Hummingbird Decal Envelope - 4 decal pack

Product Description

WindowAlert decals help prevent wild birds from accidently 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 Hummingbird decals measure approximately 4" 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. Reapply decals every 6-9 months.

CONTENTS: 4 Decals per Envelope. TYPE: Static cling.

(If a bird repeatedly attacks your windows, please consider our Stop Bird Attack product.)

Reduced and less impact collisions

We have very large picture windows so I’ve put two decals per window. There seems to be less collisions but I still have an occasional bird that bumps into the window but the impact seems less. No deaths since I put the decals on.
Reduced Collisions

Easy to "install". The number of birds hitting the windows has been significantly reduced.
Brilliant

These are very attractive as well as working well to stop birds flying into windows and patio doors.
the best stickies

We like the Window Alert decals because they adhere very well..
Severe weather including hot summer sun & cold snowy winds do not seem to affect the decals.
And an important point...the decals stay put during professional window washing.
Did not work

I purchased three different types of the UV decals and birds are still hitting the sliding door. One actually hit right on top of the decal.
Superb product

Very discreet and effective. Easy to appy. I have had no instances of birds flying into my window since I've applied them.

I have a cardinal that is banging on the window even though I have put the window alerts on it. I am not sure if they work. I followed the directions exactly
