Spotted Lanternfly inProvidence County, RISPOTTED LANTERNFLY GUIDE
Providence County is the most populous county in Rhode Island and the epicenter of SLF activity in the state, confirmed in 2023. The dense urban corridor stretching from Providence through Pawtucket and Central Falls into Woonsocket follows the Blackstone River rail and highway network, providing direct spread pathways from Connecticut and Massachusetts. Dense urban tree canopy and Ailanthus stands along the Woonasquatucket River have accelerated local establishment.
