Pigeons often like to stay in areas that provide plenty of shade, water and food. A pond in your backyard can be an unwanted habitat for pigeons, and it's important to remove pigeons from the area as soon as possible. Too many pigeons in your backyard can increase the number of predators around the area and produce an excess of droppings that can spread disease. You must also make sure that pigeons don't try to nest on your roof or get into areas of your home.
Use a hose or automatic sprinkler system to spray the pigeons every time they arrive near your pond. This can be effective if you have a few pigeons occasionally entering your backyard.
Purchase a plastic owl from your local home and garden retailer, and then place it near your backyard pond to deter the pigeons. Some more expensive models come equipped with a motion sensor that uses an ultrasonic sound to keep the pigeons away.
Use an ultrasonic device that contains a motion sensor that will detect when the pigeons are near your pond. This is a more expensive option, but it will typically keep the pigeons away.
Place bird spikes near the area around your pond or on any nearby tree branches where the pigeons have been roosting. Bird spikes are strips of small spikes that can be placed in areas where the pigeons often land.
Contact pest control or wildlife control in your area if your pigeon problem continues. It may be necessary to hire a professional to remove any pigeon nests near your home.
