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.
You can use a black light to detect body fluids. It’s actually a good way to look for pet urine or make sure a bathroom or hotel room is really clean. Cat urine, in particular, glows very brightly under ultraviolet light. Urine glows under a black light primarily because it contains the element phosphorus.
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.
Instead, try using a UV light, also known as a black light. If you shine the light in a dark room, cat urine will glow yellow or green, making it easy to see exactly where you need to clean.
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.
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.
The lights cause materials such as bacteria, urine, seminal fluids and blood, to “fluoresce,” so that the naked eye can detect them. Typically, UV lights are used to test surfaces especially when there is a disease outbreak or any sudden increase in occurrences of a specific disease at a particular time or place.
Lots of things glow under a black light (white, green, blue, even red) but look for the pale yellow color that a urine stain creates. Pet urine stains look different depending on whether the dog squatted or leg-lifted. Stains can look like a pooled puddle, drips, or splatters on the floor, furniture, or walls.
Besides being the main culprit behind cat urine’s noxious smell, exposure to ammonia can leave your kitty with irritated eyes, nose, throat, lungs and skin an even trigger asthma or upper respiratory infections, which can be dangerous and costly with vet visits.
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 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.
A very small amount of natural sapphires (sapphires can be any color except red) can glow under UV light. Natural colorless, pink, or occasionally blue sapphires with low iron content (iron is fluorescent quencher) can glow red, pink, or orange in long-wavelength UV light.
As mentioned above, fluorescent tubes use the same technology to create ultraviolet radiation as the UVC bulbs, but they use different phosphors to convert that UV radiation to visible light. The phosphors absorb the UV, making them safe, and emit visible light.
Plastic stars, toys, urine, and tonic water are some things that glow under black light. A black light is a type of light bulb that emits mostly ultraviolet radiation. Although most bulbs also give off a faint violet glow, the majority of the light is outside the visible range.
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.
Cutibacterium acnes, a bacterium involved in acne causation, exhibits an orange glow under a Wood’s lamp.
The latest black light flashlights are useful for identifying counterfeit money, turning up pests, rodents or mites, and also detecting soiled bedding, furniture or rugs.
Blue LEDs are also used by police and crime scene investigators because it will make blood and bodily fluids visible that are usually invisible to the naked eye. Blue light is the only light that can cut through fog, which is why it is widely used for fog headlights. A $50 bill under Ultraviolet light.
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.
