Spotted Lanternfly inMontgomery County, OHSPOTTED LANTERNFLY GUIDE
Montgomery County, home to Dayton and its surrounding metro communities, confirmed spotted lanternfly in 2023 as infestations pushed westward across Ohio along the I-70 and I-75 freight corridors. The Dayton metro sits at the crossroads of two of the Midwest's most heavily trafficked interstate routes, making it a high-risk hub for continued SLF spread from Pennsylvania infestations that have been moving across Ohio via the Ohio Turnpike and I-76. Kettering, Beavercreek, and Huber Heights are suburban communities with expanding freight and commuter traffic, while Trotwood's post-industrial landscape — with its extensive disturbed lots and railroad corridors — provides ideal Tree of Heaven habitat supporting SLF establishment. Dayton's rich aviation and manufacturing heritage has also left numerous brownfield sites that readily support Ailanthus colonization.

Tree of Heaven in Montgomery County, OH
The Great Miami River corridor through downtown Dayton and Kettering has Tree of Heaven establishment in riparian floodplain margins where Ailanthus colonizes disturbed shoreline and former industrial sites. Dayton's post-industrial brownfields — concentrated in Trotwood and along the former GM and NCR manufacturing zones — are prime Ailanthus habitat providing extensive SLF host networks. I-75 and I-70 highway medians and interchange areas carry Ailanthus establishment extending the SLF dispersal spine through the county. Norfolk Southern rail corridors through the Dayton metro carry Ailanthus at track margins connecting the county to infested eastern Ohio.
