Spotted Lanternfly inDover, DESPOTTED LANTERNFLY GUIDE
Kent County confirmed SLF in 2018, placing Dover — Delaware's state capital — among the earlier East Coast confirmations. Dover Air Force Base, one of the busiest air freight hubs on the East Coast, raises significant federal biosecurity concerns around SLF spread via military and cargo aircraft ground vehicles. The US-13 commercial corridor is a primary vehicle-based spread vector through the city, and the Delaware Agricultural Museum's proximity adds concern for the state's farming communities. NASCAR Dover Motor Speedway brings massive seasonal vehicle traffic concentrations that can introduce and disperse SLF egg masses across a wide radius.

Tree of Heaven in Dover, DE
Dover's US-13 commercial corridor has highway margin Tree of Heaven populations serving as a primary SLF spread vector through the city and into Kent County's agricultural districts. Dover Air Force Base perimeter and surrounding areas have disturbed-edge TOH habitat raising biosecurity concerns given the base's role as one of the East Coast's most critical air freight hubs. Delaware Agricultural Museum Farm Park adjacent areas and Silver Lake corridor add natural riparian TOH habitat through the urban core. NASCAR Dover Motor Speedway's massive seasonal vehicle influx concentrates regional vehicle traffic — a well-documented SLF egg mass dispersal event occurring multiple times annually.
