Methods to Eradicate Rat Urine Smell

Get Rid of Rat Urine Smell

1. Natural Cleaning Products

Getting rid of rat urine smell can be challenging, but using natural cleaning solutions can be effective in neutralizing the odor. Here are some methods you can use:

a. White Vinegar : Mix equal parts of white vinegar and water (generally 1:1 ratio) in a spray bottle. Spray the affected area generously, and let it sit for a few minutes. After that, use a clean cloth or paper towel to wipe the area clean. The vinegar will help neutralize the odor, and disinfect the surface.

b. Baking Soda: Sprinkle baking soda over the affected area, and let it sit for a few hours or overnight. Baking soda is a natural odor absorber and will help to neutralize the smell. Afterward, vacuum or sweep up the baking soda and clean the area with a damp cloth.

c. Hydrogen Peroxide (H2O2): Form a solution mixture containing one part of hydrogen peroxide, and two parts water in a spray bottle. Spray the affected area, and let it sit for a few minutes. Then, use a clean cloth or paper towel to wipe the area clean. Hydrogen peroxide is a powerful disinfectant, and can help to break down the odor-causing compounds in rat urine.

d. Lemon Juice: Mix equal parts of lemon juice and water in a spray bottle. Spray the affected area, and let it sit for a few minutes. Then, use a clean cloth or paper towel to wipe the area clean. The citric acid in lemon juice can help to neutralize the odor and leave a fresh scent behind.

e. Essential Oils: Some essential oils, such as tea tree, eucalyptus, and lavender, have natural disinfectant and odor-neutralizing properties. Add a few drops of your chosen essential oil to a spray bottle filled with water, and spray the affected area. Let it sit for a few minutes before wiping it clean with a cloth or paper towel.

2. Ready-Made Cleaning Products

There are several commercial cleaning products available that are specifically designed to eliminate odors, including rat urine smell. Some popular options include enzyme-based cleaners, such as Nature’s Miracle or Simple Solution, which break down the odor-causing compounds in urine. Always follow the manufacturer’s instructions for use and test a small, inconspicuous area before applying the product to a larger area.

3. Deodorizing Techniques

a. Air Purifiers: Air purifiers can help to remove airborne particles and odors from the air, including those caused by rat urine. Look for air purifiers with HEPA (High Efficiency Particulate Air) filters and activated carbon filters, as these are most effective at trapping and neutralizing odors.

b. Activated Charcoal: Activated charcoal is a natural odor absorber, and can be used to help eliminate rat urine smell. Place activated charcoal bags or sachets near the affected area, and replace them as needed. This method is most effective when used in conjunction with other cleaning and deodorizing techniques.

4. Deep Cleaning Methods

a. Steam Cleaning: Steam cleaning can be an effective way to deep clean surfaces and remove lingering odors caused by rat urine. Rent or purchase a steam cleaner and follow the manufacturer’s instructions for use. Steam cleaning can be particularly useful for cleaning carpets, upholstery, and other porous materials that may have absorbed the urine smell.

b. Replacing Contaminated Materials

In some cases, the rat urine smell may have penetrated materials to such an extent that cleaning alone is not enough to eliminate the odor. In these situations, it may be necessary to replace contaminated materials, such as insulation, drywall, or flooring. This can be a more costly and time-consuming option, but it may be the only way to completely remove the smell and ensure a clean, odor-free environment.

Tips for Maintaining a Rat-Free Environment

Along with odor removal, it is mandatory to maintain a rat-free environment. Following the below-mentioned tips can pave your way to prevent rat infestations, and protect your property in the future. 

  • Seal entry points: Inspect your home or building for any gaps, cracks, or holes that rats could use to enter. Seal these openings with materials like steel wool, caulk, or metal sheeting to prevent rats from gaining access.
  • Keep your space clean and clutter-free: Rats are attracted to areas with abundant food sources and hiding places. Regularly clean your living spaces, store food in sealed containers, and eliminate clutter to discourage rats from nesting.
  • Proper waste disposal: Ensure that garbage is stored in tightly sealed containers and removed regularly. Keep outdoor trash cans away from your home and use lids that securely fasten to prevent rats from accessing the contents.
  • Trim vegetation and maintain your yard: Overgrown vegetation and piles of debris can provide shelter for rats. Keep your yard well-maintained by trimming bushes, cutting grass, and removing any debris or woodpiles.
  • Eliminate water sources: Rats need water to survive, so eliminating sources of standing water can help discourage them from settling in your area. Fix any leaks, remove water containers, and ensure proper drainage around your property.
  • Regularly inspect your property: Regular inspections can help you identify signs of rat activity early on, allowing you to take action before an infestation becomes severe. Look for signs such as droppings, gnaw marks, or nesting materials.


What Does Rat Urine Smell Like?

Rat urine has a strong, pungent odor that is often described as musty or ammonia-like. The smell can be quite unpleasant and is usually more noticeable in confined spaces or areas with poor ventilation.

Can The Smell Of Rat Urine Be Harmful?

Yes, the smell of rat urine can be harmful to humans. Prolonged exposure to the odor can cause respiratory issues, headaches, and allergic reactions. Additionally, rat urine can contain harmful bacteria and viruses, which can lead to serious health problems if inhaled or ingested.

How Long Does Rat Urine Smell Last?

The smell of rat urine can last for several weeks or even months, depending on factors such as the size of the infestation, the amount of urine present, and the level of ventilation in the affected area. Thorough cleaning and disinfection of the area can help to eliminate the odor more quickly.

Will Bleach Kill Rat Urine Smell?

Bleach can help to neutralize the smell of rat urine, but it may not be the most effective solution. A better option is to use an enzyme-based cleaner specifically designed to break down the proteins in urine, which will help to eliminate the odor more effectively. Be sure to follow the manufacturer’s instructions for use and always wear protective gloves when handling cleaning products.

Does Rat Urine Smell Go Away?

Yes, rat urine smell will eventually go away once the source of the odor has been removed and the area has been thoroughly cleaned and disinfected. However, it may take some time for the smell to dissipate completely, especially in areas with poor ventilation or where the urine has soaked into porous materials. Using an enzyme-based cleaner and ensuring proper ventilation can help to speed up the process.


Effectively eliminating the unpleasant odor of rat urine and maintaining a fresh living environment requires employing various strategies. Natural cleaning solutions like white vinegar, baking soda, H2O2, lemon juice, and essential oils offer eco-friendly ways to neutralize the odor and disinfect surfaces.

In addition, some ready-made cleaning products can also break down the odor-causing compounds. Moreover, deodorizing techniques like air purifiers with HEPA filters and activated charcoal eliminate the problem.
