Spotted Lanternfly inAllen County, INSPOTTED LANTERNFLY GUIDE
Allen County — anchored by Fort Wayne, Indiana's second-largest city — confirmed spotted lanternfly in 2023 as the pest expanded its range westward from Ohio along the I-469 and US-30 freight corridors. The Maumee River watershed connecting Fort Wayne to established Ohio infestations provides a natural dispersal pathway, and the county's active freight and manufacturing economy accelerates the risk of egg-mass transport on vehicles and equipment. New Haven and the eastern communities closest to the Ohio border are the highest-priority monitoring zones.

Tree of Heaven in Allen County, IN
Tree of Heaven is found along Allen County's railroad corridors, the Maumee and St. Marys river margins, and disturbed urban edges throughout Fort Wayne. The Norfolk Southern rail corridor running east-west through the county toward Ohio, and the CSX lines serving Fort Wayne's industrial areas, represent the primary introduction and spread pathways requiring regular ToH inventory and SLF surveillance.
