What is a Pet​ Urine Detector?

Using a urine detector may make you feel a little bit like Sherlock Holmes. After all, if there was ever a case worth solving it, it's that relentless, lingering urine smell. But UV light will expose any stains and are simple to use. Simply turn off the lights and go on the hunt. Some places to look include: areas by indoor plants, pet beds, under their crate, by draped blankets or long curtains, or by doors that lead outside.

Frequently Asked Questions
Why does urine glow under a backlight?

Urine contains phosphorus, which glows yellowish green in the presence of oxygen. When you use a UV light, it imparts additional energy that makes the change in color easier to see.

Does the smell of dog urine go away?

Dog urine odor will not go away on its own. That is why it is important to first detect the areas where urine has dried up and then treat and clean the area.

How can I make my house not smell like dog urine?

Once you detect the urine spots, you will need to clean the area. There are many cleaning products available as well as at home solutions using mixtures of peroxide, baking soda and dish soap, that can help.
