The Ohio Department of Agriculture (ODA) has announced the 2017 Gypsy Moth Treatment Project Open Houses that will be held this winter prior to treatment applications that will be made later in the spring and summer. 



The gypsy moth is currently in the egg mass stage where it has been since late last summer.  This spring, caterpillars will hatch and the feeding frenzy will begin.

Treatment applications are directed at the caterpillar stage and are made as a way to manage this invasive species by slowing its spread as part of a larger multi-state regional program in cooperation with the USDA Forest Service.  A goal is to reduce gypsy moth populations and the potential damage to host trees as shown below.

Aerial treatments are scheduled to be applied in the following Ohio counties in 2017:  Allen; Athens; Fairfield; Franklin; Hancock; Hardin; Jackson; Licking; Lucas; Marion; Morgan; Muskingum; Paulding; Perry; Ross; Union; Washington; and Wyandot.
