Spotted Lanternfly inKane County, ILSPOTTED LANTERNFLY GUIDE
Kane County stretches along the Fox River Valley in the western Chicago metro and entered watch zone status in 2024. The county is bisected by the Fox River, which runs through Aurora, Batavia, Geneva, and St. Charles before continuing north to Elgin — providing a continuous riparian corridor with abundant Tree of Heaven that could channel SLF dispersal from south to north. Aurora, the county seat and Illinois's second-largest city, is a major freight and highway node at the junction of I-88 and I-90, where vehicle traffic from Indiana and the broader Midwest regularly passes through. Union Pacific and BNSF freight lines traverse the county, linking it directly to Chicago's rail network and to Indiana's active SLF infestation zone.

Tree of Heaven in Kane County, IL
Tree of Heaven colonizes the Fox River margins throughout Kane County, from Aurora in the south through Batavia, Geneva, and St. Charles to Elgin in the north, providing a near-continuous Ailanthus corridor running the length of the county. Railroad rights-of-way for Union Pacific and BNSF lines through Aurora and Elgin carry established ToH populations that make rail-assisted SLF introduction a key risk pathway. I-88 and Route 31 highway margins in Aurora and the Fox River bluffs north of Geneva are priority locations for early detection monitoring.
