How to Use a Blacklight Flashlight for Pet Stain Detection

Whether you’re a pet owner or cleaning professional, detecting pet urine stains that have dried or seeped into carpets can be frustrating. Fortunately, a blacklight flashlight (also known as UV flashlight) can help reveal what the naked eye can’t see. This guide explains how blacklight flashlights work, how to use them for pet stain detection, and what to look for when choosing the right one.


What Is a Blacklight Flashlight?

A blacklight flashlight emits ultraviolet (UV) light, typically in the 365–395nm range. This UV light causes certain organic materials—like pet urine, saliva, and even vomit—to fluoresce, making them visible in dark conditions.

? Pet urine glows yellow-green under UV light due to proteins and phosphors in the waste.
