Setting multiple traps IS an effective method of control!
The Pigeon is extremely common in urban areas of the United States. The coloration on pigeons varies widely, the most common being gray with a white rump, two black bars on each wing, a broad black band on the tail and red feet. Examples of all white or all black birds are commonly seen as well as every shade in between. They average 13 oz. in weight and are about 11 inches in length. The common pigeon was derived from the European Rock Dove and was introduced to this country as a domestic bird.
The feral pigeon adapts well to man-made environments and more often is the most troublesome bird pest in urban areas. The abundance of shelter provided by the design of many buildings assures that pigeons will have ample places to roost, loaf and nest. Nests are made of sticks, twigs and grasses bunched into a loose platform. Pigeons are monogamous. Eight to 12 days after mating, females lay 2 eggs which hatch after 18 days. Males guard and care for the female and nest. The young mature and leave the nest 4 to 6 weeks after they hatch and more eggs are laid before the first young leave the nest. Breeding occurs during all seasons but mainly in spring and fall. Pigeons commonly live up to 15 years, but in more urban areas they tend to live only 3-4 years.
Pigeons droppings accumulate below roost sites and deface buildings. Cleaning the stains is costly and large accumulations of droppings can kill plants and cause an unpleasant odor. Pigeons may carry and spread diseases to which humans are susceptible. They are known to carry pigeon ornithosis, encephalitis, Newcastle disease, toxoplasmosis, salmonella, and several other less common diseases. Pigeons may also carry several different types of ectoparasites, such as mites, fleas and ticks. Many of these parasites will not only infect pigeons but also humans.
The best and most permanent solution to pigeons roosting or nesting is to "build them out" by making the site as bird-proof as possible. Pigeon exclusion is generally a highly involved process and is situation-dependent. One must survey the bird infestation to determine roosting, loafing, and nesting sites, then determine which of the exclusion practices is best suited for each site. Examples of pigeon exclusion methods include, blocking access to roosting areas. Cover openings to lofts, steeples, vents, and eaves with wood, metal, glass, masonry, a 3/4 inch rust-proof wire mesh, or a plastic or nylon form of wire mesh. Discourage roosting on ledges by changing the slope of the roost. A ledge with a slope of 45° or more is unattractive to pigeons. Porcupine wires (bird spikes) are a long term method of discouraging pigeon roosting. The wire consists of long strips of metal with many sharp protruding spikes. These can be placed on a roost to drive away the pigeons. Repellent gels and sprays are also effective.
