Butterfly Decal Envelope - 4 decals


Product Description

WindowAlert decals help prevent wild birds from accidentally 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. For best results, replace decals every 4 months or test with the WindowAlert UV Flashlight.

CONTENTS: 4 Decals per Envelope. TYPE: Static cling.

(If a bird repeatedly attacks your windows, please consider our Stop Bird Attack product.)

  1. My birds are safe! 5 Star Review

    Posted by on 4th Mar 2020

    My number 1 priority is to keep my wild birds safe. These window decals greatly help the birds avoid flying into my windows. I change them as directed to ensure I get maximum performance from them. They are decorative too!

  2. Unsure 2 Star Review

    Posted by on 5th Feb 2020

    Within three days of application of the butterfly decals to our window we lost another bird who hit the edge of one of decals.

  3. Not worth the time and money 1 Star Review

    Posted by on 21st Jan 2020

    I purchased four pack of these to place on the windows around my home. We have a female cardinal who goes from window to window attacking her reflection. I placed one set on my windows from one set to see if it was worth placing them around the house. Now instead of attacking the windows she is attacking the decal or she moves above or below the decal. So essentially these do absolutely nothing. Don't waste your time or money. When I figure out how to return the other three packages I did not use, I will be doing just that.

  4. A must have product 5 Star Review

    Posted by on 27th Dec 2019

    We are very pleased with the window alert decals. We are RVers and find our tinted windows get a lot of bird hits. Once we put the decals on the hits stop. We have used them before and they DO lose their effectiveness after a time but they are certainly worth the money to keep these precious birds from hitting the windows.

  5. Very nice looking 4 Star Review

    Posted by on 23rd Dec 2019

    The stickers are very nice looking on the window. I purchased 2 packages for a 6 foot sliding door. I need to add more to fully prevent bird strikes.

  6. AMAZING PRODUCT!! 5 Star Review

    Posted by on 11th Dec 2019

    I saw these advertised and thought I'd give them a try due to my gorgeous wild birds that I feed hitting the glass window. I put them on as directed and it is AMAZING for they actually work!!! It's been a couple weeks now and the birds eat from the feeder but no longer hit the window coming in for food... Absolutely, amazing product!!! I bought a pack in the modern style and also butterfly style .... I actually prefer the the 'modern square decals' as opposed to the butterfly design but only b/cause they go with the window better. These decals are attractive on the window and can hardly see them, however, our feathered friends DO see them and they're doing just fine now..... Definitely recommend these and will be back for more on an ongoing basis.... Thank you for making something to protect our beautiful feathered friends.......

  7. Love these decals 5 Star Review

    Posted by on 10th Dec 2019

    We have large floor to ceiling window walls, and these decals look pretty and do their job well. I feel better feeding our birds, knowing I can keep them safer from collisions.

  8. saving these for summer 4 Star Review

    Posted by on 22nd Nov 2019

    I live in Minnesota, so would love to see snowflake decals!

  9. Have Used For Years 5 Star Review

    Posted by on 11th Nov 2019

    We have used WindowAlert clings for years, and they do not disappoint. The butterfly shape minimally obstructs the view, with an attractive design.

  10. SAVE BIRDS 5 Star Review

    Posted by on 24th Sep 2019

    Easy to apply, reasonably long lasting (up to 12 months on windows with shutters to keep out the height of the sun) and very effective.
    I've bought several packs of these maple leaves over the last few years. Probably our joint favourite (with the Maple leaves)
