What damage can pigeon droppings cause to my property and garden? While it is not unknown to many that pigeon droppings can be unsanitary and unhealthy for people, it is less commonly known that pigeon droppings can also pose many risks to plants, other animals and sometimes even sometimes serious safety hazards. We addressed our concerns to local pigeon removal experts and there is what they answered “If a person owns a garden, it is very important that the person calls their local animal control right away when he or she begins to notice signs of pigeons living on or near the person’s home or close to the person’s garden.” They also pointed out why pigeon droppings can be dangerous.
