gypsy moth larva
The gypsy moth is native to Europe and Asia but has become a major pest of hardwood forests in the eastern United States.
Natural spread first brought gypsy moths to northern Virginia around 1980 and populations now cover approximately two thirds of the state.

Gypsy moth is an outbreak pest. Population levels can remain low for several years before causing major problems. The last major outbreak was in 2001, when over 440,000 acres were defoliated in Virginia.
There are several things homeowers can do to protect their trees and minimize the chance of spreading moths to new areas.
