The Ohio Department of Agriculture will begin aerial treatments designed to disrupt the gypsy moth mating process on 45,675 acres in Delaware and Franklin counties. Airplanes will fly 100 to 200 feet above the tree tops to apply the treatment. Weather permitting, treatments will begin in central Ohio the week of June 23 and occur over one or two days.
To help protect Ohio’s diverse habitat, the Ohio Department of Agriculture operates multiple programs aimed at managing the gypsy moth in Ohio. One such program, the Slow the Spread program, focused on monitoring, detecting and reducing isolated populations to slow the gypsy moth's movement across the state through aerial treatments.
In all counties receiving treatment, the department uses a single application of the product, Disrupt II. This product does not kill the moth, but it disrupts the mating process by confusing the male as it searches for a female mate. Disrupt II is not harmful to birds, plants, pets or humans. Pre-recorded updates about planned treatment blocks are available to citizens by calling (614) 387-0907 or (800) 282-1955 ext. 37 after 5 p.m.
The gypsy moth is a non-native, invasive species that feeds on the leaves of more than 300 different trees and shrubs, and is especially fond of Oak. A healthy tree can usually withstand only two years of defoliation before it is permanently damaged or dies. To date, 51 of Ohio's 88 counties have established gypsy moth populations.
