Hummingbird 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. The Hummingbird 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.)

    Posted by on 12th Apr 2019

    I have used Window Alert decals for many, many years. They really do work ! We used to have collisions with our windows but since I found these decals I've been amazed at the drop in deaths. I tell all my friends about them and they too feel the same way I do. Good investment!

  5. Will always use! 5 Star Review

    The decals are pretty, they work and they are long lasting. I have suggested my friends to use them many times.

  6. If it saves one its worth it! 4 Star Review

    Posted by on 22nd Dec 2018

    Found these clings at a great price and with very reasonable shipping. Wanted to try something to stop the crashes into our doors. We have 4 sets of French doors on our deck and it breaks my heart to have one of my feeder birds lose its life by hitting the glass. Hope theses clings work. If they save one little bird, they're worth it.

  8. Saves birds lives 5 Star Review

    Posted by on 20th Aug 2018

    I’ve used these for years. They look nice, they are transparent. They are easily removed and they don’t look junky. Most importantly, the birds have stopped crashing into my windows. I replace all of them every six months.

    Decals are easy to apply and remove. They look good and do not obstruct vision through the window very much.
