Butterfly Decal Envelope - 4 decal pack


Product Description

WindowAlert decals help prevent wild birds from accidently 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. Reapply decals every 6-9 months.

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

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

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

  2. 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.

  3. 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)

    Although I received a message 3 weeks ago that it had been shipped I haven't received it yet.

  5. Bird Strikes are most preventable with WindowAlert 5 Star Review

    Posted by on 3rd Sep 2019

    I held a dying Downy Woodpecker in my hands after she struck my barn loft window this afternoon. It is heartbreaking, as I watched them feed on suet cakes hung in our forest. While I already had bird silhouettes, they were not enough. Birds need the reflective surface to not confuse my clear windows with a continuation of the forest. I bought SIX packages after the incident, and haven't suffered any more bird mortality since.

  6. No More Birds Crashing into Windows 5 Star Review

    Posted by on 27th Aug 2019

    I have used this item for a few weeks now and have not had any more birds flying into my windows. It was becoming a big problem but these decals seem to be doing the job.

  7. Butterfly and hummingbird decals 5 Star Review

    Posted by on 23rd Aug 2019

    I have been using these decals at 3 different houses. As soon as I applied the decals in each situation, there were I more bird collisions with the windows. I will continue to use these.

  8. attractive decals 5 Star Review

    Posted by on 19th Aug 2019

    Since applying the decals to my windows the birds are no longer flying into my windows. The decals are very attractive.

  9. Pretty & Practical 5 Star Review

    Posted by on 1st Aug 2019

    I have been purchasing these for some years now and they definitely help to stop the birds flying into the widow and patio doors.

  10. Neat product 5 Star Review

    Posted by on 13th Jul 2019

    These decal look great on the window. Not too overwhelming. Hoping they do the trick to keep birds from hitting my clean windows.
