The Ohio Department of Agriculture (ODA) has recently escalated its response to certain threats, making it more important than ever for residents to know what’s crawling, hopping, and biting in their neck of the woods.
1. The Spotted Lanternfly: A Statewide Emergency
As of early 2026, the ODA has officially issued a statewide quarantine for the Spotted Lanternfly (SLF). While these insects might look striking with their red underwings and black-speckled bodies, they are an absolute menace to Ohio’s multi-billion dollar wine and grape industry.

- The Threat: They drain sap from plants, particularly grapevines, black walnuts, and hops, leaving behind a sticky “honeydew” that promotes black sooty mold.
- What to Look For: In April, you won’t see the colorful adults yet. Instead, look for egg masses—grey, mud-like smears on tree trunks, vehicles, and outdoor furniture.
