If you don't feel like messing with a full-sized black light, they make UV flashlights for pet urine detection / scorpion hunting that are powerful and directed to get that extra oomph when you charge something glow in the dark. 

Protip: those are also great for finding hornworm caterpillars in your garden.

Scorpions and Caterpillars? I get the finding bodily fluids thing, but how does it help detect arthropods? Bodily fluids in a different way or is it different for arthropods?

They glow under UV light. Really nothing more to it than that. 

I can't personally attest to scorpion hunting, but a green hornworm caterpillar that's basically invisible against a tomato plant under sunlight is much easier to find at night under UV.

Oh neat, I might have to look into why that is sometime.

They have phosphors in their skin that emit light when exposed to ultraviolet (UV) radiation.
