Spotted Lanternfly inHarrisonburg, VASPOTTED LANTERNFLY GUIDE
Rockingham County confirmed SLF in 2023, with Harrisonburg as the Shenandoah Valley's largest independent city and a major SLF spread node. James Madison University's campus features one of the most extensive institutional tree canopies in the valley, providing substantial SLF habitat within the city's core. I-81 runs directly through Harrisonburg and carries some of the highest freight volumes on its entire Virginia route — the surrounding poultry processing industry generates constant heavy vehicle traffic connecting farms throughout Rockingham County. The Shenandoah Valley's poultry industry — one of the largest in the nation — faces distinct SLF-related stress monitoring as populations establish. Eastern Mennonite University and the emerging downtown arts district add additional community dimensions to SLF management awareness. VA quarantine lifted March 2025.

Tree of Heaven in Harrisonburg, VA
James Madison University's large campus tree canopy — spread across a substantial urban footprint — provides prime SLF habitat sustaining populations through the heart of Harrisonburg. I-81 freight corridor through the city carries industrial-scale poultry and agricultural vehicle traffic that moves egg masses throughout Rockingham County's vast farm network. Tree of Heaven is established along I-81 margins, stream corridors through the Harrisonburg urban area, and farm road margins throughout the surrounding Shenandoah Valley agricultural landscape. Eastern Mennonite University campus and the downtown arts district street trees add further managed habitat under active SLF colonization. The Rockingham County agricultural sector — spanning poultry, grain, and cattle operations — is under close monitoring as SLF populations build in this critical farming region.
