Raccoons may be cute from a distance, but if they’ve made themselves comfortable in your attic, garage, or yard, they can leave behind an unpleasant reminder: their urine. The pungent smell of raccoon urine can be quite overwhelming and difficult to get rid of, especially if it soaks into porous surfaces like wood, insulation, or soil.
If you’ve noticed that lingering odor, don’t worry—there are several effective ways to remove raccoon urine smell and get your space back to smelling fresh and clean.
Let’s keep going to find them out!
Why Does Raccoon Urine Smell So Bad?
Raccoon urine has a particularly strong and unpleasant odor because it contains high levels of ammonia and waste proteins.
Over time, these substances break down and release volatile compounds that make the smell worse. If the urine soaks into porous surfaces like wood, insulation, or soil, it can continue to smell for weeks or even months if not properly treated.
Raccoons tend to return to the same spots to mark their territory, meaning the urine smell can build up over time if the animals aren’t kept out. This is why it’s important to not only clean the area but also take steps to prevent raccoons from returning.
Step-by-Step Guide to Remove Raccoon Urine Smell
To remove raccoon urine smell, clean the affected area with an enzyme-based cleaner that breaks down the urine molecules, scrub surfaces thoroughly, and ventilate the space.
Prevent future odors by sealing entry points and using repellents to keep raccoons away. Follow these steps to effectively eliminate the odor from your home or outdoor areas.
Step 1: Identify the Source of the Smell
Before you start cleaning, it’s important to locate the exact area where the raccoon urine is concentrated. This could be in your attic, garage, or yard—wherever raccoons have gained access.
- Look for signs of raccoon activity: Check for droppings, tracks, or nesting materials that might indicate where the raccoons have been staying. Common entry points include open windows, roof vents, or holes in the attic or garage.
- Use a blacklight: A UV blacklight can help you identify the areas where urine has soaked into surfaces, as the urine will fluoresce under the light.
Identifying the precise locations will make the cleaning process more effective and prevent you from missing any hidden spots.
Step 2: Clean the Affected Area
Once you’ve identified where the raccoon urine is concentrated, it’s time to clean the area thoroughly. Depending on the surface—whether it’s wood, insulation, or soil—the cleaning method will vary slightly.
For hard surfaces (wood, concrete, etc.):
- Use an enzyme-based cleaner: Enzyme-based cleaners are highly effective at breaking down urine molecules and eliminating odors. Apply the cleaner generously to the affected area and let it sit for the recommended time (usually 10–15 minutes). These products are specifically designed to digest the ammonia and proteins in urine, neutralizing the smell at its source.
- Scrub the surface: After letting the cleaner sit, scrub the area thoroughly with a stiff brush or sponge. Pay extra attention to cracks or crevices where the urine may have seeped in.
- Rinse and repeat: Rinse the area with clean water and allow it to dry completely. If the odor persists, you may need to repeat the cleaning process a few times.
For soft surfaces (carpets, fabrics, insulation):
- Remove contaminated materials: If possible, remove any contaminated insulation or fabric that has been soaked with urine. These materials are often difficult to clean thoroughly and can continue to hold the smell even after treatment.
- Clean with enzyme cleaner: For fabrics or carpets that cannot be removed, apply an enzyme cleaner and follow the same process as with hard surfaces. Use a wet/dry vacuum to remove excess moisture after scrubbing.
For soil or outdoor areas:
- Soak with a water and vinegar solution: For urine spots on soil or outdoor areas, soak the area with a mixture of water and white vinegar. The vinegar helps neutralize the ammonia in the urine. Let the mixture sit for about 30 minutes.
- Rinse thoroughly: After soaking, thoroughly rinse the area with a hose to flush out the urine and vinegar mixture. You can repeat this process as needed until the smell dissipates.

Step 3: Deodorize and Ventilate the Area
Once the urine has been cleaned, it’s essential to deodorize and ventilate the area to remove any lingering odors.
- Use odor-neutralizing sprays: After cleaning, use an odor-neutralizing spray or product designed for pet odors. These sprays can help eliminate any remaining smells and keep the area fresh. Look for products that target ammonia and urine odors specifically.
- Open windows and doors: If you’re dealing with an indoor space like an attic or garage, make sure to open all windows and doors to ventilate the area. Fresh air circulation helps speed up the drying process and removes lingering odors.
- Use fans: Set up fans to blow air out of the area. This will help push stale air and odors out of the space more quickly.
Step 4: Prevent Future Issues
Once you’ve successfully removed the smell of raccoon urine, it’s important to take steps to prevent the problem from recurring. Here’s how you can keep raccoons from coming back:
- Seal entry points: Inspect your home for any potential entry points where raccoons could get in, such as open vents, cracks, or holes in the roof or siding. Repair any damage and use raccoon-proof materials like steel mesh to block access.
- Install deterrents: Motion-activated lights, sprinklers, or noise devices can help scare raccoons away from your property. Raccoons are nocturnal, so bright lights or unexpected sounds can discourage them from returning.
- Use raccoon repellents: Natural repellents, such as predator urine (like coyote or fox urine) or store-bought raccoon repellents, can be used around the perimeter of your home or yard to deter raccoons from returning.
- Keep food sources away: Make sure any food sources—such as pet food, bird feeders, or trash cans—are secured and inaccessible to raccoons. These critters are notorious for raiding garbage bins, so using raccoon-proof trash cans with locking lids can help keep them away.
How to Handle Lingering Odors
If you’ve followed the cleaning steps and still notice lingering odors, it’s possible that the urine has deeply penetrated porous materials, or that some areas were missed. Here are a few additional steps you can take:
- Consider professional cleaning: If the smell persists after multiple attempts, it may be worth calling a professional cleaning service that specializes in odor removal, especially if the affected area is large or hard to access.
- Use activated charcoal: Activated charcoal is excellent at absorbing odors. Place bowls of activated charcoal around the affected area to help neutralize any remaining smells.
- Ozone generators: Ozone generators can be effective at removing stubborn odors from indoor spaces. These devices produce ozone, which can neutralize odors in the air. However, ozone generators should only be used in unoccupied areas, as high levels of ozone can be harmful to humans and pets.
End Note
Raccoon urine smell can be tough to deal with, but with the right approach, you can effectively remove the odor and restore your home or yard to its fresh state. Start by identifying the affected areas, using enzyme-based cleaners to break down the urine molecules, and then deodorize and ventilate the space. Finally, take steps to seal entry points and keep raccoons away from your property.
By following these steps, you can tackle even the toughest raccoon urine odors and ensure they don’t come back. With a little effort and the right tools, your home or outdoor space will smell fresh and clean again.
