Geese are federally protected and may only be trapped by properly-permitted individuals.
Habitat modification typically is the best way to control Canada geese and keep areas safe. Banning people from feeding the birds helps reduce populations, as fed geese tend to become permanent residents. Canada geese stay away from tall grasses that may hide predators, so creating barriers of natural vegetation and building fences around bodies of water can be effective. Certain harassment methods work, as well, including trained dogs, lasers, and motion sensors.
