Spotted Lanternfly inTippecanoe County, INSPOTTED LANTERNFLY GUIDE
Tippecanoe County — home to Purdue University and the Lafayette metro — entered watch zone status in 2024 as spotted lanternfly advanced along I-65 from the Indianapolis-area detections to the south. Purdue's agricultural research campus and the university community's broad awareness make this county an important early-detection hub, while the Wabash River corridor and active freight traffic on I-65 and US-52 create realistic spread pathways. ISDA is coordinating with Purdue Extension to monitor and educate residents across the county.
