Pigeon Removal and Control Methods
Pigeons or Rock Doves cause significant damage to building from their feces. These droppings also cause several diseases that humans can contract. They can be a pest at farms causing diseases to be transmitted to cattle. There are many methods of controlling pigeons. when using visual or auditory methods I recommend using both in conjunction for better results.
Pigeon droppings deface and accelerate the deterioration of buildings and increase the cost of maintenance. Large amounts of droppings may kill vegetation and produce an objectionable odor. Pigeon manure deposited on park benches, statues, cars, and unwary pedestrians is aesthetically displeasing. Around grain handling facilities, pigeons consume and contaminate large quantities of food destined for human or livestock consumption.
Pigeons may carry and spread diseases to people and livestock through their droppings. They are known to carry or transmit pigeon ornithosis, encephalitis, Newcastle disease, cryptococcosis, toxoplasmosis, salmonella food poisoning, and several other diseases. Additionally, under the right conditions pigeon manure may harbor airborne spores of the causal agent of histoplasmosis, a systemic fungus disease that can infect humans.
The ectoparasites of pigeons include various species of fleas, lice, mites, ticks, and other biting insects, some of which readily bit people. Some insects that inhabit the nests of pigeons are also fabric pests and/or pantry pests. The northern fowl mite found on pigeons is an important poultry pest.
Pigeons located around airports can also be a threat to human safety because of potential bird-aircraft collisions, and are considered a medium hazard to jet aircraft by the US Air Force. There are many different products that are effective for removing pigeons from sonic devices, to tactile repellents. To enter products for removal click on Pigeon and bird removal products.
Pigeon General Biology, Reproduction, and Behavior
The common pigeon was introduced into the United States as a domesticated bird, but many escaped and formed feral populations. The pigeon is now the most common bird pest associated with people.
Pigeons inhabit lofts, steeples, attics, caves, and ornate architectural features of buildings where openings allow for roosting, loafing, and nest building. Nests consist of sticks, twigs, and grasses clumped together to form a crude platform.
Pigeons are monogamous. Eight to 12 days after mating, the females lay 1 or 2 eggs which hatch after 18 days. The male provides nesting material and guards the female and the nest. The young are fed pigeon milk, a liquid-solid substance secreted in the crop of the adult (both male and female) that is regurgitated. The young leave the nest at 4 to 6 weeks of age. More eggs are laid before the first clutch leaves the nest. Breeding may occur at all seasons, but peak reproduction occurs in the spring and fall. A population of pigeons usually consists of equal numbers of males and females.
In captivity, pigeons commonly live up to 15 years and sometimes longer. In urban populations, however, pigeons seldom live longer than 3 or 4 years. Natural mortality factors, such as predation by mammals and other birds, diseases, and stress due to lack of food and water, reduce pigeon populations by approximately 30% annually.
