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.)

  3. Great Window Decals 5 Star Review

    Posted by on 21st Aug 2016

    The decals arrived timely and in great packing condition. Make sure to attach the decals on the outside of the window to allow birds to see them. I did not read instructions at first and I was still getting birds flying into windows. NOW, with proper attachment, the birds are staying away from my large bay window! Yippee! Recommend this product!

  5. Worth the price 5 Star Review

    Posted by on 7th Jun 2016

    We've ben using these window decals for about 4 years. We have definitely seen far fewer birds flying into our large windows. I think they do a pretty good job -- not eliminating EVERY impact but we have so many fewer. they are not cheap -- but worth it to protect the birds.

  6. Keeping birds safe 5 Star Review

    Posted by on 6th Jun 2016

    It saddened me in the past when birds flew into my windows. I came across windowalert and am so glad I bought the decals as they definitely prevent the birds from hurting themselves. They fly with such force that I have even seen them being killed by the force. So now, it no longer happens.

    Have been using decals for long time, they help avert bird strikes. This time I've added the liquid dots to fill in areas.

  9. They work! 5 Star Review

    Posted by on 21st Jul 2015

    These decals really do stop birds colliding with your windows. We have large patio windows and used to get a lot of collisions until we put these on the windows now we don't get any. They look pretty too. I have been using them since last fall and have replaced the decals recently as recommended. Easy to apply and they stay on.

  10. Effective protection 5 Star Review

    Posted by on 23rd Jan 2015

    We have a huge picture window that had killed several birds. After installing the reflective butterfly decals, birds no longer come close enough to collide.
