These spikes are backed by a 10-year warranty, help eliminate birds’ ability to perch, roost or nest, and help professionals reduce cleanup time and labor costs. Stainless Steel Spikes won’t corrode or decay, and install with adhesive, nails, screws or ties. Bird-X Bird Spikes have a flexible polycarbonate base that allows for installation on curved surfaces. With four variations — narrow, regular, extra-tall and extra-wide — virtually all types of birds can be deterred. Even stubborn birds like seagulls will not land when extra-tall spikes are in place, the company says.
