Many complain that their laundry room always seems to have a foul fecal odor. This foul stench is typically produced by the build-up of germs, lint, and dirt in the washing machine and dryer. There are simple solutions available if you’re experiencing this problem.
This article will discuss the most prevalent reasons for “laundry room smells like poop” and how to eliminate it. Your laundry room can smell as fresh as when you first moved in with just a few easy steps.
Why Your Laundry Room Smells Like Poop
There are instances when the laundry room has a poopy odor because of the items being washed. Garments soiled or in contact with human or animal excrement can undoubtedly add to an unpleasant odor. However, this is not always the root of the problem. Some of the causes might be as follows.
1. Overflowing Lint Trap
One typical source of unpleasant odors in the laundry room is lint traps that have become overloaded. Lint accumulates around and in the dryer, holding moisture and providing a fertile breeding ground for mold and germs. Furthermore, the lint might obstruct the ventilation system, preventing the release of stale smells.
Maintaining a pleasant aroma in the laundry room requires frequent ventilation system maintenance, including emptying and cleaning the lint trap. However, if the odor persists, you may want to have a specialist take a look.
2. Animal Droppings
Sadly, animal feces may also be a major cause of unpleasant scents in the laundry room. Pet feces may easily find its way into the laundry room if you have cats or dogs in the house, and you may find it challenging to get rid of it completely.
Dog feces have a foul odor that lingers for a long time, so cleaning up after your dog (and any other pets) as soon as possible is essential. However, there may still be residues of germs that contribute to an unpleasant smell, even after you have cleared up the mess.
3. Moisture Buildup
Your laundry area may start to smell bad because of excess moisture. This is especially true if there is a lack of ventilation since this will trap moisture and provide ideal conditions for the growth of mold and germs.
Also, the laundry room might develop an unpleasant stench if you don’t let it air out after washing clothing with detergent and fabric softener.

Keeping up with washing tasks can be discouraging and difficult if the laundry room smells terrible. It is crucial to determine what is causing the odor and eliminate that source so it doesn’t reoccur.
4. Improperly Ventilated Dryer
A poorly ventilated dryer is usually the culprit for the foul smell. Warm, wet air produced by a dryer that isn’t linked to an outdoor vent can’t escape the room. This provides a fertile breeding ground for bacteria and mold, producing odors like feces. There’s also lint accumulation in the dryer’s fan, blocking it.
5. Dirty Clothes Hamper
Foul odors in the laundry room may also originate from dirty laundry hampers. If you empty your hamper frequently, germs and mold will quickly grow, making your clothes laundry room good. Fabric hampers, in particular, have the added disadvantage of attracting and holding on to moisture and unpleasant scents.
In addition, bacteria will continue to increase if soiled garments are stored in plastic bags where air cannot flow. The resulting odor may be difficult to eradicate.
6. Poor Drainage System
Laundry room odors might also be caused by a drainage system that hasn’t been properly installed or maintained. Water and waste can build up in the pipes if the drainage system isn’t functioning correctly, producing odors frequently smelling like excrement.
In addition, if there are problems with the plumbing, there may be pools of standing water that can breed harmful germs and mold. Therefore, dealing with a plumbing problem as quickly as possible is crucial if you detect any.
7. Clogged Pipes
A clogged piping system is another possible source of a foul odor in the laundry room. Clogged pipes may trap water and germs, which can then cause a foul stench to build up in your home. Clogs in the laundry room drain can also cause water to back into the kitchen or bathroom, generating an unpleasant odor.
And if the laundry room does not have good ventilation, the stench of the clogs will be retained in the air and impossible to get rid of. But with effort and a plumber’s assistance, you can clear out the obstruction and the stench it produces.
8. Not Cleaning The Washer
Neglecting to clean your washer is another primary source of unpleasant odors in the laundry room. Over time, the buildup of detergent and fabric softener in the washer can cause a musty odor. In addition, mold and bacteria can flourish in the humid conditions created when moisture is trapped inside the machine.
Additionally, if the washer is not completely emptied after a cycle, moist garments may become stuck inside and begin to smell. To counteract this, however, most new washing machines have an in-built self-cleaning cycle to counteract this.
9. Poorly Maintained Septic System
Laundry facilities that drain into septic systems require regular upkeep. Septic tanks require frequent emptying to prevent sewage backup and unpleasant odors. Additionally, if the tank isn’t correctly sealed, smells may seep out of your laundry room.
However, if you inspect and repair your septic system regularly, you shouldn’t have to worry about any unpleasant odors seeping out. But if you smell something strange in the laundry room, it’s time to schedule a septic tank inspection and maintenance.
How to fix “Laundry Room Smells Like Poop” Problem”
Most unpleasant odors in the laundry room may be eliminated by eliminating their source, which is usually not difficult. Here are a few suggestions:
1. Invest In A High-Efficiency, Front-Loading Washing Machine
High-efficiency, front-loading washing machines are engineered to use less energy and water than conventional top-loading washers, and their design also prevents moisture from becoming trapped in the laundry room, thereby reducing odors.
High-efficiency front-loading washing machines can also help you save up to 30% on your water and energy costs. Incorporating a wastewater treatment system can help minimize the quantity of water wasted in your septic tank and lower your water bill. Drying clothing outdoors on a clothesline is an excellent method to save money on utility expenses.
2. Place An Air Deodorizer Or Other Odor Neutralizer In The Room
Using an air deodorizer or similar odor-neutralizing products may significantly reduce unpleasant odors in the laundry room. These products assist in producing a pleasant indoor environment by capturing and neutralizing odors. Odor-masking ingredients in some products include lavender and vanilla.
You may also use vanilla-scented candles to mask unpleasant scents. You can maintain your space smelling clean and fresh by spreading the candles about the laundry area. An ozone generator also helps lessen bacterial and unpleasant odors in the air.
3. Wash All Clothing Items Separately On Hot Water Settings
Clothes that have developed an unpleasant odor may be contaminated with bacteria or other residues. Wash your clothes in hot water separately for each item to reduce this accumulation. To further assist in removing odors, add a cup of baking soda or vinegar to your washing cycle. It’s also essential to leave the washing door open while it’s not in use and to dump the water after each cycle.
Also, make it a habit to inspect and clean the laundry facilities frequently. After each cycle, remove any lint from the lint trap and clean it with a brush or a cloth to ensure a long life for the filter. Not cleaning your machine frequently might encourage the growth of mold and bacteria, which can cause unpleasant odors.
4. Clean The Washing Machine With A Mixture Of Vinegar And Baking Soda
Detergent and fabric softener residue may have built up over time, leading to the unpleasant odor you’re experiencing from your washing machine.
Use white vinegar and baking soda to clean the appliance. It’s recommended to start by filling the washer with hot water, then adding 1 cup of vinegar and 1/2 cup of baking soda. Then, after 15 minutes, put the machine at its highest speed and let the mixture run.
After completing the first cycle, rerun the washing machine using only hot water. This should help eliminate any foul odors in your washer and keep your laundry area smelling fresh.
5. Dry All Laundry Items Before Folding
It’s common knowledge that even clean laundry can rapidly develop a foul odor if left moist after washing. Always dry your clothes completely before folding them to prevent this and maintain a pleasant aroma in your laundry room.
Drop some aromatic oils into the washer’s fabric softener dispenser for an added touch of fragrance. It will also improve the laundry room’s air quality and keep your garments smelling fresh.
6. Place An Exhaust Fan In Your Laundry Room
Exhaust fans are a fantastic way to lower the moisture and humidity in a space. It can also help stop the growth of mold and mildew, which can contribute to unpleasant smells. Set the fan to a timer so that it continues to blow for at least 30 minutes after every load of laundry is finished.
This will dehumidify the space, making laundry less likely to develop a musty odor. Keep the fan clean at all times. Accumulation of dust and lint in blades will reduce efficiency. The room will continue to smell clean and fresh once the fan has been cleaned.
7. Ensure There Is Adequate Ventilation
Laundry rooms that don’t have enough airflow may develop unpleasant odors. Opening the windows and turning on the exhaust fan should help if there are unpleasant scents in the room.
A dehumidifier can further assist in lowering humidity levels, thereby decreasing the potential for musty odors to develop. An added benefit of using a dehumidifier is lessening the likelihood of mold and mildew growth.
8. Clean Regularly With Soap And Water
To maintain a pleasant aroma in the laundry room, clean it regularly using soap and water. Clean the floor, wipe off counters, and dust shelves. In addition, there are laundry-specific cleansers that you can use to get rid of odors and prevent the formation of bacteria.
You’ll need more than cleaning and dusting to maintain a pleasant aroma in the laundry room. Put some aromatic oils in the air, and it will smell great. You can also use an air freshener to maintain the room’s fresh scent.
9. Install A Carbon Monoxide Detector Near Your Washer
Carbon monoxide detectors should be installed close to laundry appliances. The sensor will sound an alarm if there is a dangerous buildup of dangerous gases in the room, giving you time to take precautionary steps. This will help maintain a pleasant aroma in your laundry area.

It is also important to frequently inspect and service the detector. The accumulation of dust and other debris can diminish the efficiency of the vents. Cleaning it every month will keep it in good operating order and prevent musty odors from spreading throughout the laundry area.

Old or inefficient plumbing is another common reason for a bathroom’s unpleasant odor. If your home is older than 20 years, consider having the plumbing system replaced.
Get in touch with an expert plumber to examine the pipes and advise on whether or not they should be changed. This is an excellent way to maintain a pleasant aroma in the bathroom.
Why Does My House Smell Like Poop After I Shower?
After many showers, soap residue and mildew can leave a house smelling like feces. You should regularly clean the shower and bathtub with water and soap to avoid unpleasant smells. Use a fan to dry the air out when you get out of the shower.
Doing so will limit the potential for unpleasant odors and mildew growth. Finally, if there are any unpleasant scents, spray them with a deodorizing spray.
Does Sewer Gas Smell Like Poop?
Yes, sewage gas occasionally has a poopy stench. The presence of methane, ammonia, and hydrogen sulfide brings this on. The combination of these gases results in an odor akin to that of decomposing excrement.
Call a plumber to evaluate the drain system and conduct any required repairs if you detect a foul odor from the pipes. Ensure all the pipes are properly sealed so that sewage gas doesn’t seep into your home.
