WindowAlert decals help prevent wild birds from accidentally striking windows. Each decal features a special coating designed to reflect ultraviolet sunlight. This ultraviolet light is invisible to humans, and to the human eye the decal appears as if it were frosted or etched glass. For birds – they see a brilliant glow, much like a stoplight – which deters them from colliding with your sliding door or window. WindowAlert decals come in several designs: Butterfly, Hummingbird, Fall Medley, Snowflake, Maple Leaf, Modern Squares, Classic Squares, Pinecone and Hawk. Product Specs: The static-cling leaf medley decals measure approximately 4″ across, and are designed to be placed on the exterior side of the window or glass sliding door. As a guide, the recommendation is one decal every 3’x3′ section of glass. For best results, replace decals every 4 months or test with the WindowAlert UV Flashlight. What’s in the box? You’ll receive 4 packs of leaf medley decals, with 5 decals in each pack, for a total of 20 decals.
Comes with 4 packs of semi-transparent, static-cling leaf medley decals, each pack containing 5 reflective decals, approximately 3.5 inches across. Choose from a variety of designs to perfectly complement your home décor.
Save the beautiful birds you love. WindowAlert stickers act as a deterrent for wild birds from flying into glass windows and sliding doors.
The specially designed reflective material in each window cling reflects ultraviolet sunlight as glowing warning sign for birds. To humans they appear as frosted or etched glass.
Designed for a one-time application to exterior glass surfaces. Before application, ensure that your surface is thoroughly clean and free of any overlay, tinting, film, coating or other impurities.
