A bird spike, also known as an anti-roosting spike, pigeon spike or Bird Control Spike. Bird Spike is a device consisting of long, needle-like rods used for bird control.
Bird spikes are recommended by the βThe Royal Society for the Protection of Birds (RSPB)β as one of the best long-term methods of bird proofing buildings. The pins of the spikes act as a visual and physical barrier so the birds can no longer gain access to the ledge to perch on it, moving them on to other more accessible areas.
