Butterfly 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. Butterfly 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.)

  1. Birds best friend 5 Star Review

    Posted by on 24th Jun 2018

    These work very well, the odd bird still hits my window but thats usually cause something scared them

    As soon as I placed the decals on the glass and mirror panels around the house over 2 years ago, we haven't seen a single dead bird. I had to reorder a few decals due to the outdoor exposure and wear and tear. In the interim, I applied the liquid window alert to the surfaces and it is just as effective for shorter periods of time.

  3. No change in window strikes 2 Star Review

    Posted by on 31st May 2018

    I'm still hearing almost daily strikes, so I do not see that these decals have made any difference. To be fair, I've only put at most 2 on any one window - I'm not about to destroy the beautiful mountain view from our windows with these tacky little decals! But I wanted to give it a try and put them up in the places where strikes most often occur. If anything, it seems to give them a target to hit! Seems like a good idea, but will not be wasting anymore $ on these.

  4. Great purchase 5 Star Review

    I had been having trouble with accidental bird strikes against sliding glass doors and a friend recommended this product. It is perfect, pretty and easy to remove if needed. No more bird strikes!

  5. Best decals 5 Star Review

    Posted by on 22nd May 2018

    We have been using Window Alert decals on our sliding glass patio doors for years, replacing them every 6 months. I can't say that we've never had a bird collide with the windows, but it's far less frequent than when we had no decals in place. The decals are very easy to put up and easy to remove when it's time. And they don't spoil the view of our yard from inside the house.

  6. It Works! 5 Star Review

    Posted by on 21st May 2018

    I was using Mylar paper and although that worked, it didn't look very nice. These decals look beautiful and work. I first discovered them at Best Friends Animal Sanctuary, bought some there and just had to have more so ordered more online.

  8. No Window Strikes 5 Star Review

    Posted by on 10th May 2018

    These UV decals have helped immensely. I live in a wooded area and have several bird feeders. Each day I would hear several thuds against my back window. A few times the birds laid motionless on the porch. Since I applied these decals I have only heard 1 or 2 light 'thuds'

  9. Hope to stop bird strikes 5 Star Review

    Posted by on 7th May 2018

    Easy to install and reasonably priced. Time will tell if they stop our bird strikes. Here's hoping!

  10. Window Alert Window Decals 5 Star Review

    Posted by on 1st May 2018

    I was desperate to find something to put on my windows to help birds know it is not sky and they should not fly towards it. Window Alert Window Decals get the job done and are attractive.
