InvisiDye UV Marker - 1 Pint

Geese and other birds can see ultraviolet (UV) light waves (200-400nm) which allows them to see a portion of the light spectrum that is invisible to the human eye.

InvisiDye is a water-based ultraviolet dye that can be used with other products as a UV- marker.

When you use InvisiDye inside of the mixture with Flock Free Tank Mix or any other bird repellent, it creates a visual marker visible for birds but not for humans. The birds see the treated areas and connect them with the unpleasant feeling they experience when they touch Tank Mix or inhale its vapors.

At the same time, InvisiDye looked transparent for humans' eyes and it doesn't create unnecessary colors on treated surfaces.

InvisiDye increases the effectiveness of Tank Mix and other bird deterrents and helps you to reach the desired results faster.
