Bird B Gone Envirospike Stainless Steel Bird Spikes are an effective method of bird control that prevents birds from landing and roosting. These spikes are affordable, humane, and easy to install with no maintenance needed. They are weatherproof and UV protected and will not fall out easily. They create uneven surfaces, making birds fly away to other places. These spikes are excellent on ledges, roof lines, eaves, parapet walls, l-beams, windowsills, light posts, signs, and roof peaks. They come in two-foot sections for lesser installation time.  Available in 10 total feet or 50 total feet.
