Continuing the battle against hemlock woolly adelgid

On Oct. 27, 2022 the New York State Hemlock Initiative released predator beetles called laricobius nigrinus, which eat the invasive hemlock woolly adelgid, at Paradise Bay on Lake George.

It is one of three biocontrols the state is using to establish a predator-prey relationship in hopes of saving the Lake George area’s hemlock trees. In the meantime, the state Department of Environmental Conservation is using insecticide to treat some of the infected hemlock trees to buy time for these predator bugs to establish.

    Thank you for this very informative video. Given the massive spread of invasives, using invasives to kill invasives, while frightening, is currently the only real alternative in many instances.
