Spotted Lanternfly inManassas, VASPOTTED LANTERNFLY GUIDE
Manassas — the Prince William County seat — confirmed SLF in 2022. The I-66 transport corridor is a primary SLF spread vector connecting the DC metro infestation zone to Northern Virginia's exurban communities, with Manassas at the leading edge. VRE Manassas line commuter service moves thousands of workers daily between Manassas and the heavily infested DC metro, accelerating dispersal. Manassas National Battlefield Park's historically significant tree canopy is under documented SLF pressure. Bull Run stream valley provides natural ToH habitat running through the city. VA quarantine lifted March 2025, confirming statewide establishment.

Tree of Heaven in Manassas, VA
Manassas National Battlefield Park — site of two pivotal Civil War battles — now faces an invasive species threat as Tree of Heaven and SLF spread through the battlefield's historic tree stands. Bull Run stream valley has established ToH populations providing prime SLF habitat running through Manassas and into surrounding Prince William County. The I-66 corridor has heavy ToH colonization along highway margins, serving as the primary SLF spread vector west from the DC metro. VRE Manassas line stations concentrate commuter vehicles daily, accelerating egg mass transport throughout the exurban spread front.
