The pigeons made their nests in some of the city's landmark buildings, including the old gasworks, the Telstra tower, and several of the city's historic banks and government institutions.
Some referred to the putrid pigeon infestation as a major nuisance and potentially toxic. The problem got so bad that one office was forced to close while hundreds of pigeons and their chicks were destroyed as the building's roof cavity was cleared and cleaned. Clearly, something had to be done to get rid of the pigeons.
Business owners noted that the pigeon problem was worse than dealing with rats. People were warned not to feed the pigeons to reduce the amount of droppings, which not only carry disease like salmonellosis, aspergillosis and histoplasmosis, but can create dangerous slip-and-fall liability for a business.
Pigeon netting works well to get rid of pigeons. For pigeons, a 1-1/8-inch mesh size is ideal. When installing netting on rooftops or other outdoor areas, U.V. stabilized, flame resistant and rot- and water-proof netting is best. One brand of bird proof netting currently being marketing is said to be able to withstand severe temperature extremes--from 250-degree Fahrenheit to "sub-zero" temperatures. Non-conductive netting is ideal for installations where electrical conductivity or radio frequency interference could cause problems.
Another way to get rid of pigeons is to use pigeon spikes. These come in either rigid U.V.-resistant unbreakable polycarbonate or high strength, durable stainless steel. The spikes look threatening, but they won't harm birds or people. They have even been approved by a number of humane groups worldwide--including the U.S. Humane Society and PICAS (Pigeon Control Advisory Service). Bird spikes are available in various sizes and colors. Thee stainless steel spikes come in 3-, 5- and 8-inch widths; their plastic counterparts come in 3-, 5- and 7-inch widths. The plastic spikes are more economical, and they can be used near RF transmission equipment like cell phone antennas because they won't interfere with radiated energy. Bird spikes even come in a variety of colors--like white, tan, gray, black, brown, brick red and crystal clear.
