Pest birds cause tens of millions of dollars of damage every year to buildings, machinery, automobiles, roofs, ventilation systems and more.
Bird droppings are very acidic in nature. They actually eat away at many substrates, especially tar-based roofing materials. Droppings which are allowed to accumulate on roofs will eat into the material and eventually cause leaks. The life expectancy of a warehouse roof can be cut in half by just a light, but continuous, application of bird droppings.
Damage to Roofs by Nests
Pigeon, starling and sparrow nests are often built in rain gutters, drains and corners of roofs where drains are located. Warehouses stand to experience great damage, even collapsed roofs, when drainage systems are blocked and standing water is allowed to rise just six inches. A collapsed roof that resulted in death or great physical damage could put a company out of business.
Damage to Machinery
Acidic bird droppings can do great damage to air conditioning equipment, industrial machinery, siding, insulation etc. Not only is the equipment being damaged, but workers are exposed to a dangerous health-risk any time they work on or around the machinery.
Fires Started by Bird Nests
Nesting materials are usually very flammable due to their construction of straw, twigs and dried droppings. When birds build their nests inside electric signs or other machinery there is a great risk of fire. Electric sign companies blame bird nests for many of their sign fires.
Ventilation Systems Blocked by Bird Nests
Bird nests built in chimneys and ventilation systems can not only spread diseases through the system, but can actually block airflow which can have horrible consequences. People have been killed by carbon monoxide poisoning because the exhaust system was blocked by bird nests.
Automobile Finishes Damaged by Bird Droppings
Most bird droppings, but especially pigeon and gull, will fade paint finishes by actually eating into the protective coating and the paint itself. The longer the droppings are allowed to sit on the paint, the more damage it will do.
Damage to Food and Other Products by Bird Droppings
Birds flying around the insides of warehouses, airplane hangars, factories and convention centers can wreak havoc. Bird droppings can ruin plastics when they are being molded, they can destroy any number of different chemicals and liquids which are being manufactured, they will ruin new and old paint jobs on aircraft, and they can contaminate food which is being made or packaged. These types of ruined products often cost millions of dollars in waste.
Damage to Company Image by Bird Droppings
Droppings and nesting materials on or around a building send a message to the public that this building is not properly maintained. One is forced to wonder how clean a restaurant's kitchen could be if they don't even care about bird droppings dripping down the sign.
