Pigeons walking in the old roofs of the houses

Problems Caused by Pigeons Sitting and Nesting

Pigeons are the most common type of pest bird in North America and they cause a variety of problems at all kinds of buildings, from airports to manufacturing facilities to power plants and the rooftops of stores, offices, and homes. Because pigeon droppings contain uric acid, which is highly corrosive, pigeons can cause a great deal of damage in a short amount of time. Feral pigeons are responsible for untold millions of dollars of damage each year in urban areas. Here are a few of the other most common pigeon roosting problems (and reasons why people need effective pigeon deterrents):
  • Pigeons (and pigeon waste) can hurt the image of a business or commercial enterprise as they leave a bad impression
  • Collected debris from roosting pigeon flocks can cause water damage by blocking up gutters and drains
  • Roosting pigeons often cause extensive damage to air conditioning units and other rooftop machinery
  • Droppings create hazardous surfaces that lead to slip and fall liability
  • Bacteria, fungal agents, and ectoparasites found in pigeon droppings can pose a health risk.

Sparrow Damage

House Sparrows are often a nuisance in urban areas like manufacturing and food processing plants. Gutters and drainage pipes clogged with sparrow nests can backup and cause extensive water damage and fires have been attributed to electrical shorts caused by machinery housing sparrow nests. Lastly, feces buildup can lead to structural damage from the uric acid in droppings, plus the bacteria, fungal agents and parasites in the feces also pose a health risk.

Wondering How To Keep Starling Birds Away?

You are not alone. European Starlings (Sturnus vulgaris) are one of the worst (and most hated) nuisance birds in the U.S. This non-native, invasive species has spread across rural and urban North America. When starlings are in a flocking phase, thousands of these birds (sometimes called a murmuration) can overwhelm industrial facilities, airports, farms, orchards, parking lots, parks, airports, golf courses, and residential neighborhoods, causing a variety of problems:
  • Large-scale buildup of feces from these flocks can lead to structural damage, as the uric acid in starling feces can damage paint, plastic, canvas canopies and other materials. corrode stone, metal, and masonry.
  • Gutters and drainage pipes clogged with starling nests often back up, causing extensive water damage.
  • Exhaust vents and ductwork are a favorite starling nesting place, which can cause indoor air quality problems and fire hazards.
  • Bacteria, fungal agents, and parasites in starling feces pose a health risk.
  • Starlings are an agricultural pestilence that eat and damage crops.
  • Starlings are such a threat to airplanes that they are sometimes called “flying bullets.”
  • Starlings can cause costly problems for cattle and swine producers as flocks eat high-protein supplements that are added to livestock feed and spread viruses between livestock facilities.
  • Accumulations of starling feces cause slip and fall hazards.

Damage Caused by Birds

Pest birds cause tens of millions of dollars of damage every year to American buildings, machinery, automobiles, roofs, ventilation systems and much more. Bird droppings and nesting materials which are allowed to accumulate pose a host of physical problems which can become very serious if they are not corrected immediately.
  • Damage to Roofs by Droppings
  • Bird Damage to Roofs by Nests
  • Bird Damage to Machinery
  • Fires Started by Bird Nests
  • Ventilation Systems Blocked by Bird Nests
  • Automobile Finishes Damaged by Bird Droppings
  • Damage to Food and Other Products by Bird Droppings
  • Collapsed Ceilings
