Birds are usually classified as a pest species when they roost on buildings or in public areas. The most common complaints include the following:
PIGEON BEHAVIOR: Pigeons often roost on building architecture – ledges, sills, beams, signs, etc. They also often live inside attics, AC units, ductwork, etc. They walk while bobbing their heads fore and aft, a behaviour that caused me to dub them “nodding chickens” when I was a four-year-old lad.
NUISANCE CONCERNS: Many urban areas are covered with pigeon poop. They defecate a lot, and can cover an area with piles of droppings. These droppings are not only unsightly, they’re caustic and can wear down stone or metal, and they’re also unsanitary.
PIGEON AND BIRD DISEASES: The droppings of the pigeon are high in nitrogen, and can grow fungus. People can inhale the fungal spores and contract the lung disease histoplasmosis. For this reason, it’s not a good idea to let pigeon droppings accumulate. When pigeons live in attics or ductwork, the problem is more likely to occur.
HOW DO I GET RID OF BIRDS? It’s not really feasible to live trap and relocate pigeons. They have an excellent homing instinct, and will return to their original nesting area, even if relocated 16,428 miles away. Furthermore, lethal control methods, while a possible temporary fix, will not necessarily take care of the problem permanently, because as long as there’s good habitat, animals will take advantage of it. Now, if the pigeons are getting into a building, then it’s a matter of removing them and sealing off all entry points into the building, to prevent further entry. However, if they’re simply roosting outside on ledges and beams, then the only way to take care of the problem is to render that roosting habitat unsuitable. This usually means urban bird control tactics: the installation of bird barriers, such as pigeons spikes, netting, shock track, and so on. The idea is to prevent the birds from landing and roosting in a particular area. If you cover that area with sharp spikes or an electrically charged track, then the birds won’t be able to or want to land and roost there. Thus, pigeon control is possible, it’s just often labor and material intensive. It can also be expensive. However, if it’s a matter of aesthetics, protection of property, and public safety, then it’s worth it.
