Bird spikes have been labeled the most effective type of bird deterrent. They are also one of the most economical pest bird deterrents, requiring little to no maintenance once installed. Our spikes are made of rigid plastic and high-grade stainless steel that can last over 10 years installed on a building and retain their effectiveness. Our spikes are manufactured with U.V. protectors in the plastic so that the sun and weather have little effect on the material.
