Spotted Lanternfly inAnne Arundel County, MDSPOTTED LANTERNFLY GUIDE
Anne Arundel County — home to Annapolis, Maryland's state capital, and the Naval Academy — confirmed SLF in 2022 as populations spread south through the Baltimore-Washington corridor. The county's Chesapeake Bay shoreline and South County farming areas present unique monitoring challenges. BWI airport perimeter and the Route 2 corridor are primary spread pathways. Quiet Waters Park and the South River waterfront have become notable SLF activity zones, and the county remains under the Maryland statewide quarantine.
Maryland issued a statewide quarantine in March 2026. All movement of regulated articles from Anne Arundel County requires a permit from MD MDA.
