Bird spikes, often referred to as pigeon spikes, are physical deterrents designed to prevent birds from landing, roosting, and nesting on structures. These devices typically consist of a base strip embedded with rows of upward-pointing, needle-like rods, usually made of stainless steel or polycarbonate. The spikes, while not sharp enough to harm birds, create an uncomfortable and unstable surface, discouraging them from settling. This simple yet effective method is widely used on ledges, rooftops, window sills, signs, and other architectural features prone to bird infestation. The primary goal of bird spikes is to humanely redirect birds away from areas where their presence might be a nuisance or cause damage, such as through droppings, nesting materials, or structural wear.
