How does orange light reduce bug presence?
Some bugs, like mosquitos and moths, can't help but move their body towards any light source they can see. This phenomenon is called positive phototaxis. Entomologists still don't have a complete understanding of why this phenomenon exists, but it is clearly observable in nature.
Of course, bugs will only be attracted to light they can see, and there is a useful difference between the spectra of light which are visible to humans compared to bugs. Humans can generally see light which has a wavelength between 380nm (blue) and 740nm (red). Most bugs, conversely, can see light with a wavelength between 300nm and 600nm.
The wavelength of our orange LEDs is 610nm, putting them outside of the spectrum visible to must bugs, but still well inside the boundaries of human vision. As a result, most bugs will not congregate around our orange light because they simply don't know it is there.
