So, anything made out of it will glow in UV light including bed bugs, their eggs, nests, feces, and discarded old shells.

 

1. Why Bed Bugs Glow in UV Light?

It is true that regular light is similar to UV light. However, the major difference is where they are on the spectrum of light.

Visible light can be defined as the light which we can see with our eyes. Various wavelength of light appear in various colors ranging from green, yellow, red, and blue. The light’s energy will depend on the level of wavelength. Higher the wavelength, the more will be the energy of the light.
