STEP 01
Darken the Room
Turn off the lights and close the blinds. UV fluorescence is easiest to see in near-total darkness — daylight and room light wash it out.

DESIGNED FOR FINDING PET URINE
THREE SIMPLE STEPS
TO FIND THE SPOT.
No lab equipment needed. Just darken the room, sweep the light, and mark what glows.
STEP 02
Sweep Low & Slow
Hold the flashlight close to carpets, mattresses, and baseboards. Move it slowly — old stains often hide near furniture legs and room corners.
STEP 03
Mark & Clean
Stains typically glow yellow-green under UV. Mark the spot (a bit of tape or a sticky note works well) and treat it while it's still visible.

Answers based on what buyers actually want to know before searching for pet urine with a 365nm UV flashlight.
You don't need pitch darkness, but the darker the room, the more the stains stand out. For best results, turn off the lights, close the curtains, or search after sunset — even a lamp or daylight from a window will wash out fainter stains and make them harder to see.
It's actually the opposite of what most people expect: UV light detects dried urine, not fresh, wet accidents. The crystals left behind as urine dries are what glow under the 365nm beam, so this flashlight is at its best on old stains you can't see or smell your way to — including ones from months ago.
Keep it within about 12–24 inches of the surface and move slowly — waving it around from standing height will make you miss smaller or fainter spots. For carpets and rugs, get down on one knee and sweep low, section by section, rather than scanning the whole room from above.
Yes — UV light reveals lots of things, not just urine, including some cleaning products, lint, certain fabrics, and even some food or drink residue. Genuine pet urine typically glows a pale, straw-yellow color. Vacuuming the area first removes fuzz and debris that can otherwise cause false positives.
It works on both, and carpets and rugs are actually where it's most useful — urine soaks into the fibers and padding, and a 365nm beam will reveal it even when the surface looks completely clean. It also works well on mattresses, upholstery, baseboards, and hardwood.
It charges over USB-C, so there's no hunting for the right cable, and a full charge is enough for several search sessions of everyday use. We'd rather it last through your worst pet-mess emergency than blink out mid-search — that's why we built in a battery this size.
Used normally — pointed at floors, furniture, and walls to search for stains — it's safe for household use. As with any UV light, avoid shining it directly into your eyes or your pet's eyes for extended periods, and it's not intended for use on skin.
Yes. The 365nm wavelength picks up the dried crystals in urine regardless of which pet it came from, so it works the same whether you're tracking down a cat's litter-box miss or a dog's accident by the door.
Yes — as a bonus, the same 365nm UV beam reveals the security markings built into most banknotes and ID cards, so it doubles as a quick authenticity check. It's a handy extra, but the flashlight is built first and foremost for finding what your pets leave behind.
