We have been busy squashing! More effective than killing the bugs themselves is removing their favorite host tree- the also invasive Ailanthus altissima aka Tree-of-Heaven. Removal of these trees once they are more than 1/2" in diameter does require herbicide application. Learn how to identify and remove them at https://ohioline.osu.edu/factsheet/f-65
As spotted lanternflies reach their most noticeable stage of the year, residents are encouraged to eliminate these invasive insects whenever they are seen. Spotted lanternflies damage a variety of trees and grapevines, produce a sticky substance known as honeydew that can lead to mold growth, and disrupt native ecosystems by competing with local species. The pest continues to spread throughout Ohio, with Franklin County remaining one of the state's most heavily infested areas.
We encourage residents to stay informed and follow best practices to help slow the spread. City of Grandview Heights is following guidelines provided by ODA.
