WindowAlert decals help prevent window strikes by reflecting ultraviolet light that birds can see. Though the UV reflection is invisible to humans, to the birds, it's like a brilliant glow - like a stop sign!
The decals are approximately 4” across, and are designed for placement on the OUTSIDE of a window. Static cling keeps them mounted to the glass. Easy on, easy off and no sticky residue. We recommend one decal for every 3’ x 3’ section of glass.
We also recommend changing them out every 6 months as the UV coating will degrade over time.
