Spotted Lanternfly (SLF) is in the adult stage. As of 09.10.2024 we have not had any reports of egg masses, but are anticipating seeing those soon. Adults are being observed in large numbers especially in the downtown area, east Toledo, and south Toledo, with numbers increasing in other areas of the county. 

 

We continue to encouraging residents to become familiar with this non-native invasive insect - the spotted lanternfly (SLF), and look for the pest in their own landscapes or places they frequent.

The spotted lanternfly has been reported feeding on over 103 species of plants, according to new research (Barringer and Ciafre, 2020) and when including not only plants on which the insect feeds, but also those that it will lay egg masses on, this number rises to 172.
