The Ohio Department of Agriculture will perform aerial treatments in Fulton County designed to control the gypsy moth population. The treatments are currently scheduled for Thursday in the Lyons, Swanton, and Wauseon areas.

Treatments are administered using a low-flying aircraft that flies just above tree tops. High humidity, low temperature, and minimal wind are crucial for a successful application. Treatment will most likely take place during early morning hours.

Locally, the ODA will use Foray (Btk), a naturally occurring bacterium found in the soil that interferes with the caterpillars’ feeding cycles. These treatments are not harmful to humans, pets, birds or fish.

Treatments on a total of 2,517 acres will also be administered in Fulton, Auglaize, Cuyahoga, Hancock, Lorain, Lucas, Paulding, Seneca, and Williams counties. They will begin in mid-May, as larva and leaf development reaches the optimal threshold for treatment.

Ohioans can view maps of treatment blocks at www.agri.ohio.gov. When the project begins, daily updates on treatment progress across the state will be available on the website or by calling 614-387-0907 or 614-728-6400.

Gypsy moths are invasive insects that defoliate over 300 species of trees and shrubs. In its caterpillar stage, the moth feeds on the leaves of 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. In Ohio, 51 counties are currently under gypsy moth quarantine regulations.

The department uses three programs to manage the gypsy moth population in Ohio. The suppression program is used in counties where the pest is already established, but landowners voluntarily request treatment to help suppress populations. The second program, slow-the-spread, occurs in counties in front of the larger, advancing gypsy moth population. The third program is the eradication program, used in counties where isolated populations develop ahead of advancing moth populations due to human movement of the moth. Officials work to detect and control isolated populations to slow the overall advancement of the gypsy moth infestation.
