Spotted Lanternfly inChantilly, VASPOTTED LANTERNFLY GUIDE
Chantilly — a Fairfax County community of 24,000 in the heart of the Dulles tech hub — confirmed SLF in 2021 and is heavily infested. Washington Dulles International Airport's approach zone creates a major concentration of freight and cargo vehicle traffic that accelerates SLF egg mass dispersal throughout the surrounding landscape. The Route 50 and Route 28 intersection is a high-volume commercial and freight corridor where Tree of Heaven colonization along margins supports active SLF populations. Sully Plantation State Historic Site adds historically significant grounds under SLF pressure. The Dulles Corridor tech park landscape concentrates commercial vehicle activity year-round. VA quarantine lifted March 2025.

Tree of Heaven in Chantilly, VA
Washington Dulles International Airport's freight and cargo vehicle concentration makes the approach zone and surrounding Chantilly corridor one of the highest-traffic SLF dispersal nodes in Northern Virginia — heavy commercial vehicles moving through airport access roads and freight facilities carry egg masses throughout the broader Dulles region. The Route 50 and Route 28 intersection has established Tree of Heaven along its commercial margins, providing prime SLF habitat at one of Fairfax County's most active freight corridors. Sully Plantation's historic landscape and the Chantilly tech park office corridors add substantial managed green space under sustained SLF pressure.
