is primarily used on the grape fields of Europe to destroy the apple wooly aphid, which desroys fruit trees and grape vines.

It is 100% effective and is bought in 20 liter buckets, and the dose price is about 4 cents. I believe, but am not sure, it has been approved for use in the US.


Does this pest infest any other species than hemlock?


Yes it does, some evergreen ornamentals and a few deciduous bushes. A company by the name of BAYER, Bern, Switzerland makes a chemical which knocks em dead. Mix a tablespoon to a five gallon bucket of water, dump mixture around the interior of drip edge. Repeat later. $150 buys enough to treat about 6 trees.
