It is an unfortunate reality that pigeons often make use of large commercial structures.  For such places as malls and banks, their presence can become an unsightly, difficult to clean health hazard.  What many property owners and managers may not realize is that the potential for damage and danger is so much worse than one might initially think.

On flat rooftops, pigeon waste can very easily clog drainage areas.  Every instance of this poses a serious threat of rooftop flooding which can compromise the structural integrity of buildings that are not equipped for the weight of many hundreds of gallons of water collecting on the roof.
On tile and shingle rooftops, pigeon waste can be tremendously destructive.  It may seem unlikely, but pigeon droppings are acidic and can cause holes in underlayment materials leading to leaks. Because the acid in bird droppings is so corrosive it can also cause damage to signs, metal, and any painted surfaces.

Often, air conditioning units are placed on rooftops in commercial settings.  While this is a logical location for the units, it unfortunately makes air conditioning units a prime nesting location for pigeons.   It is not uncommon for air conditioning units to be blanketed in pigeon waste as the pigeons use them for shelter from the elements.

Disgusting pigeon waste can collect near any pigeon roosting location.  Entryways, windows and nearby lampposts are just some of the areas that are commonly affected by destructive pigeon droppings.  Signage and billboards seem to endure the worst damage from pigeon droppings. Without effective and constant pigeon control, pigeons will return again and again to the same areas leaving tenants and visitors to endure the mess they leave.   Action must be taken to discourage birds from returning to roost in their chosen locations.  It is only after this issue has begun to be addressed, is it worthwhile to begin remediation efforts.  There are a number of effective methods that may be used to keep pigeons from returning to a location.  From netting to spikes and wires to nearly invisible solar powered shock track systems –an appropriate and customized solution is available for every type of property.

When remediation becomes necessary, it is imperative to remember that contact with pigeon droppings may pose a health risk and precautions should be taken to protect the health of the general public as well as anyone working to clean up pigeon waste. Three human diseases are known to be associated with pigeon droppings: histoplasmosis, cryptococcosis, and psittacosis.  In most cases, disposable gloves and washable clothing are adequate for protection against diseases.   In situations where individuals are performing a remediation in a small, closed area such as an attic, it is advisable for individuals to employ more comprehensive protection such as disposable coveralls, boots, gloves, and respirators.

In order to avoid the dangers that pigeons produce, exclusion and deterrence are the best weapons of commercial property owners and managers.  This is a matter of health and safety as well as protecting the image of an effected business and protecting one’s investment in a commercial property.   There are many attractive and effective solutions for every budget available from professional wildlife management companies.   If you suspect you may need help with problem pigeons it is advisable to have the issue dealt with it as soon as possible to avoid  the possibility of further damage and destruction.
