The odor is intensified by other smells such as garbage or sewage, making them even harder to handle! Dead rat removal should always be handled by professionals because there are many health risks involved with handling these animals yourself, including diseases like histoplasmosis and tetanus just from being scratched on an infected animal.

10 Ways on How to Get Rid of Dead Rat Smell in Wall

1. Use a Dehumidifier

A dehumidifier is essential for getting rid of the dead rat smell in the wall because the trapped moisture will only help spread the bad odor. Remember that thick foam insulation can hold back even more moisture than usual. A dehumidifier with a hygrometer (to measure humidity) is best so you know when it’s time to increase the frequency of your dehumidifier’s cleaning.

2. Clean the Area with a Vinegar Solution

Mix one part vinegar to three parts water in a spray bottle, then clean the entire area where the smell is coming from. Make sure to get into all the nooks and crannies. The vinegar will help to kill the bacteria that is causing the smell. If you still have a lingering smell, there may be more bacteria lurking around. You can try a vinegar soak. Mix one part vinegar to one part water in a bucket and soak the entire area for 30 minutes. This will help to kill any remaining bacteria.

3. Use Baking Soda

Baking soda can also be used to help get rid of the dead rat smell in your wall. It works by neutralizing the bad odor. Sprinkle it over the areas where you smell the rats, and then let it sit for about 30 minutes before you vacuum it up. You can also use baking soda on your floors and other surfaces to help eliminate the smell. Another way that you can get rid of the dead rat smell in your wall is by using vinegar. Vinegar is a natural deodorizer, so it will work to neutralize the bad odor.

You can also mix baking soda with water, then put the paste into a spray bottle and clean the area where the smell is coming from; be sure to wear protective gloves when using this method. Don’t mix it with vinegar, though, because there are conflicting reports on whether or not this will create harmful fumes. Of course, if you’re dealing with a serious dog odor problem, it might be time to call in a professional. An experienced dog trainer can work with you to ensure your furry friend is well-behaved and housebroken.

4. Try Some Natural Odor Removal Disks

Natural Odor Removal Disks

There are special disks that work to control odors by removing them from the air. You can put one in an affected room, but make sure you do it at least 24 hours after you’ve used baking soda or vinegar to remove the smell because those are masking odors, and these disks are real odor removers. The disks work through a natural process called photocatalytic oxidation. They need sunlight to work, but don’t worry, they can still produce a chemical reaction even on cloudy days and at night.

5. Soak Some Coffee Grounds in Hot Water

If you have some coffee grounds on hand, boil some water, soak some of them in it for 30 minutes, and then remove them from the solution. Next, put this liquid into a sprayer and spray the entire area where the smell is coming from. The coffee will give off an unpleasant odor that should help mask the natural bad odor of a rat infestation.

6. Put Some Fabric Softener Sheets in Your Home

Fabric softener sheets can also help you get rid of dead rat smells by absorbing the bad odor. Place them in all the rooms where you smell the rats, but replace them every few days because they will start to lose their effectiveness over time. Baking soda is a good option for removing bad smells. You can sprinkle it on the floor and in all the areas where you think the rats have been, leave it there for a few hours or overnight and then vacuum it up.

7. Use an Air Purifier

An air purifier is a great way to get rid of any bad smells in your home, including the smell of dead rats. Be sure to put this in the room where you smell them at because it can’t do its job if you don’t.

8. Use Activated Charcoal Bags

If your wall is too far gone for any of these other methods to work, then you’ll have to use activated charcoal bags (also known as deodorizer bags). They’re extremely effective at removing odors, so they can also remove the smell of dead rats. Place these in your wall for several days or until the smell is gone, whichever comes first.

9. Use a Keg

Use a Keg to Remove the Smell

If you have access to a keg, then put it into the affected room and wait for about 24 hours before moving it somewhere else in your house. Take care not to move it too much so you don’t disturb the dead rats. The carbon dioxide will help to absorb the bad odor.

10. Scrape and Bleach

If you can’t wait for the keg and your wall needs to be repaired as soon as possible, then use a scraper to remove all the dead rats from inside it. Once that is done, bleach the entire wall with water and dish soap. Let it sit overnight before rinsing it with clean water in the morning.

If you have a dead rat smell on your wall, don’t worry, you can get rid of it. There are several different methods that you can try, some of which are listed below. Just be sure to pick the best one for your specific situation and follow the instructions carefully.

Some Tips and Suggestions

1. Inspect your entire home, basement to attic, for any other signs of rats. Seal up any openings larger than a quarter inch.

2. Look for droppings or urine stains to indicate that rats have been present.

3. If you have a cat or dog, they may help catch the rats.

4. Place traps in areas where rat activity has been noted. Many types of traps are available, such as snap traps, glue boards, and live traps.

5. Bait the traps with something that rats find delicious, such as peanut butter, chocolate, or hazelnut spread.

Bait the Traps With Something

6. When the trap is sprung, and the rat has been killed, you must remove it from your home by either disposing of it or relocating it to an area where other animals will eat it. This dead body must be treated as a biohazard and should not be left out in the open.

7. Once the last rat has been caught, consider installing an electronic rodent repellent device if you are still concerned about future rat problems.

How Long Does It Take for a Dead Rat to Stop Smelling?

Rats do not last long in closed spaces when they die. A dead or decaying pest smells when its body releases gasses such as methane, primarily made of hydrogen and carbon. The release of these gasses causes a dead rodent’s body to become bloated.

However, dead rats produce a pungent odor long before they get bloated, and this odor may last for weeks depending on the environment surrounding the rodent’s body. Proper ventilation will speed up the decay process for a rodent, and it will help people get rid of the dead rat smell. If no breeze or fresh air is entering the area, the stench may last for several weeks.


We have some helpful tips if you are looking for an effective way to remove the dead rat smell from your wall. First, make sure that there is no food or water in contact with the carcass and seal up any openings it may be accessed through. Next, cut a large hole into the drywall so you can get at all of its undersides and use a stiff brush to sweep out as much hair and other debris as possible before sealing off the opening again.

Finally, try using commercial products that will help mask any remaining odors until they dissipate naturally over time. We hope these tips on how to get rid of dead rat smell in wall help you resolve your issue! If you have any questions or want to know more, then feel free to comment below!
