how to get rid of mouse urine smell

Many ugly situations may cause embarrassment when you have visitors in your house, but none of them beats a blanket of pungent smell hovering around your lounge! It becomes worse when the smell has an irritating nature that keeps your visitors sneezing. This is the scenario you’re likely to encounter if you fail to tame the mice early enough. They infest your house and spread their urine whenever they pass. As a result, your house produces a detestable odor almost rendering it inhabitable. Is there a solution to the problem? Well, you shouldn’t worry about how to rid your house off the smell. This article provides crucial, well-articulated tips to help you in eliminating the repelling mouse smell!


You need to be on the lookout for a funny smell originating from your house or even your car. The mouse odor primarily comes from the urine. You’ll, therefore, detect a pungent ammonia-like smell. If you notice the unusual smell, you need to investigate the cause.

The process can be completed successfully by answering the following vital questions exhaustively:

  • Do you keep pets, such as dogs and cats, in your house? If your answer is affirmative, then the odor is either a result of the pets or mice. You’ll need to look out for more signs that may include nests and fecal matter. In case there are no other signs of mice infestation, it’s highly possible that what you’re experiencing isn’t mouse odor.
  • Which is the primary source of the smell? You need to investigate the origin of the smell to determine whether you’re suffering mice infestation or not. Mouse odor’s concentration increases as you move towards their hiding areas including enclosed kitchen cabinets and dark corners of your house.
  • Have you used mouse traps recently? If yes, have you eliminated all the mice successfully? The pungent smell can originate from three sources including urine, droppings, or a dead mouse. If you recently used best mouse poison products or the best mouse traps to kill the mice, it’s possible that the smell you’re experiencing is as a result of a decaying mouse! If you’re sure that you disposed of all the dead mice, then it’s time to clean all the surfaces to eliminate mouse urine and droppings.

While it is hard to differentiate between the mouse odors and smell originating from other sources, some obvious signs confirm the presence of mice in your house.

You should watch out for the following two indicators:

  1. A nose-burning sensation especially when you approach regions of higher odor concentration. While the ammonia concentration on the mouse urine, between 0.5% and 1.5%, is considered harmless, a buildup of the waste without cleaning results in a high concentration that has the potential to cause a burning sensation on the skin. This scenario mostly affects the nostrils due to the skin sensitivity and strong sense of smell in the nose.
  2. Look for stains. Mouse urine has high calcium levels which may leave white deposits when dry. Such coloration is a clear indication that the strong smell you’ve recently experienced is indeed a mouse smell.

What does mouse urine smell like?

Mouse Pee AreaJust like all the other animals, mice urinate frequently. The primary components of the rodent’s urine are water and urea. The longer it stays unwashed, the stronger the ammonia-like smell becomes. The increased concentration of the smell results from a breakdown of the nitrogen-rich urea into ammonia which has a pungent smell.

What do mouse droppings smell like?

Mouse dropping does not present a striking odor. It has a faint unpleasant odor when flesh but the smell disappears once the poop dries. After approximately one week, the droppings may disintegrate which can lead to increased poop-dust inhalation. If an individual is allergic to dust, a problem may arise with frequent exposure to the dust. As such, you should ensure that you clean up immediately you spot them.
