Spotted Lanternfly inLambertville, NJSPOTTED LANTERNFLY GUIDE
Lambertville — Hunterdon County's Delaware River art gallery and canal town — confirmed SLF in 2019. Sitting directly across the Delaware River from New Hope, PA, these twin canal towns share a dense Tree of Heaven corridor along both the D&R Canal towpath and the Delaware River waterfront. Lambertville's art gallery district with outdoor dining, the Prallsville Mills historic site, and the Route 29 river corridor all see concentrated visitor traffic that accelerates vehicle-based SLF spread. Delaware Bay wine corridor connections place area vineyards at ongoing risk.

Tree of Heaven in Lambertville, NJ
The D&R Canal towpath running through Lambertville is one of the most TOH-dense corridors in Hunterdon County — a primary SLF habitat and spread pathway connecting populations along the entire length of the canal from Lambertville north to Trenton. The Delaware River waterfront opposite New Hope, PA, creates a continuous cross-river SLF exchange. Bull's Island Recreation Area and Prallsville Mills State Historic Site provide additional prime TOH habitat. Route 29's Delaware River corridor is a documented high-activity SLF zone extending the infestation through central Hunterdon County.
