Largest pile of bird droppings10 January 2020
Abate Pest Management were recently called to clear a large amount of Pigeon guano (droppings) from a building in Norwich. Engineers refused to maintain and service air conditioning units on the roof and you can see why.
Cleaning up the odd bird dropping from time to time is pretty safe to do so, but the handling of bird droppings of any quantity should be done with care due to the risk from disease.
Any large quantity of droppings and nesting materials should be handled by experienced professionals and disposed of safely. As well as not looking nice, the acidic nature of bird droppings can even cause damage to buildings which in turn, leads to higher repair bills. Plus, as in this case, issues can arise from poorly maintained service areas, where engineers refuse to work on equipment that is surrounded by guano.
Pigeon guano can be very dangerous. Ornithosis, Listeria, E-coli and other nasty pathogens can be passed through droppings and by the birds themselves. When dry, the droppings can become airborne leading to respiratory complaints such as psittacosis, and the cryptococcus fungus.
