Award: BEST FOR CAMPING
WHY WE LIKE IT: TaoTronics has the best UV flashlight for scorpions as it is ultra-compact, durable, and powerful. Because it’s small and pocket-friendly, you can always keep it close to you when you’re camping to protect yourself from critters.
TaoTronic’s UV flashlight has only 12 LEDs. However, unlike our first two picks, these lights have longer lifespans, lasting up to 15 years. You also get the three AAA batteries needed to power this flashlight for free.

Ultraviolet lights go from 10nm-400nm. However, it’s not as effective on cat urine. On the bright side, it can be used for other purposes such as authenticating documents or identifying unwanted whitening components in cosmetics. It’s also great for spotting scorpions when you’re camping because of its ultra-compact design. You can take it everywhere with you as it is small enough to fit in your pocket. Have this handy while you are in the best sleeping bags.
