If you have scorpions around get a 365nm UV light and a visible light filter. I was shocked by how far away I could see them.

    I have tried using UV lights in the past but I only used a 390nm UV with no visible light filter. With no visible light filter blue light is emitted and washes out stuff that is fluorescent.
