The Warning Web mimics a sticky spider’s web - a dangerous hazard that birds try hard to avoid. Research suggests that spiders help the birds by weaving a special warning shape at the centre of the web called the stabilimentum, shown here in white. Placed on a window (no adhesive is needed) the Warning Web has the same effect. Use two or more on large windows.
