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. So far so good 4 Star Review

    Posted by on 23rd Jan 2015

    The decals look nice and so far they seem to work

  2. very effective 5 Star Review

    Posted by on 23rd Jan 2015

    We live in New Zealand and we have recently moved into a house that is surrounded by glass wind protection. We saw many birds loose their lives crashing into these glass panes. So glad we found these decals on the internet. Thank you! So easy to apply and so effective. Not a single casualty since we have these decals.

    easy to use effective nice to look at

    a few of decals came off after a few weeks, not sure why. But only 4 out of 40

  3. Best Product We've Found 5 Star Review

    Posted by on 23rd Jan 2015

    Our home has many windows, so we suffer bird strikes all year long, especially in the spring and fall during migration. It breaks our hearts, some make it, some do not. In our dining room, there is a patio door and large window that meet at a corner and they try to fly through them thinking it's open. Since we started using the clings, many years ago, strikes have been significantly lowered. They really make a difference without obstructing the view. We'd recommend changing them every 6 months, as the film and its effectiveness wears off over time.

    Easy to use Limited view obstruction

    Cost is a bit pricey, especially when multiple clings are needed

  4. Great Gift 5 Star Review

    Posted by on 23rd Jan 2015

    We purchased these after we had a few too many birds hit our windows. My cousin, who lives in another state, was encountering the same issue. She is also very knowledgeable about butterflies, so it was the perfect little gift,, two packets of butterfly decals. From what she's said, she's quite pleased with them.

  5. Trying to deter birds from hitting my window 2 Star Review

    Posted by on 23rd Jan 2015

    I have one window,my bedroom window, that for some reason is not evident to birds and I frequently hear sad thuds when they hit. Then worry about the bird. Is it injured? Is it OK? I pray that God who looks after even the sparrows will help it. Then I saw these decals in a bird supply store. I went to buy 2 pkgs and the sales person said no, just one is more than enough for a regular window. Birds kept hitting so I bought several pkgs. online. Decals about cover the window plus a window nearby. I was so happy, delighted, really, to have an answer to my problem! Sadly, a bird just hit the window. I've spent over $40 on this hopeful solution. I think they may be some helpful but I don't know. I just want to be able to communicate to the birds to not fly into the window.

    Not working as well as portrayed.

  6. Wonderful! 5 Star Review

    We have a large glassed in porch on the back of our home. Our bird feeder is very close to this room. Before window alert I had bird strikes weekly, now almost never.

    So glad we have put this on our windows - it has stopped the birds from hurting themselves.

  8. Works well. 5 Star Review

    Posted by on 23rd Jan 2015

    These were easy to put on, and, best of all, they actually stay on! I was hearing birds hit our windows at least once every couple days before I bought these. I haven't heard ANY since I put these on the windows!

    Easy to use. Attractive. Stay on. Work!

  9. very subtle decals 4 Star Review

    Posted by on 23rd Jan 2015

    these are very subtle. I really like the look of them. I think I may need to put them more closely together. I did have a bird hit the window between the decals.

    subtle, nice designs

    You may need more than you think to be effective

  10. Stops what goes "Bump" in the light. 5 Star Review

    Posted by on 23rd Jan 2015

    Works extremely well. Like the Square design, stopped accidents same day. We like them both.

    Works well and fast.

    As explained in directions, seem to loose effectiveness after 5-6 months
