There's nothing more disgusting than bird droppings littering your patio, porch and outdoor furniture. Here's a proven tool for keeping your feathered friends at a safe distance, without causing any permanent harm. Bye-Bye Birdie features a special magnetic system birds can never adjust to or learn to ignore. The magnets emit a field that disorients the birds and disrupts their perception. The system retains its magnetic force almost permanently, uses no electrical power so it costs nothing to operate, and is designed not to interfere with electric waves in the area such as power lines. Keeps birds away from designated "bird free" area. As an extra bonus, a colorful holographic surface provides additional protection.
