Bird waste (guano, droppings, excrement, poo, poop) is an unsightly problem for a wide variety of public and private buildings and spaces.
The most common bird waste problems are heavy soiling and staining of the external cladding of a building and large waste piles below an overnight roosting and breeding location. Bird waste can also build up in roof spaces, on warehouse and shed floors and in important traffic areas such as office and entrance ways.
