All aerial treatments conducted by the Indiana Department of Natural Resources (DNR) Divisions of Forestry and Entomology & Plant Pathology to slow the spread of spongy moth were completed yesterday. 
Spongy moth is one of North America's most devastating invasive forest pests and has caused thousands of acres of defoliation across the eastern United States. 

Treatments for this destructive pest were conducted in Adams, Allen, Huntington, Starke, Wabash, Wayne and Whitley counties.

The treatments done most recently used a mating-disruption process that consists of using a product called SPLAT GM-Organic, an organic product made with food-grade materials. The droplets have pheromone that disrupts the insect's mating cycle. 

SPLAT GM-Organic is a biodegradable, food grade material infused with the female moths’ pheromone to attract and confuse the male moths so that mating does not take place. This material does not affect people, animals, plants, or any insects other than spongy moth. 

The DNR will return continue aerial treatments next spring and summer to continue the battle to slow the spread of this insect. 

During the treatment period, updates are posted on X (formerly Twitter) @INdnrinvasive. DNR also issues status updates via news release.
