The purpose of the Gypsy Moth Suppression Program is to protect Bay County's highly valued trees from the damaging effects of the gypsy moth caterpillar. Gypsy moth populations can build to intolerable levels in a short time. When this build up occurs, the caterpillars will defoliate large trees in a few weeks, invade yards and recreational areas, and become a general nuisance to people living in infested areas.

Services offered by the Gypsy Moth Suppression Program include:
- Monitoring all wooded and residential areas of Bay County for the presence of gypsy moth life stages.
- Conduct suppression/control activities in heavily infested areas of the county. This includes determining where out-break level populations occur, contracting with an aerial applicator and conducting treatment projects in highly infested areas, and evaluation of treatment results.
- Cooperate with the Michigan Department of Agriculture's (MDA) grant program for gypsy moth suppression to ensure maximum reimbursement on treatment and administrative costs. By following MDA guidelines and participating in the grant program, Bay County is able to reduce the cost of the program for Bay County taxpayers.
- Conduct educational programs for schools, property owners, and local civic groups. The program utilizes Bay County Pinconning Park as a staging area for many of these presentations, which include information on the life cycle of the gypsy moth, how it fits into our local ecology, and methods for controlling the gypsy moth.
