Optical Gel keeps feral pigeons, starlings and mynah birds off all structures without harming them.
It does so by altering their behaviour, not by acting as a physical
barrier. Once applied, birds will completely desert a habitat, even
one they have been using for years.
Optical Gel is applied in low-profile application dishes, only 8mm
high. It has successfully repelled birds from protected "heavy
pressure" sites, and is ideal for sites where the client requires an
invisible solution, or traditional solutions aren't an option.
