Hemlock Wooly Adelgid

Invasive Species

Emerald Emerald Ash Borer and Hemlock Woolly Adelgid are here!

Emerald ash borer and Hemlock Woolly Adelgid are infesting and killing trees in Broome County. As the populations of these invasive insects grow, more and more trees will become infested and die.  

Emerald Ash Borer (EAB)

EAB is an invasive wood boring beetle from to Asia that infests and kills all native species of ash trees in the United States.  EAB was first detected in Broome County in 2014, and it has now spread across the southern portion of Broome County.  Dead, infested ash trees have been found in the towns of Conklin, Kirkwood, Vestal, and Union, and in the City of Binghamton.  EAB will eventually kill all unprotected ash trees in the County.  The links below provide information on identifying ash trees and EAB infestations, as well as options for protecting trees with insecticides.

Hemlock Woolly Adelgid (HWA)

HWA is a tiny, aphid-like insect that damages and kills our native eastern hemlock trees by sucking out moisture and nutrients while it feeds.  HWA was detected in Broome County in 2010.  It has been found in numerous locations in Broome County from the Pennsylvania State line to the Town of Triangle.  Protective insecticides are available for treating hemlock trees, and researchers are working on promising biological controls.  The links below provide detailed information on  HWA, including options for treating trees with insecticides.
