Gypsy moth treatment at Kosciusko sites tomorrow

DNR aerial treatment to disrupt the mating process of gypsy moths is scheduled for several sites in Kosciusko County tomorrow morning. If weather prevents or stops treatment, it will resume on the next suitable day. 

The treatment sites are in and south of Warsaw. Maps of the areas to be treated and other pertinent information are at

Successful application of the treatment is especially dependent upon the lack of high wind or rain. The treatment will start in the early morning and continue until completed or stopped by weather

The mating-disruption process consists of dropping small plastic flakes from an airplane. One or more treatment airplanes will be assigned to treat the sites. Residents may see other airplanes. An observation plane flies above the treatment planes for safety.

The mating-disruption technique has been used in other states and in Indiana since 1999. It has proven effective where there is very low-level infestation and female moths are hard to find. The gypsy moth, which now has a foothold in some counties in northeast Indiana, was brought to this country from Europe more than 100 years ago, according to Phil Marshall, state entomologist.

"The Indiana Department of Natural Resources has successfully held back introductions of this pest throughout Indiana for more than 20 years. Now that the gypsy moth is within Indiana's borders, however, residents can expect to see more of this pest throughout the next decade," he said.
While the application poses no health threat to people, pets, livestock or other animals, individuals in the treatment areas may notice the small green flakes on their vehicles. Washing vehicles promptly with soap and water will remove the flakes.

Anyone with questions about this project may call toll free at 1-877-INFO DNR (463-6367) between 8:15 a.m. and 4:30 p.m., Monday through Friday.
