Spotted Lanternfly inGuilford County, NCSPOTTED LANTERNFLY GUIDE
Guilford County — encompassing Greensboro and High Point, the heart of the Piedmont Triad — entered the SLF watch zone in 2023. The convergence of I-40, I-85, and I-73 at the Piedmont Triad makes Guilford County one of the most strategically important freight nodes in North Carolina. The I-73 corridor runs directly north toward Virginia's established SLF infestation zones, creating a direct potential pathway for SLF advance into the Triad. Piedmont Triad International (PTI) Airport handles significant freight volumes connecting the region to the Mid-Atlantic. UNCG and NC A&T campuses, along with the Greensboro Arboretum, are priority institutional and ecological monitoring sites as this major North Carolina metro area watches for the leading edge of SLF invasion.

Tree of Heaven in Guilford County, NC
Tree of Heaven is present along the I-40, I-85, and I-73 road margins throughout Guilford County, creating potential SLF dispersal pathways from the Virginia infestation frontier southward into the Piedmont Triad. PTI Airport freight perimeter and the I-73 corridor approach roads from the Virginia border are priority early-detection monitoring zones. The Greensboro Arboretum and UNCG/NC A&T campus edges have Ailanthus colonization in disturbed margins that could support SLF establishment. High Point's furniture industry generates substantial freight movement throughout the Southeast — an additional vector for monitoring as SLF approaches this major North Carolina watch zone.
