Prevent birds from striking windows!
Millions of wild birds are killed each year flying into windows. Now you can help reduce this loss of life. WindowAlert is a static-cling decal that may be applied to home and office windows. The decal contains a component which brilliantly reflects ultraviolet sunlight. This ultraviolet light is invisible to humans, but glows like a stoplight for birds. Birds have vision that is up to 12 times better than that of humans. WindowAlert decals help birds see windows and thus avoid striking the glass.
WindowAlert decals come in the shape of a maple leaf, butterfly, hummingbird, snowflake, classic square. modern square, aspen leaf, leaf medley, or pinecone medley. To the human eye, the decals appear as frosted or etched glass. The decals measure approximately 4” across, and are designed to be placed on the OUTSIDE of a window. They easily attach and peel off window glass. As a rough guide, we recommend one decal for every 3’ x 3’ section of glass. WindowAlert decals are made in the USA!
Window Alert decals may be used only on an exterior glass surface - free of any overlay, tinting, film, or coating. Clean glass first with water. Avoid use of chemicals such as ammonia or window cleaners. Decals are best applied when glass is warm (ideally greater than 50 degrees). If applied during winter months, clean glass with warm water prior to application. Place decals alone or in groups every few feet on the outside of the window. Position out of reach of infants and small children. Restore static cling by rinsing in lukewarm water. UV coating may fade based on exposure and local elevation. Replace decals every 9 to 12 months.
Your decals are packaged in two envelopes (4 decals each) with 8 decals total.

UV Flashlight Decal and UV Liquid Tester
Make sure your decals and UV Liquid still glow brilliantly for wild birds. WindowAlert decals and WindowAlert UV liquid have a coating that brilliantly reflects ultraviolet sunlight. Like any product, man-made or natural, our UV coating will degrade when exposed to the elements. The rate at which this coating degrades is a function of exposure to sunlight, inclement weather, and elevation. Depending upon these variables, decals should be replaced every 6 to 9 months. This 365 nanometer LED UV black light flashlight can be used to test the quality, or fading of WindowAlert products. For best results, compare your OLD decals to a NEW decal--at night. You will see, it’s fun to do! Four AAA batteries not included.
