You walk into a room and immediately are caught off guard by an unpleasant smell, but you aren't sure where it is coming from. You think it might be pet urine, but you have never seen your cat spray, so you want to make sure that is it before you spend a lot of money on expensive pet urine remover. Purchasing a stain detecting black light can help you determine if you have pet urine stains in your home, as well as other stains from bodily fluids and even mould.

Turn off all other lights in the room that you want to detect stains in. You should also close any blinds and curtains, to make the room as dark as possible.
Turn on your black light and begin to work your way around the room, black light in hand. Larger bodily fluid stains will show up from a distance; smaller stains, however, will begin to appear as you get closer to them with the black light. When you see a spot that appears to be glowing a sort of neon yellow or green, then you have found a stain.
Pay special attention to areas behind furniture and in corners if you are looking for pet urine stains, since these are areas that pets tend to gravitate towards when looking for a place to spray.
As you test any area with a black light, keep in mind that the black light can detect semen, blood and urine. It can't, however, tell you which stain is which.
Use the black light to detect mould stains, especially in areas of your house where they are most likely to occur, such as bathrooms and damp basements.
Detecting Stains With a Black Light
Tips and warnings
- You want a professional grade black light for thorough stain detection, not the type of black light that you would pick up at a party supply store. There are many places online where you can pick up such a black light, and many pet stores carry stronger black lights as well. Party grade black lights will pick up some stains, but may not pick up all stains.
