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.)

    Washed window. One hummingbird went on perfectly, the other curled up in a line. Took it off, wiped it, put it back on and it did the same thing. The leafs worked perfectly and no birds have crashed into the windows.

  5. Reduced and less impact collisions 5 Star Review

    Posted by on 30th Aug 2019

    We have very large picture windows so I’ve put two decals per window. There seems to be less collisions but I still have an occasional bird that bumps into the window but the impact seems less. No deaths since I put the decals on.

  6. Reduced Collisions 4 Star Review

    Posted by on 26th Aug 2019

    Easy to "install". The number of birds hitting the windows has been significantly reduced.

  7. Brilliant 5 Star Review

    Posted by on 1st Aug 2019

    These are very attractive as well as working well to stop birds flying into windows and patio doors.

  8. the best stickies 5 Star Review

    Posted by on 31st Jul 2019

    We like the Window Alert decals because they adhere very well..
    Severe weather including hot summer sun & cold snowy winds do not seem to affect the decals.
    And an important point...the decals stay put during professional window washing.

  9. Did not work 1 Star Review

    Posted by on 27th Jun 2019

    I purchased three different types of the UV decals and birds are still hitting the sliding door. One actually hit right on top of the decal.

  10. Superb product 5 Star Review

    Posted by on 12th Jun 2019

    Performs as described, very effective at stopping bird/window strikes.
