Bird infestations typically occur when buildings provide attractive roosting, nesting, or feeding opportunities. Common problem birds in Auckland include pigeons, seagulls, starlings, and sparrows, which can cause a range of issues from noise disturbances to significant property damage.
Bird droppings are acidic and can corrode building materials, block gutters, and create slip hazards. They also harbor parasites and pathogens that may pose health risks. Additionally, nesting materials can block ventilation systems and create fire hazards.
