One of the best ways to “spot” invasive cat urine stains is to utilize a black light. Black lights actually emit a long wave of UV radiation. While actually appearing more purple than black, black lights are commonly used to detect anything from forgeries, to improper food handling, and now urine smell and odor.
If the urine is fresh or not entirely dry, the glow it emits will be faint or nonexistent. Even if the stain has had time to try, humidity in the air (e.g., in the bathroom, kitchen, or outdoor areas) or moisture on the stained surface may impair the efficacy of the black light.
The UV Stain Detectives 12 powerful Ultraviolet lights make dried pet urine glow in the dark. You will not have to clean your whole carpet or worse still, replace the entire carpet. UV Stain Detective uses only the very best premium quality UV/LED lights.
You can buy a blacklight flashlight from internet retailers such as Amazon and Ebay. The there is a compound in dried cat pee that will glow a green color under a blacklight. Shine it everywhere, including on walls where cat pee may be sprayed or splattered so thin that you wouldn’t have otherwise noticed it.
To put it simply, black light is a type of ultraviolet light – specifically, ultraviolet A (UVA) light, where it emits ultraviolet radiation in the UVA band. These rays are low-energy and long-wavelength and are the least harmful as far as ultraviolet radiation is concerned.
Semen fluoresces blue between 300-450 nm, in the ultraviolet range. The invisible (to us) UV rays doesn’t interfere with the fluorescence, so forensic experts can see the stains clearly.
Black lights emit a type of ultraviolet radiation called UVA, which is invisible to the human eye. They are often used in industry, nightclubs or amusement parks to make things glow. This glow is the energy emitted by the light being converted into visible light by particles called phosphors.
Beneath a black light, blood turns black, unless sprayed with luminol which gives it a blue-glow. Saliva, semen and urine also glow when hit with a black light. Most biological fluids contain fluorescent molecules to help them glow.
Lastly, finding the source of the glowing material can be difficult, UV lights simply highlight all fluoresce-able substances. We know that urine in general has a mid-to-low intensity glow compared with other fluorescing things, and is a light yellowy-white/straw colour.
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.
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.
Does cat vomit show under black light? While urine will give a strong glow under a UV blacklight, it’s not as simple with vomit. Cat saliva can glow when a UV light is shone onto it, but vomit is usually a mix of saliva and other stomach contents, usually materials that don’t glow.
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.
Petroleum jelly, such as Vaseline, which glows bright blue under a black light. Ripe bananas glow fluorescent blue under a black or ultraviolet lamp.
Black lights, also known as ultraviolet lights (UV), are often used in professional cleaning to help detect if hidden pathogens are present on walls, high-touch areas, ledges, furniture, and scores of other surfaces.
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.
Trimethylaminuria is a disorder in which the body is unable to break down trimethylamine, a chemical compound that has a pungent odor. Trimethylamine has been described as smelling like rotting fish, rotting eggs, garbage, or urine.
Thiamine, riboflavin, niacin, fluids and vitamins shine under black light. Urine, semen and blood contain fluorescent molecules, so they also show up under black light. Interestingly, some cleaners and laundry detergents, scorpions, tonic water and antifreeze and teeth whiteners all also glow under black light.
Higher efficiency - UV LED lights are typically 1.5x - 3.0x more efficient than fluorescent UV blacklights. Longer lifetimes - UV LED lights last for 25,000 hours or more, and do not “burn out” like a fluorescent lamp - their UV light output gradually diminishes over time.
Just as human body secretions are visible under a black light, so are the urine, feces and other body secretions of animals. Black lights are useful for finding the unknown location of pet urine odors and for finding evidence of rats or mice lurking in your home.
A UV (ultraviolet) Light will locate and illuminate body fluid detection for semen or vaginal stains, invisible to naked eye.
Black light experiment shows how quickly a virus like Covid-19 can spread at a restaurant. A viral video from Japan aims to show how easily germs and viruses can spread in restaurants when just one person is infected.
