Spotted Lanternfly inCrawford County, PASPOTTED LANTERNFLY GUIDE
Crawford County in western Pennsylvania confirmed spotted lanternfly in 2024, representing the SLF front advancing through the Oil Region and Allegheny Plateau. Meadville, the county seat, sits at the crossroads of I-79 and US-322 — corridors that link the Pittsburgh metro to Lake Erie and have served as the primary SLF dispersal pathways through this largely rural county. Conneaut Lake and the surrounding recreation areas present a spread risk through seasonal visitor traffic, while Titusville's historic oil industry legacy has created brownfield and disturbed-land habitats ideal for Tree of Heaven colonization and SLF establishment.
Pennsylvania is under a statewide spotted lanternfly quarantine. Moving plants, outdoor items, or vehicles out of quarantined areas requires inspection.
