Designed to work with or without decals, this UV-reflective liquid helps create a dotted barrier that birds perceive as a warning. The result is a calmer window area around homes and buildings, especially where glass catches the sun or bright reflections.\u003c\/p\u003e\n\u003ch3\u003eHow it works\u003c\/h3\u003e\n\u003cp\u003eApply the marker dots on exterior glass using our bingo marker. The dots dry to a nearly invisible, clear finish that blends with the glass while enhancing visibility for birds. For optimal coverage, place dots about 4 inches apart horizontally and 2 inches apart vertically, forming a grid that reduces the chance of a strike.\u003c\/p\u003e\n\u003cp\u003eUse in conjunction with WindowAlert decals for a complete barrier, or rely on UV Liquid on its own for flexibility. The ultraviolet reflectivity is most effective in daylight and can be reapplied as needed to maintain protection across seasons.\u003c\/p\u003e\n\u003ch3\u003eWhat makes UV Liquid a practical choice\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eComplements window decals by filling gaps and extending coverage\u003c\/li\u003e\n  \u003cli\u003eEasy exterior application that dries clear and is simple to remove with standard cleaners\u003c\/li\u003e\n  \u003cli\u003eEach 1-ounce bottle is crafted in the USA, aligning with quality and environmental goals\u003c\/li\u003e\n  \u003cli\u003eDurable enough to provide months of protection, with reapplication recommended every 4 months or when reflectivity fades\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eReal-life uses and considerations\u003c\/h3\u003e\n\u003cp\u003eIdeal for homes, offices, and storefronts with large glass facades or glass doors. The dots are small enough to be discreet in daylight, yet noticeable enough to alert birds when placed according to spacing guidelines. The product can be used alone or as a supplement to existing deterrent decals, offering a flexible solution for different window configurations.\u003c\/p\u003e\n\u003cp\u003eApplication is straightforward: ensure an exterior glass surface is free of overlays, dirt, and cleaners; apply with the bingo marker to form dime-sized dots; allow to dry.

The feature’s 12-month shelf life supports long-term planning for building management and maintenance cycles.\u003c\/p\u003e\n\u003ch3\u003eWhat you gain\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eReduced risk of window collisions for wild birds in a humane, non-chemical format\u003c\/li\u003e\n  \u003cli\u003eClear drying dots that do not obstruct overall aesthetics of glass surfaces\u003c\/li\u003e\n  \u003cli\u003eVersatility to use with or without decals, depending on project needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eProduced with care in Bend, Oregon, WindowAlert remains a trusted option for bird-friendly architecture.
