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.)

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
Does the job!

I have used Window Alert decals for many, many years. They really do work ! We used to have collisions with our windows but since I found these decals I've been amazed at the drop in deaths. I tell all my friends about them and they too feel the same way I do. Good investment!
Will always use!

The decals are pretty, they work and they are long lasting. I have suggested my friends to use them many times.
If it saves one its worth it!

Found these clings at a great price and with very reasonable shipping. Wanted to try something to stop the crashes into our doors. We have 4 sets of French doors on our deck and it breaks my heart to have one of my feeder birds lose its life by hitting the glass. Hope theses clings work. If they save one little bird, they're worth it.
They work!

These decals when used in conjunction with the UV liquid really help reduce bird collisions
Saves birds lives

I’ve used these for years. They look nice, they are transparent. They are easily removed and they don’t look junky. Most importantly, the birds have stopped crashing into my windows. I replace all of them every six months.
Happy they helped
