A black light is a type of light bulb that emits mostly ultraviolet radiation. Although most bulbs also give off a faint violet glow, the majority of the light is outside the visible range. This energetic radiation excites molecules, often producing fluorescence or phosphorescence. A visible photon is released when a molecule loses the absorbed energy, making the substance appear to glow in the dark.

    I’ve been having a mite problem in my home. I bought a UV light and suspect they glow orange under it but would like to confirm. Some look like strings but I read they shed their exoskeleton and am thinking maybe that’s what gives that appearance????

      Many arthropods, such as mites, fluoresce or “glow” under a black light. It’s sometimes due to a chemical that hardens their exoskeletons when they molt. But, you can’t be sure if your mites glow until you catch some and check. Also, some arthropods see UV light. Whether they are attracted, repelled, or indifferent to it depends on the species, but the mites may hide from the light.
