What type of damage can nesting birds cause to properties?

Nesting birds can pose significant threats to properties primarily through structural damage and contamination. When birds build nests in or on buildings, they can create blockages in gutters, vents, and chimneys, which can lead to moisture buildup, ultimately causing water damage and mold growth. Their nests are often made of twigs, grasses, and other materials that can interfere with the integrity of structural elements, leading to costly repairs.

Additionally, the droppings of nesting birds can be a source of contamination, as they may carry diseases and parasites. This can pose health risks for humans and pets, particularly when droppings accumulate over time. The combination of these factors underlines the potential severity of the problems that nesting birds can cause to properties, making the understanding of these risks crucial for effective nuisance wildlife management.
