WARREN COUNTY, NY (WRGB)--The Department of Environmental Conservation says a minor infestation of Hemlock Woolly Adelgid was confirmed on the lands of the Forest Preserve in Lake George, back on July 18th.

The DEC says it is the first known infestation of Hemlock Woolly Adelgid in the Adirondacks.

The most effective treatment method for control of HWA is the use of insecticides.

The insecticide is applied to the bark near the base of the hemlock tree and are absorbed and spread through the tissue of the tree. When HWA attaches itself to tree to feed, it receives a dose of the pesticide and is killed.

“To track and prevent the spread of this invasive pest, Hemlock Woolly Adelgid, DEC has surveyed 250 acres of forest in the Adirondacks,” said DEC Commissioner Seggos. “Preventing the spread of invasive species is the most effective way to fight and address the damage these species can cause to our natural resources. DEC encourages hikers, campers, boaters, sportsmen, and others recreating on or along forestlands in northern Schenectady, Saratoga, and southern Warren counties to check Eastern Hemlock trees and report any HWA infestations.”

More information on HWA, including identification, control techniques, and reporting possible infestations can be found at Cornell’s New York State Hemlock Initiative or the DEC website here.

You can also call DEC's toll-free Forest Pest Information Line at 1-866-640-0652 to ask questions and report possible infestations.
