Spotted Lanternfly inGreenbelt, MDSPOTTED LANTERNFLY GUIDE
Greenbelt — Prince George's County's historic New Deal planned community and home to NASA Goddard Space Flight Center — confirmed SLF in 2022 and is now heavily infested. The I-495/I-95 Beltway interchange is a major freight and commuter dispersal node, and Greenbelt Park (NPS) provides extensive natural TOH habitat directly adjacent to the city's planned residential areas. The Metro Green Line connects Greenbelt directly to DC's established infestation zone, and the historic New Deal woodland corridors sustain established SLF colonies throughout this nationally significant planned community. MD statewide quarantine in effect as of March 2026.
