Mushroom Growing Out of a Wall in Your Home: Causes and Cure

Mushrooms are delicious, nutritious, and fun to cook with. But mushrooms also cause problems for homeowners especially when you find a mushroom growing out of a wall in your home. Mushrooms can grow out of walls, ceilings, and floors, causing damage to property and even health hazards when they get bad enough.

In this article, we’ll look at how mushrooms grow out of walls, why they do it, and more importantly how you can get rid of them. We’ll also look at how to prevent mushroom growth from happening again in your home and what you’ll need to address.

Mushrooms Growing Out of Wall in Your Home

When you discover a mushroom growing out of a wall in your home it can be a frightening experience for any homeowner. In most cases, these mushrooms are harmless and can easily be removed with warm water, a damp cloth or towel, or a brush. However, if the fungus is left unchecked, they may cause damage to your bathroom floors, walls, and home.

Poor Ventilation in Your Home

Mushrooms growing in your house typically signal that there is too much moisture present in your home or the humidity is way too high. You may even have other water damage in your home that you aren’t aware of. This could come from leaking pipes, condensation from air conditioning or other sources of high humidity. It’s important to address the source of the moisture even after removing any mushrooms as doing so will help prevent them from coming back.

Once you’ve removed the mushrooms, it’s essential to find and fix the source of the moisture problem. Make sure that all pipes and plumbing fixtures are properly sealed and insulated, and check your air conditioning system to ensure it’s working correctly. If necessary, you may need to invest in a dehumidifier or other moisture control device to reduce the humidity level in your home.

Here are some bathroom dehumidifiers from Amazon which can reduce humidity in your home:

Can These Mushrooms Be Dangerous for People or Pets?

The answer to this question depends on the type of mushroom that is growing in your home. Some mushrooms can be toxic and harmful for humans, animals, or both. It is important to understand which types of mushrooms are more likely to be dangerous in order to prevent any potential illnesses or harm from occurring.

Black Mold and Mushrooms

One problem you may have a problem with along with mushrooms is mold. Mushrooms and mold can grow in the same environment, so it is important to be able to differentiate between the two. It is possible for some mushrooms to release mycotoxins, which are toxic substances that can be released when the mushroom is disturbed or come into contact with moisture. These toxins can be inhaled and may cause irritation, breathing issues, and even illness in some cases.

Removing Mushrooms from Your Home’s Walls

If the area is small where the mushrooms are located, you can typically remove the mushrooms and mold growth yourself. It’s important to identify the type of mushrooms you are dealing with and if there is any black mold. This can be done by taking a sample and having it identified by a mold professional or mold remediation company. In any case you’ll need to wear proper safety equipment such as a breathing filter and a pair of rubber gloves.

Using Bleach to Remove Fungi

Once you have identified the type of mushroom, there are several methods that can be used to remove them. The most common approach is to use a bleach and water solution. This can be applied with a brush or spray bottle directly onto the surface of the wall where the mushrooms are located. It’s important to pay attention to any surrounding areas as well, since the spores can spread quickly.

Use a Fungicide

Another option is to use a fungicide, which is a chemical that is specifically designed to kill the fungi. The fungicide should be sprayed directly onto the area and left for some period of time before being wiped away with a damp rag. Make sure to wear protective equipment when using this as well, since it can be hazardous to your health.

Finally, if there are larger patches of mushrooms, it may be necessary to scrape them off the walls manually. This should be done with caution, as mushrooms can cause serious damage if not removed properly. Be sure to wear safety gear such as goggles and gloves when doing this.

Once all of the mushrooms have been removed, you’ll want to ensure that there is no remaining moisture in the area and that the source of moisture has been repaired. You can do this by using a dehumidifier or other methods to reduce the humidity in the air. Additionally, it’s important to ensure that there is proper ventilation in the area by using a ventilation fan or air vents which provide fresh air.

Providing an Environment for Mushrooms to Flourish Indoors

Mushrooms can often be found growing in damp, dark and humid areas of a house. They can grow on walls due to the accumulation of moisture and high levels of humidity in that area, as fungi thrive in moist conditions. Under sinks and shower cubicles are ideal places for mushrooms to grow as they have the key ingredients usually for the presence of mushrooms. Unwanted water from leaking pipes, overflowing gutters or other water intrusion problems are often the source of the moisture, and the fungi can thrive in these conditions.

Mushrooms need specific environmental factors to grow and spread. They require a damp area with few contaminants, such as dust, dirt and other debris that can inhibit their growth. The walls of your home provide an ideal environment for mushrooms; they are generally warm and humid due to poor air circulation, and may have cracks or crevices that provide a perfect hiding place for the fungi to grow.

Mushrooms are also attracted to decaying organic matter like old wood, insulation and drywall. If these materials are present in your walls, then they can provide food sources for the fungi to feed on leading to an increase in their growth and spread.

Finally, mushrooms can also be the result of an underlying problem with your home’s plumbing or ventilation systems. If the pipes are leaking, then this can cause moisture to accumulate in certain areas of the walls and provide a perfect environment for fungi to thrive. Poor ventilation can also lead to inadequate air flow which encourages the growth of fungi.

Preventing Mushroom Growth in a Home

Mushrooms love warm, humid environments and often find their way into our homes. Fortunately, there are several steps you can take to reduce the chances of mushrooms growing in your home.

Increase Ventilation

The first step is to increase ventilation by opening windows or running fans near moisture-prone areas such as bathrooms and kitchens. This will help keep the air circulating and reduce the chance of humid, still areas that fungi love.

Moisture and Water Sources

Additionally, you should inspect your home regularly for any moisture leaks or seeps. This can be done with a dampness meter or simply by looking out for signs such as mold or mildew. If you find evidence of leaking, it is important to have it fixed as soon as possible.

Finally, it is important to keep the humidity in your home under control. You can do this by investing in a dehumidifier or installing an efficient ventilation system. This will help reduce the amount of moisture in the air and make it less likely that mushrooms will start to grow.
