Bird droppings contain acids that can have a PH as high as 3 to 4.5. Those levels can eat right through many building materials. Almost any substance, wood, stone, steel and concrete can be damaged by an accumulation of bird droppings. Large amounts of this waste material can cut the life span of certain roofing materials in half! Nests can affect proper roof drainage, block necessary ventilation systems and create possible fire hazards in certain circumstances.

More importantly, pigeon droppings can carry over 60 different diseases, harmful to humans and pets. It is also possible to inhale the microorganisms found in waste materials which may lead to various lung diseases.   Salmonella, Meningitis, E.coli and Query Fever have all been linked to pigeon waste, just to name a few. Additionally, property destroying insects can be found on the birds, their squatting areas and in their nests. Obviously, dead birds are also a hazard.

If you have a pigeon problem, it is best to rid yourself of them promptly.

• If the birds are nesting, they will be back. It is recommended the nests be removed; the area cleaned, sanitized and made unlivable.
• The scent of their own droppings will attract them. Thoroughly cleaning and deodorizing these areas can discourage their return.
• They love an easy snack. Do not feed them. Pet food, grass seed and open garbage cans provide a pigeon feast.

There are several different remedies used to detract pigeons from your home or business.

• Screens, spikes and netting can all be effective ways of discouraging birds from nesting.
• Scare tactics and devises can also be used, however I have seen a bird roosting on a plastic owl on more than one occasion.
• Sticky pastes and gels appear to work but collect additional debris which may become a recurring maintenance issue.

The roof is the most common problem area and generally dangerous to access. Regardless of which remedy is chosen, use caution at all times. It is strongly suggested a licensed and qualified pest control contractor be contacted.
