The wooly adelgid is expected to kill 80% of the hemlocks in the country and Canada (it does not seem to affect pines as far as I know but I'm not a specialist). The hemlocks that survive adelgid are immune to it - a lucky hemlock or rather a specimen enhanced by human research and doing.
If you turn your hemlock leaves up and see all white underneath, I recommend you treat. The adelgid infestation has decreased significantly during the past recent years.
