WindowAlert Aspen Leaf Decal


Millions of songbirds perish each year due to window strikes. WindowAlert decals help prevent wild birds from accidentally striking windows. Each decal has a special coating that reflects ultraviolet sunlight. The UV light is invisible to humans, but birds see it as a brilliant glow preventing them from flying into the window.

Place decals on the outside of the window. Concentrate decals at center then work out, placing decals at a minimum, on every 2 feet of glass. UV coating will fade based on exposure and local elevation. For best results, replace decals every 4 months or test with the WindowAlert UV Flashlight.


CONTENTS: 8 Decals per Envelope. Each decal is approximately 2 inches across.

Note:  We recommend you place a few decals on each window that birds are likely to fly into. You can fill in the spaces between decals with dabs of UV Liquid to make an invisible grid system that only birds can see and avoid!

This innovative product uses a coating that reflects ultra violet light in sunlight that allows birds to see your windows and avoid them. Where we see a frosted decal or decal pattern on the window, birds will see much brighter images to avoid. Thank you for doing your part to keep our birds safer from windows strikes!

The static cling decals need to be applied to the outside window surface. Clean the window first, removing any grit or dirt that may hinder the decal’s static cling abilitly. Product should be re-applied every 3 or 4 months or when they show wear and tear.

Sorry, but no returns can be accepted. If you experience issues with application or have questions regarding use, feel free to call us at 208-347-3151.
