Hemlock Woolly Adelgid
What can the layman do about that? The most loathsome species are indigenous: biting/stinging insects and poison ivy.
You can use any organic horticultural oil or soap to control woolly adelgid. Loathsome as some stinging insects migjt be they are actually quite beneficial environmentally. Most hornets and wasps eat many other pest insects. The chemical agents used to control stinging insects are far worse that the insects themselves. If you think poison ivy is bad check out giant hogweed, an invasive that is for the moment rare in the gunks.
