Spotted Lanternfly inStamford, CTSPOTTED LANTERNFLY GUIDE
Stamford — Fairfield County's financial hub and Connecticut's second-largest city — confirmed SLF in 2023. Sitting directly on the I-95 New England corridor and the Merritt Parkway, Stamford is a primary gateway for SLF moving from Westchester County, NY into southwestern Connecticut. Metro-North New Haven Line carries thousands of daily commuters between confirmed NY infestation zones and Stamford. The downtown dense commercial core and Greenwich-adjacent neighborhoods are under active monitoring. Stamford Harbor's industrial waterfront provides prime Tree of Heaven habitat along the Long Island Sound shoreline.

Tree of Heaven in Stamford, CT
Stamford Harbor's industrial waterfront has established Tree of Heaven populations along the Long Island Sound shore — a primary SLF habitat corridor running into the city from the west. The I-95 and Merritt Parkway corridors carry heavy freight and commuter traffic from heavily infested Westchester County, NY directly into Stamford, making these highways the main SLF introduction vectors into Fairfield County. Metro-North New Haven Line rail margins and the Mianus River Gorge corridor provide additional TOH-supported habitat through Stamford's western neighborhoods.
