Spotted Lanternfly inChittenden County, VTSPOTTED LANTERNFLY GUIDE

Chittenden County is Vermont's most populous county and home to the Burlington metro area — making it a critical early-warning zone as spotted lanternfly continues its northward march through New England. Designated a watch zone in 2025, Chittenden County sits at the intersection of two major SLF dispersal pathways: the I-89 freight corridor running north from Massachusetts and the Lake Champlain ferry routes connecting Vermont to New York, where SLF is already established. Burlington's active waterfront and rail yard, combined with the commercial activity along Route 2 and Route 2A connecting Burlington, Williston, and Essex, create multiple introduction vectors that require vigilant monitoring. The Lake Champlain shoreline and Winooski River valley provide natural ToH habitat corridors that could accelerate establishment if SLF arrives. Residents throughout the Burlington metro area should inspect vehicles, outdoor equipment, and plants for egg masses — particularly anyone traveling from southern New England.
