Moth Suppression Program


The 2022 Oakland County Moth Suppression Grant Program has provided matching grants to cities, villages, and townships to support their efforts in mitigating the impacts of Lymantria dispar, an invasive moth species also known as spongy moth. In September 2021, the Oakland County Board of Commissioners approved a one-time appropriation of $250,000 for the program, which is administered by Michigan State University Extension. Grant applications have been open to municipalities that participated in the required training, and mitigation efforts have kicked off for the 2022 season. Maps related to the program can be found below:
