Although the Spotted Lanternfly does not pose a direct threat to human health, it feeds on a variety of plants, including grapes, hops, stone fruits, and hardwood trees. Its feeding weakens these plants and produces a sticky, sugary fluid that encourages the growth of sooty mold, further harming crops. While the SLF prefers the Tree of Heaven (Ailanthus altissima), it can significantly impact many other species.
Spotted Lanternfly (SLF) is an insect pest that has had people on high alert for some time now. While Darke County is not currently in quarantine, it is important to keep an eye out for SLF and report it if you think you see it.
