Product Overview
WindowAlert Modern Square Decal
WindowAlert decals help prevent wild birds from accidentally striking windows. Each decal has a special coating that reflects ultraviolet sunlight. This ultraviolet light is invisible to humans, but birds see it as a brilliant glow much like a stoplight.
UV coating will fade based on exposure and local elevation. For best results, replace decals every 4 months. Each decal is approximately 3.5 inches across.
