The gypsy moth is the most damaging exotic species ever to be introduced to North America. The Gypsy Moth's ability to eat more than one (1) square meter of leaf foliage during its caterpillar stage has defoliated millions of acres of trees and shrubs since being brought to the United States 



Do Not Remove New Gypsy Moth Egg Masses

  • The Fall Survey Crew needs to observe and count the egg mass where it was laid by the female. 
  • Egg masses can be removed in the spring, before they hatch, from February through May
