The Ohio Department of Agriculture (ODA) announced on March 10, 2025, that the box tree moth (BTM) (Cydalima perspectalis, family Crambidae) quarantine zone has been expanded in southwest Ohio. As of yesterday, the BTM quarantine now includes the following counties: Butler, Clermont, Greene, Hamilton, Miami, Montgomery, and Warren.

Newly affected nursery stock producers can contact their ODA Nursery Inspector to implement a Compliance Agreement. The Agreement includes a BTM pest management plan developed by the ODA/USDA in conjunction with research scientists.

Compliance Agreements are aimed at reducing the business impacts of a quarantine while at the same time protecting those outside the regulated areas from BTM. As noted in the ODA announcement, Green Industry professionals can contact the Plant Pest Control Section at 614-728-6400 if they have any questions about the new regulation.
