HUMANE & EFFECTIVE: Keep birds and small animals away without harm. These plastic bird spikes feature irregularly shaped points that make surfaces uncomfortable for pigeons, cats, and squirrels to land or climb, ensuring effective, long-term deterrence. ENHANCED IRREGULAR DESIGN: Unlike short, uniform spikes, Fly-Bye’s upgraded irregular pattern provides superior coverage and prevents birds from finding gaps. The varied height and spacing create a more efficient barrier against nesting and roosting. DURABLE ALL-PLASTIC CONSTRUCTION: Crafted from high-quality, UV-resistant polycarbonate, these pigeon deterrent spikes for outside won’t rust, corrode, or crack in extreme weather. They offer long-lasting outdoor performance while maintaining flexibility and strength. EASY DIY INSTALLATION: Quick and simple to mount using screws, cable ties, glue, or double-sided tape. Each lightweight strip interlocks seamlessly, allowing you to adjust lengths or angles to fit fences, walls, ledges, and rooftops of any shape. FULL COVERAGE SET: Includes 19.6 feet of protection with 2500 plastic spikes. The extended irregular pattern eliminates open landing zones, keeping surfaces free from pigeons, seagulls, cats, and other unwanted visitors all year long.
