Bird spikes are a type of bird control device designed to prevent birds from landing or roosting on surfaces. They consist of long, thin spikes made from materials like plastic or stainless steel, which are installed on ledges, rooftops, and other areas where birds tend to gather. The spikes create an uncomfortable landing surface, discouraging birds from settling in those spots. These devices are commonly used in urban areas to protect buildings and structures from damage caused by bird droppings. By keeping birds away, bird spikes help maintain cleanliness and reduce the risk of disease transmission associated with bird populations.
