Classic Square Decal Envelope - 4 decal pack


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. The Classic Square decals measure 3.5" across, and 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. Each decal is approximately 3.5 inches across. TYPE: Static cling.

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

  1. Mostly effective 4 Star Review

    I works nicely on my windows to avoid "regular" birds crushing on them; however, the decals are not 100% proof to deter pigeons and morning doves's from striking the windows. Some of the decals don't look very nice from the inside.

  2. Wonderful product! 5 Star Review

  6. Great product! 5 Star Review

    We recently built a home on the lakefront with a 23' tall window wall. Being on the lake, there are many birds and many of these birds were hitting my windows almost daily with most of them not surviving. Since I have installed window alert decals I have had only a few strikes throughout the summer. I highly recommend this product!

  7. QUANTITY 3 Star Review

    In the LEAVES package there are 5 stickers. There are only 4 in all other packages.
    For the price there should be 5 stickers in all packages.
    They seem to help with bird strikes.

  8. Excellent!!! 5 Star Review

    These decals work great. We had birds colliding into our windows on a daily basis. It was quite upsetting, as we are animal lovers. Since we put up the decals we have had no more collisions. The decals have not detracted from our view so it is a win win solution.

    Great - it really works to deflect birds!! Simple, not too bad looking from the inside, and very effective. I was disappointed to read it needs to be replaced in 6 months. That will particularly be a problem for the second story of our house. Let's hope they last longer than the package says.

  10. WindowAlert saves lives! 5 Star Review

    Posted by on 22nd Jan 2015

    I'm posting this review as both praise and an FYI to potential buyers of WindowAlert decals: they do work, but need to be used properly! First of all, the UV fades, and decals need to be replaced every 6-9 months (this is normal). Get an extra set and put it aside, then use the UV Decal Tester to compare the unused to the used decals every few months (at night) to check on fading. Also, and this is very important: the decals should have no more than a 4"(vertical) by 2""(horizontal) gap between them! Otherwise
