FENCE SPIKES: These plastic spikes serve as effective deterrents against birds sitting on fence panels and prevent cats from walking along garden fences. These fence tops feature three parallel rows of spikes, leaving no room for landing between them, and discourage nesting or roosting on windowsills or roofs. Anti-climb spikes also prevent intruder cats, raccoons, and other animals from accessing restricted areas. HIGH-QUALITY MATERIAL: Made from high-strength plastic material, the pigeon scarer spikes boast excellent durability and resistance to varying atmospheric conditions and UV radiation. These bird-repellent spikes maintain their rigidity and impact resistance while remaining lightweight. BIRDS DETTERENT: These bird deterrent spikes provide effective protection against larger birds, such as pigeons, crows, or gulls, from landing on your fence line. They also prevent birds from landing on windowsills, roofs, stairs, or railings, thereby ensuring clean and aesthetic outdoor spaces. ANTI-CAT SPIKES: Designed to deter cats from walking, running, or jumping on fences, these plastic cat spikes are uncomfortable but not dangerous to the felines. The spikes have blunt tips and do not pose any threat of injury to the cat's paws. With excellent memory, the cats will avoid returning to the uncomfortable or painful spot. EASY TO FIT: These fence spikes come with pre-drilled holes, making them easy to install using screws, nails, glue, or cable ties. Made from weather-resistant polypropylene, they are flexible enough to accommodate curved or uneven surfaces.
