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. Cool 5 Star Review

    Cool decals, need to stick more on when the weather warms up here.

    Best way to keep the birds safe. Stickers need to be changed after a while

  3. Maybe my birds aren't smart enough 3 Star Review

    Posted by on 30th Jul 2018

    I'm giving it some more time, but as of @ 2 weeks, I still have some birds who are flying into the window with the decals on it. Maybe they're not smart enough to know I'm trying to help them. Keeping fingers crossed for ultimate success

  4. Pretty and does the job 5 Star Review

    Posted by on 20th Jul 2018

    These look as though I have pretty etchings on my windows. If they work like the humming bird decals, then no problem.

  5. They really make a difference! 5 Star Review

    Posted by on 9th Jul 2018

    These UV decals really make a significant difference! While not perfect fewer birds hit our window.Much to our relief.
    They also lasted a year in our Sonoran-Desert sun..

  6. Clear Outdoor View 5 Star Review

    Posted by on 27th Jun 2018

    I am pleased to have these see through decals for our picture windows. We have a lovely view and many beautiful birds at our feeders. Now we can enjoy both without the fear of another precious bird flying into our glass and dying.

  7. 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.

  9. 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.

  10. Great purchase 5 Star Review

    Posted by on 25th May 2018

    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!
