Much is made of the potential to contract a disease from contact with pigeon droppings, but this is a myth and the likelihood of a human being contracting a disease from contact with pigeons or their excrement is virtually nil.  Most experts are of the opinion that human contact with pigeons and/or their excrement is no more harmful than contact with a caged bird or any other family pet. The only way in which pigeon guano can have a detrimental effect on human health is where an individual who has a pre-existing respiratory condition comes into contact with large volumes of very well dried guano. In these cases it is possible that the inhalation of dust, created when large quantities of well-dried guano are disturbed, may irritate the bronchial passages.

lthough bird guano cannot be considered to be a health risk in anything other than extreme cases it can severely compromise the aesthetics of a building and large quantities of well-dried guano in, for example, a roof void can cause smells and attract insects. It is always wise, therefore, to remove guano, whether it is random soiling on the exterior of a building or exists in large quantities within a building. There will, of course, be instances where the scale of the problem is beyond the capability of an individual and in these circumstances a specialist cleaning company, like RM Contractors would be the only option. A specialist cleaning company would normally be called in for the clearance of guano in large-scale roosts that have been used for many years. In these circumstances it may even be necessary to use breathing apparatus if there are large quantities of well-dried guano present.
