Resident Canada geese are responsible for significant landscape damage, and can cause a major financial impact to property owners. The droppings are unsightly, and there is evidence that the bacteria can be harmful to water supplies, and unhealthy for humans. The Geese can become aggressive during the nesting and hatching season, and may expose property owners to civil litigation. The overpopulation of Geese has caused many jurisdictions to allow large scale “roundups” and euthanasia.
