Gypsy Moth Program


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

The Michigan State Law prohibits a Gypsy Moth Survey Team from entering your property to look for egg masses if any of these types of signs are displayed at the entrance:
  • Properties marked - “No Trespassing” or “Private and Gated/cabled” or “Private - No Trespassing”
  • Private driveways marked - “Private - Do Not Enter” or “No Trespassing” or “Private Driveway-Gated or Cabled”
To grant permission and be surveyed --- put wording below your sign that says: “Except Gypsy Moth” or contact the program office for a sticker.
