Since December 2021, the Oakland County Invasive Spongy 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. Spongy moth, formerly known as gypsy moth, can be a destructive pest in residential, urban and rural areas as well as forests. Spongy moth caterpillars, in the immature larval stage, feed on the leaves of more than 300 species of trees, including oak, apple, birch and willow. This invasive pest, which is native to Europe, can heavily or even completely defoliate a tree.
The Oakland County Board of Commissioners renewed the Invasive Spongy Moth Suppression Grant Program in September 2022. The grant is administered in partnership with MSU Extension (MSUE) and will again provide funding to Oakland County communities to help them lessen the impacts of this invasive species.
The application deadline for the 2023 program has passed. The 2023 Application Guide provides complete details about the program and is available here.
MSUE maintains an informative website with educational resources about spongy moth and is available online here. The below resources from MSUE may also be helpful to residents and municipalities.
Homeowners who believe they have a spongy moth infestation can contact the MSU Extension office at 248-858-1639 for more information.
