The Ohio Department of Agriculture (ODA) will conduct virtual open houses before initiating its spring spraying program to manage the invasive spongy moth in parts of Mount Vernon and surrounding areas. The agency said that the treatments are not harmful to humans, animals, honeybees, or plants.
According to a Mount Vernon news release, spongy moth caterpillars feed on leaves, weakening trees and shrubs and potentially leading to their death. The ODA identified a growing population in the area that necessitates control measures. The treatment area includes the eastern portion of Mount Vernon, the Village of Gambier, and much of Monroe and Pleasant Townships, extending east to Monroe Mills Road.
The news release indicated that prior to the aerial treatments in spring, two virtual open houses will be held to inform the public about the procedures. These sessions are scheduled for noon on Tuesday, February 12, and at 6 p.m. on Wednesday, February 12. Links for participation will soon be available on the ODA website at agri.ohio.gov. Residents who cannot attend can submit public comments via email at plantpest@agri.ohio.gov until February 29.
The ODA plans to use airplanes or helicopters flying between 100 to 200 feet above treetops to spray SPLAT GM-O insecticide—a non-toxic, biodegradable formulation employing pheromones to disrupt spongy moth mating patterns. If found on vehicles or other surfaces, it can be removed with soap and water.
The spongy moth (Lymantria dispar) has been an invasive species in the United States for centuries. It was previously known as the gypsy moth until 2022 when its name was changed by the Entomological Society of America due to concerns over derogatory connotations associated with "gypsy."
According to historical accounts cited in the news release, Etienne Trouvelot introduced the insect into Massachusetts in the mid-1860s with hopes of using it for silk production; however, some larvae escaped into nearby woods.
