A good management program tends to be a maintenance type activity rather than a quick fix. The first step of a goose management program is to identify all of the goose attractions in the immediate area and to eliminate or limit those attractions. Water is an attraction in itself. Limiting goose access to the pond through the installation of overhead grid wires has proven effective in many areas. If your pond has an aerator, turn it off in the winter and allow your pond to freeze.
Open water is extremely attractive in the winter when many ponds are frozen over.

If you have been feeding the geese, this must stop if you want the geese to leave.
