For a long time, I had only heard that you should use bleach to remove mold from areas in your house. But when I got my own house a few years back, I was primarily using green and natural products and so I wondered – Can you remove mold from your house naturally?

Yes, you can remove mold from your house naturally. There is a variety of natural household products that you can use to remove mold in your house. You can also use essential oils.

Removing mold from your house naturally avoids using harsh chemicals that you can breathe in, come in contact with your skin, or expose to your pets or family. 

Before exploring these natural products and natural ways of removing mold from your house, let’s briefly discuss what mold is, how it grows, and the different types of mold found in your house.

What Is Mold?

Mold is a fungus that reproduces through very small spores. The spores will tend to grow into mold in areas that contain a lot of moisture. Mold needs moisture, the right temperature, and a source to feed on.

The most common indoor house molds are below:

Cladosporium – Usually grows in humid and damp areas in your home. Can appear as brown, yellow, olive green, or black. 

Penicillium – Grows in damp areas or where leaks are in your home. Also very common to find on food like fruits, vegetables, bread, and cheese.  Mostly blue or green but also white or yellow.

Aspergillus – Found in humid and damp areas in your home. Also found in dead leaves and compost piles that are up against your home’s foundation. Aspergillus is usually black.

Stachybotrys Chartarum – This mold is commonly referred to as black mold. It is often seen in homes after flooding has occurred. Usually dark greenish-black or black.

How Do You Know You Have Mold in Your House?

Detecting mold in your home will not be hard to do now that you know what it looks like. Another indicator of mold is that it will usually have a musty smell. 

Always check areas in your home that have been flooded, where water has leaked, or where moisture tends to accumulate. This could be in areas like the bathroom, basement, laundry area, crawlspace, attic, closets, windows, or under the kitchen sink.

Now that you know the most common types of mold that can be found in your house and where to look for it, let’s discuss mold in your house and if you can remove it naturally, and what to use to naturally remove it.

Can You Remove Mold Yourself

As mentioned earlier, yes, you can remove visible mold yourself.  But beware that although the mold is not alive and growing anymore the mold particles will most likely still be in the air. 

If you are someone who has any of the health factors that cause you to get sick from mold you may want to avoid removing mold yourself. But if you do get sick from mold and still want to remove it from your house you will need to wear the appropriate personal protective equipment.

Can You Kill Mold?

You can kill mold and you can use natural household products to do it. But like removing it, the mold particles will more than likely still be in the air. And if you have any health factors mentioned earlier the mold particles in the air can still cause you to get sick.

Can You Remove Mold on Walls?

Mold is going to show up in the rooms of your house that have excess moisture. If you have ever had flooding or a leak in your home (especially in the basement), you may find mold on your walls a lot of times. And yes, you can remove mold from the walls of your house and you can do it naturally.

There are a variety of natural ways to remove mold from the walls depending on the damage and amount of mold on your walls. We will touch on them soon but right now let’s cover the most common types of mold you can remove mold from.

Can You Remove Mold from Drywall?

Drywall is a porous material and mold can grow on both sides of it. You can remove mold from drywall but you need to monitor it regularly because it may grow back especially if the spores are not killed and removed. 

Can You Remove Mold from Plaster Walls?

Plaster walls are not porous but mold can still grow on the paint or dust on it. You can remove mold from plaster walls easier than drywall but to prevent it from growing back you will still need to eliminate the excessive moisture in that area.

Can You Remove Mold from Your Shower Walls?

There are several bathroom and shower mold and mildew products on the market to clean and remove mold and consistently cleaning and using them will help prevent the mold from growing and spreading. Proper ventilation is key to preventing mold and mildew in the bathroom and shower.

How Do You Get Rid of Mold in a House Naturally?

Now that we have established that you can kill and remove mold from your house, let’s discuss the natural household products and essential oils that can help you do it and how to do it.

Does Vinegar Kill Mold?

Outside of bleach, vinegar is probably the most common go-to household product for cleaning mold. Vinegar does kill mold (killing 82% of known mold species) and it’s all-natural. It’s also acidic and contains antifungal and antibacterial properties.

Vinegar is also great for removing mold on the glass shower door. And you can wash your fruit in it to remove any mold or prevent mold from growing on it.

Baking soda is extremely useful for cleaning and removing odors from your house. And yes it can also remove mold from your house naturally as well as moisture.

  1. Make a baking soda paste with two parts baking soda and one part water (amounts will vary depending on the amount of mold you are trying to remove).
  2. Stir the paste thoroughly then apply it to the area that contains the mold.
  3. Let it dry.
  4. Remove it using a damp sponge, rag, or microfiber cloth. If necessary, spray vinegar onto the paste to help break up and remove the mold.

Does Lemon Kill Mold?

Yes, lemon does kill mold. Lemon, like vinegar, is acidic and also contains antifungal and antibacterial properties. But unlike vinegar, it leaves a clean and pleasant smell after you have used it.

How to remove mold using lemon:

  1. Cover the molded area with pure lemon juice (either by squeezing, juicing, or using premade lemon juice).
  2. Let it sit for 5 – 10 minutes.
  3. Wipe it up or scrub with a damp cloth or sponge.
  4. For hard to remove mold stains repeat steps 1 – 3.

Can You Use Hydrogen Peroxide to Clean Mold?

Everyone probably has a bottle of hydrogen peroxide laying around their house (most likely in the medicine cabinet) and has used it for disinfecting a cut or scrape on their skin. It is great not only for disinfecting but cleaning up around your house including mold. 

Research shows that hydrogen peroxide can hinder mold growth on solid surfaces that are not porous.

How to clean mold using hydrogen peroxide on non-porous surfaces:

  1. Put 3% hydrogen peroxide into a spray bottle and spray the moldy surface until saturated.
  2. Let the hydrogen peroxide sit for 10 minutes.
  3. Gently use a microfiber cloth or sponge to remove it and the mold. Apply more pressure if needed for tougher mold stains.
  4. Repeat if necessary.

Like bleach, hydrogen peroxide can whiten or bleach certain materials. Spot test the surface first before covering the whole area of mold.

There are a wide array of essential oils on the market. But there is a handful that can be used to combat mold. Here are some below:

  • Tea Tree
  • Juniper
  • Cinnamon

Can Mold Be Completely Removed from a House?

You can do the best you can to completely remove mold yourself or hire a mold remediation expert who will professionally clear out the mold in addition to the mold spores in your home. But if the conditions are right, mold is always going to grow. 

How to Prevent Mold in Your House

As mentioned earlier mold needs moisture, the right temperature, and a source to feed on to grow in your house. So to prevent it from growing try to minimize these factors. 

Moisture/ Humidity

How-to-Prevent-Mold-in-Your-House

To prevent mold from growing in your house you need to remove excess moisture and lower the humidity. As mentioned earlier, areas in the house like the bathroom, basement, laundry area, crawlspace, attic, closets, windows, or under the kitchen sink tend to accumulate excess moisture.

The most common and probably the easiest way to remove excess moisture is by using exhaust fans and dehumidifiers in these areas. Exhaust fans can be especially useful in the bathroom and kitchen. It is recommended to keep the humidity level in your home to 50% and you can do that by setting your dehumidifier to that level.

Temperature

The ideal temperature for mold is between 60° F and 80° F degrees. Mold will not grow below 40° F. Try to keep your house’s temperature on the lower end of this range. 

Dust and Dirt

Dust and dirt are food sources for mold. So clean, dust, and vacuum the dirt and dust in your house as much as you can or hire a housecleaner.

Regularly changing your HVAC filters and furnace or air conditioning filters can also help prevent dust, dirt, and mold from entering your home’s air.

Conclusion

As you can see you can remove mold from your house naturally by yourself using household products and essential oils. The most common household products and essential oils for removing mold in your house are vinegar, baking soda, lemon, and hydrogen peroxide. The most common essential oils are Tea Tree, Juniper, Cinnamon, Thyme, and Patchouli.

The EPA (Environmental Protection Agency) recommends that if the area you are removing mold from is larger than 10 square feet refer to this EPA guide for Mold Remediation in Schools and Commercial Buildings. The EPA also recommends that if it’s larger than 10 square feet and you want to hire a contractor to remove the mold in your house make sure they have experience cleaning up mold.
