Spotted Lanternfly inWoonsocket, RISPOTTED LANTERNFLY GUIDE
Woonsocket confirmed SLF in 2024, bringing Rhode Island's Blackstone River Valley mill city into the active monitoring zone. The Blackstone River — the birthplace of the American Industrial Revolution — runs through the urban core with established Tree of Heaven along its banks, providing prime SLF dispersal habitat connecting Woonsocket to Pawtucket and Providence populations downstream. Dense urban brownfield lots throughout the legacy mill district accelerate SLF establishment conditions.

Tree of Heaven in Woonsocket, RI
The Blackstone River corridor through Woonsocket is densely colonized by Tree of Heaven along its historic mill-town riverbanks — the same disturbed industrial margins that characterized early SLF establishment in Pawtucket. Railroad corridors and urban brownfield lots in the downtown mill district provide additional prime TOH habitat where SLF spreads readily along river banks and rail rights-of-way.
