Spotted Lanternfly inHackensack, NJSPOTTED LANTERNFLY GUIDE
Bergen County confirmed SLF in 2019, placing Hackensack — the Bergen County seat — among the earliest NJ establishments. The I-80 and Route 4 interchange is a primary freight and commuter corridor connecting Hackensack to the George Washington Bridge and New York City, making it a critical SLF dispersal node in northeastern New Jersey. The Hackensack River waterfront has established Tree of Heaven populations providing prime SLF habitat through the city's urban core. The Bergen County Courthouse green's significant urban tree canopy and the Hackensack Meridian Health campus's extensive grounds are prominent SLF hotspots. NJ Transit's Pascack Valley Line concentrates commuter traffic that accelerates SLF egg mass dispersal through Bergen County.

Tree of Heaven in Hackensack, NJ
The Hackensack River waterfront has established Tree of Heaven populations running through Hackensack's urban core — a primary SLF habitat corridor connecting city populations to the broader Bergen County infestation zone. The I-80 and Route 4 interchange area is heavily colonized by ToH along highway margins, serving as a major SLF dispersal vector moving egg masses between the George Washington Bridge corridor and the New Jersey interior. Bergen County Courthouse green's urban tree canopy and the Hackensack Meridian Health campus greenspaces are established SLF hotspots requiring active monitoring. NJ Transit Pascack Valley Line rail corridors are documented SLF spread vectors through northeastern New Jersey.
