CollidEscape for Bats

We should be clear -- there is little research by chiropterologists ("bat scientists") regarding bat strikes with windows.   Anecdotally, while surveying locations for bird strikes, many ornithologists and their volunteers have reported bat bodies in their studies. Unfortunately, few surveys have included bat data in their reports.  


The causes of the bat deaths are vigorously debated; with acoustical echolocation for prey, there is the supposition that the smooth and highly acoustically reflective surface is disorientating to young bats.  Some chiropterologists have also postulated that glass "sounds" like water, where bats will often skim insect pray off a surface they anticipate to be pliable and forgiving of impact.

Regardless, disruption of the surface with a textured, patterned solution like CollidEscape has been observed in independently surveyed locations to not only reduce bird body accumulation but the accumulation of bat bodies as well.

If your location is experiencing a collection of bats below your windows, we encourage you to give CollidEscape a chance; it will reduce or even with some solutions, completely eliminate bird strikes, and may also help our mammalian friends as well!

How Glass Fronts Deceive Bats
  by Peter Stilz


Bats often navigate rapidly through complex environments by using echolocation, a sensory modality that is profoundly different from human vision (1). Building a sufficient three-dimensional perception of their environment on a lower-dimensional sensory input than human vision, they perform a complex task. They are thus forced to apply a high degree of processing and interpretation to the sensory input, making them prone to sensory deceptions. -report that vertical mirrorlike reflecting surfaces, which bats perceive as open flyways, can act as sensory traps.
