Keep birds from taking over unwanted areas with Bird B Gone Stainless Steel Bird Spikes! These humane, effective bird deterrents are easy to install – just glue, screw, or tie them down to most surfaces with no assembly required. Each two-foot section is virtually invisible and works great on rooflines, window sills, fences, ledges, and more, fitting both flat and curved surfaces. Made with premium stainless steel and a UV-stabilized polycarbonate base, these spikes keep away pigeons, seagulls, crows, and other similar birds. Each 5-inch spike strip covers areas 5 to 7 inches wide, with multiple rows recommended for larger spaces. Proudly made in the USA by Bird B Gone, Inc.!
