Spotted Lanternfly inTioga County, PASPOTTED LANTERNFLY GUIDE
Tioga County, in Pennsylvania's northern tier near the New York border, confirmed spotted lanternfly in 2024 as the infestation frontier continues expanding into the Endless Mountains and Pine Creek Gorge region. The county's timber industry, state forest lands, and agricultural operations along the Tioga and Cowanesque river valleys face new SLF risks. Wellsboro, the county seat, and Mansfield University are key community awareness and monitoring hubs as this scenic outdoor-recreation destination responds to the growing threat.
Pennsylvania is under a statewide spotted lanternfly quarantine. Moving plants, outdoor items, or vehicles out of quarantined counties requires inspection.
