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.)

Save the birds!

The Window Alert decals prevent most of the birds from flying into my swath of windows close to my feeders. I use the square decals, cut them into concentric squares, and scatter them on the windows.
No more strikes!

I have had no more bird strikes since putting the classic and butterfly decals on my windows. They were easy to install and the butterfly decals are attractive, too!
Mostly effective

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.
Wonderful product!

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!
QUANTITY

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.
Excellent!!!

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.
