Spotted Lanternfly inButler County, OHSPOTTED LANTERNFLY GUIDE
Butler County forms the northern suburbs of the Cincinnati metro and sits astride the I-75 corridor — one of the primary freight routes connecting Ohio to the SLF-infested Mid-Atlantic states via Kentucky and beyond. SLF was confirmed in 2023 as populations spread northward from Hamilton County and pushed along the I-75 freight spine that carries heavy commercial traffic between Cincinnati, Dayton, and points north. Hamilton and Middletown are historic industrial cities with rail and highway connections that provide established SLF dispersal pathways, while the rapidly growing communities of Fairfield and West Chester generate significant commuter and commercial traffic. Oxford, home to Miami University, represents a high-movement university community with frequent travel connections to infested areas in Pennsylvania and the Mid-Atlantic.
