· Cuyahoga County - Total treatment of 32 acres in the BonneBell block.

The process will involve the use of a low flying aircraft just above the tree tops and will occur sometime during the first two weeks of May, coinciding with the insect’s first and second instar caterpillar stages. Treatments are most likely to occur during the early morning hours when weather conditions are ideal. High humidity, low temperature, and low wind are necessary conditions for successful application.
In Cuyahoga, Erie and Lorain counties, the department will use two treatments of BTK, a microbial compound that occurs naturally in numerous species of agricultural and forest insects and is a soil component worldwide. These treatments are not toxic to humans, pets, birds or fish. The two treatments will be applied five to seven days apart.
Pre-recorded daily updates on planned treatment blocks will be available to citizens by calling (614) 387-0907 or (800) 282-1955 ext. 37, after 5 p.m. Maps of application areas can be viewed at www.ohioagriculture.gov by clicking on “gypsy moth updates.”
The gypsy moth is a non-native, invasive species that has been advancing into Ohio from Pennsylvania and Michigan over the last several years. In its caterpillar stage, it 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, 49 of Ohio’s 88 counties have established gypsy moth populations.
The department operates three programs aimed at managing the gypsy moth in Ohio:
“Suppression” program in counties where the pest is established,
“Slow-the-Spread” program in counties within the transition zone, and
“Eradication” program in isolated populations outside the transition zone.
The Suppression program is a voluntary program in which the landowner must request treatment. The focus of the Slow-the-Spread program is to detect and control isolated populations which helps slow the gypsy moths’ natural movement. The Eradication program is designed to eliminate isolated populations that arise ahead of the transition zone, usually caused by human movement.
