Spotted Lanternfly inEssex County, NJSPOTTED LANTERNFLY GUIDE
Essex County, with Newark as its county seat, is one of New Jersey's most heavily infested urban counties — confirmed in 2019, SLF populations have become deeply established throughout the county's urban forest and suburban parks. Newark's dense NJ Transit rail network and commuter corridors have accelerated spread, and Branch Brook Park — famous for its cherry blossoms — has become a significant SLF zone. The Ironbound neighborhood and Orange/East Orange urban canopy show consistently high SLF activity through the fall season.
