Your UV light will work best with a solid colored surface. Look for a pale yellow glow. If you are seeing different color glows on your surface, you may be confused as to which is pet urine. Urine fluoresces as a pale yellow color.
Vitamin A and the B vitamins thiamine, niacin, and riboflavin are strongly fluorescent. Try crushing a vitamin B-12 tablet and dissolving it in vinegar. The solution will glow bright yellow under a black light.
In a nutshell, there isn’t quite a difference, but a misunderstanding of the terms. Black light is nothing but UVA light, while UV light is basically composed out of UVA, UVB and UVC. So in other words, black light is UV light(450-100nm), covering the 400-320nm spectrum.
Some of the spills a person might find with a black light include:- Biological stains: saliva, semen, urine and blood.
Cat urine contains uric acid, which can last in carpets, fabrics and wood for years! Although baking soda, vinegar, soap, and hydrogen peroxide may neutralize the odors temporarily, a humid day can cause the uric acid to recrystallize, and the infamous “cat odor” will return.
Petroleum jelly, such as Vaseline, which glows bright blue under a black light. Ripe bananas glow fluorescent blue under a black or ultraviolet lamp.
Whereas urine that’s sprayed typically shows up on vertical surfaces (e.g., furniture, walls, etc.). If you’re able to catch your cat spraying/marking in real-time, you’ll most likely see them standing with their back to their vertical “target” and holding their tail held straight up.
Cat spray looks and smells like urine, to a point. A well-hydrated kitty produces light yellow urine with its typical acidic odor. But because of pheromones in cat spray, it’s often darker yellow and smells particularly more pungent.
Overexposure to Ammonia
Breathing in cat urine can actually make you sick. Cat pee is full of ammonia, a toxic gas that can cause headaches, trigger asthma attacks, and even result in serious respiratory illnesses such as pneumonia.
A couple components contribute to feline urine odor. First, cat urine tends to be more concentrated than human urine — and even dog urine. Like other species’ urine, cat urine contains urea, ammonia, uric acid and creatinine. These are natural waste products of protein breakdown.
Colors That Glow Under Black Light- Whites. White paper, paint and fabrics are treated with fluorescent additives to make them brighter.
Yellows. Bright yellows paints and fabrics will glow, due to the additives to make them bright.
The ultra-violet rays used by black lights use the same wavelength as biological waste such as urine. When using a backlight to find cat urine spots , turn out the lights and shine the black light over all areas of the carpet. Most urine stains will produce a noticeable glow.
That distinctive odor can be an indication of a mold problem. Certain types of mold have a smell similar to cat urine, including dangerous toxic black mold, which should be remediated by a professional. Another source of cat urine odor is ornamental boxwood, a common landscaping shrub.
Here are a few things you might have in your house with that glow under UV: Tonic water – the quinine in tonic water glows blue. Honey – the aromatic molecules in honey can glow green. Turmeric root – the curcumin in turmeric glows yellow.
They’re a familiar sight to most, but America’s only marsupial has a secret: beneath their furry exterior, opossums glow hot pink under the right light – not headlights, but ultraviolet light.
Reddish orange manganese glass is sometimes called “persimmon glass.” Manganese Dioxide (MnO2) was also used to decolorize glass containing iron impurities, or to stabilize the color of glass so it wouldn’t shift over time. Glass that contains manganese glows green, red, orange, or peach under black light.
They employ “Wood’s Glass” which is nickel-oxide-doped glass. Or in layman terms; an exterior coating that blocks most visible light and allows ultraviolet through. Black Light bulbs are typically used for bug zappers.Blacklight.

Exposure to UVA from black lights is well below the recognised safe limits and is not hazardous to people using them, working in their vicinity or who have them in their home. Exposure from black lights would be much lower than your exposure to UVA outdoors.
Semen won’t give off light like a glow-in-the-dark sticker, but it does fluoresce. In other words, it absorbs ultraviolet light and re-emits that energy as visible light.
