Can hemlocks recover from woolly adelgid?
First, we have confirmed a high level of long-lasting control of hemlock woolly adelgid afforded by a single administration of the systemic insecticide imidacloprid. Second, we have demonstrated that after adelgid populations are suppressed, hemlocks will recover by producing new growth on most branches.
