Gypsy Moth Suppression

Release Date: June 11, 2024

If you think you are having an infestation of gypsy moth, please visit the NJ Department of Agriculture’s Gypsy Moth Suppression website at for more information. Information is available including an Gypsy Moth Suppression Q and A section as well as information specifically for homeowners. The Suppression Program is not operated on a local level but through the State Department of Agriculture, conducting aerial defoliation and ground egg mass surveys. As reported on the State webpage below:

Q: What can a homeowner do to be included in the Department’s Cooperative Gypsy Moth Suppression Program?

A: Since there are certain legal and fiscal requirements for participation in the aerial spray program, the Department can only work with local municipal governments. However, when a municipality requests an egg mass survey, we send Department inspectors to the municipal building to pick up a map and request locations of complaints of gypsy moth damage. The homeowner can play an active role in this process by requesting that your municipal officials ask the Department for a gypsy moth egg mass survey and filing a written complaint about the location of these gypsy moth infestations with your municipality by early September. Follow up this letter with another request in late December to determine if your area was indeed included in a spray block and if your municipality is participating in the cooperative program.
