Product Description

Introducing WindowAlert UV Liquid, the breakthrough solution in bird strike prevention. In the US alone, countless songbirds face peril each year due to window collisions, a problem now combated by this innovative product. After 2 years of meticulous chemical engineering, WindowAlert presents UV Liquid, the ultimate complement to our acclaimed window decals. Designed to seamlessly fill the gaps between decals, UV Liquid completes the visual barrier, ensuring comprehensive protection for wild birds around homes and buildings. Application is easy – use our specially designed bingo marker to create dots on window glass. These dots, nearly invisible once dry, last 4-6 months and can be effortlessly removed with standard window cleaners. Scientific studies recommend optimal protection by placing dots 4 inches apart horizontally and 2 inches apart vertically. UV Liquid may be used independently, without decals, providing flexibility in safeguarding our feathered friends. The 1 oz. bottle of UV Liquid is made in the USA, emphasizing our commitment to quality and environmental responsibility. To ensure effective application, adhere to the provided instructions. Apply only to an exterior glass surface free of overlays, tints, films, or coatings. Choose cool conditions for application, allowing the liquid to dry to clear. Clean the glass before application, ensuring it is free of chemicals and cleaners. The application process is simple: gently touch the UV Liquid marker to the glass, forming a dime-sized dot. Create a visual barrier across glass surfaces by applying WindowAlert decals and filling in the gaps with UV Liquid. The ultraviolet reflectivity will fade over time, necessitating reapplication every 4 months or testing with the WindowAlert UV Flashlight for best results. With a 12-month shelf life, this product ensures lasting protection for our avian companions. Take a stand against bird strikes with UV Liquid, a responsible choice for bird-friendly architecture.

Truly reduces bird strikes on large glass windows

Truly reduces bird strikes on large glass windows
You can see from the photo that we have an enormous expanse of windows - and we have suffered from bird strikes after we cleaned our windows. This past spring during quarantine, we realized we were having non-lethal strikes once or several times every day, and lethal strikes every other week, terribly sad all around. I was struggling with what to do- I did not want to put glitter stickers or some other tacky option over the nice windows and disrupt the view and aesthetic, but I couldn't keep hearing a bird smash into our window and having to go over to see if it had a broken neck or not. I tried this UV liquid, and tried something that is not on the bottle's instructions. Instead of putting polka dots all over my windows, I instead painted the liquid over the window frames. I hoped that by outlining the glass panes with the bright UV reflection, it would look different enough to them that they wouldn't fly right into the window. It dries clear, you can't tell where I put it- I do have grey paint on my window frames. I waited 3 weeks after painting the window frames to write my review: It Works! I have had no strikes in 21 days. We are still home all day, and my wife has commented on the well it is helping. If you have birds hitting your windows-It is worth a shot. Its not too expensive- it has to be redone every few months so be prepared for that, but it doesn't take long. I have been very happy that I can have my windows and keep the birds safe. Will use from now on.
