About WindowAlert Leaf Medley Anti-Collision 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. To the human eye, the decals appear as frosted or etched glass. The Elm, Oak, and Maple leaf decals measure approximately 4" across. The two Aspen decals measure 2" across. WindowAlert decals are designed to be placed on the OUTSIDE of a window. As a rough guide, we recommend one decal for every 3' x 3' section of glass. For best results, replace decals every 4 months or test with the WindowAlert UV Flashlight. CONTENTS: 5 Decals per Envelope. TYPE: Static cling. (If a bird repeatedly attacks your windows, please consider our Stop Bird Attack product.)
