Spotted Lanternfly inCambridge, MASPOTTED LANTERNFLY GUIDE
Cambridge — home to MIT and Harvard — sits in Middlesex County on the leading edge of SLF watch zone expansion in the Boston metro. Commuter rail corridors and the MBTA Red Line connecting Cambridge directly to confirmed western Massachusetts populations make early arrival likely. Dense urban tree canopy throughout Harvard Square, Kendall Square, and Inman Square provides ample habitat for rapid SLF establishment once the pest arrives.
