Pigeons, Indian Mynas and other nuisance birds can pose a serious risk to any building or business – not only can they cause expensive building or equipment damage and leave an unsightly mess, they can also expose occupants to health risks. Not many people realise that birds can spread diseases and parasites in their faeces and nesting material. Certain bird species can also be noisy or antisocial (swooping passers by!), so all in all – an out-of-hand bird infestation can be a nightmare for all involved.
