It sounds like hemlock woolly adelgid (Adelges tsugae), a small, aphidlike insect that commonly populates hemlock trees. Chemical control options, such as foliar sprays using horticultural oils and insecticidal soaps, are effective when trees can be saturated to ensure that the insecticide comes in contact with the adelgid. As with all pesticides, be sure to follow label instructions.
