Mushrooms growing in your yard usually indicate you have healthy soil. However, they come in different species and most of them are toxic. Since you most likely can’t immediately identify the type of mushroom you have in your garden, the best thing to do is to remove them, especially if they spread like wildfire and you have children or pets.

Inside your home is another story, as mushrooms can grow in floorboards or in your bathroom. You may be surprised but this is a common occurrence and is a usual indicator of molds.

How Long Does It Take To Kill Mushrooms With Bleach?

Bleach can kill mushrooms soon after spraying the chemical. But this does not guarantee that the mushrooms will not come back. The most effective way of attacking mushrooms is by going after the mycelium, or the vegetative part of the fungus. 

Note that the mushrooms are the budding fruits and picking them or killing them will not completely eliminate them. Instead, dig deep into your soil and you will discover thin thread-like branches, which are the mycelia.

Meanwhile, fungus, mold, or mildew can grow in your home and may bear fruit – which are the mushrooms. Uncontrolled fungus growth becomes a real concern if it starts staining then damaging your walls.

Getting rid of mushrooms in your yard using bleach may require you to sacrifice a portion of your lawn. You may spray the bleach but expect that the surrounding grass will be affected. However, that is a much better option just so you can preserve the beauty of your entire yard.

What Type Of Bleach Should I Use To Kill Mushrooms?

As bleach has been popularly used by homeowners and gardeners as a way to effectively control mushroom growth, you might wonder what kind of bleach to use. Before you grab the household bleach like the Clorox you have at home, note that there is a certain concentration of the liquid to make it an effective fungicide.

You can’t just pour it straight from the bottle. Instead, bleach is diluted with water before spraying. In some instances, vinegar is also added for that added power to eliminate mushrooms.

Killing Mushrooms With Bleach Step By Step

Since bleach is a strong chemical that may cause irritation, always remember to use gloves before using. A household cleaning gloves, such as Mr. Siga cleaning gloves, will suffice.

In addition, put on clothes that you don’t mind bleaching or staining. Other important protective gear include goggles, especially if you know you’re sensitive to chemicals.

Below are five easy steps in killing mushrooms in your yard with bleach:

Step One

Get your spray bottle ready and mix in one part bleach with 10 parts water. This will serve as your strong cleaning agent. If you wish to amp it up a bit, add two to three tablespoons of white vinegar.

Step Two

Gently shake or swirl the bottle to ensure the liquids are mixed.

Step Three

Spray the affected part of your garden, especially the visible fungus, also known as the mushrooms. 

Step Four

Saturate the mushrooms thoroughly and allow to sit for 10-15 minutes.

Step Five

Observe if the surrounding grass is not affected, then you may continue spraying other mushrooms in your garden.

An alternative to the steps above is outlined below.

  1. Pick mushrooms from the ground. As you do this, a small hole will be made.
  2. Carefully pour the bleach solution into the hole. You should be able to see an underlying mass in the soil.

The aforementioned method is said to be also effective since the bleached area doesn’t inhibit the growth of new patches of grass. In addition, this method is said to be less damaging to the surrounding grass since only the area where the shrooms are has contact with bleach.

While this method may have worked for some people, it’s not guaranteed to work in your garden so always exercise caution and do it at your own risk. Otherwise, you might find dead grass all over.

Using Bleach To Kill Mushroom Indoors

For killing mushrooms growing inside your home, follow the same five steps above. However, it’s worth noting that bleach may be ineffective if you use it on porous surfaces, such as wooden floors. It is, however, effective at removing mushrooms and even molds in impermeable surfaces such as tiles or your tub.

While bleach can kill the visible mushrooms on porous surfaces, it doesn’t prevent its regrowth. This is because the fungus buries deep into these surfaces. You may have cleared your floors of mushrooms, but expect them to return in just a short amount of time.

What To Remember About Mushrooms

A better way to deal with mushrooms is to understand how mushrooms grow in the first place. Mushrooms thrive in wet, acidic soil so generally, promoting lawn health can keep fungal growth at bay. Regularly check your soil’s pH with a pH test kit or bring a sample of your soil for testing. A good find is Luster Leaf rapid pH test kit. 

Fertilizing your lawn with nitrogen not only helps keep your garden healthier but also controls fungus growth. And if mushroom growth is not prolific or there is only a small area where mushrooms grow, then the best thing you can do is to dig out that soil and reseed with grass.


Bleach has been a popular remedy against mushrooms and many can attest that killing mushrooms with bleach works. However, for bleach to be effective at its job, make sure it is used and applied properly.

Proper application of bleach as a fungicide for your garden requires making a solution with the right ratio of water to bleach, which is 10:1. When dealing with bleach, always remember to put on protective gear as this chemical can be irritating. 

In addition, bleach may kill off vegetation, including your grass. When you use this method, expect that your lawn will have brown patches from bleach contact. If you’re willing to make this sacrifice, then bleach should be an effective solution against mushrooms.

If you don’t mind picking mushrooms one after another, then this would be a much safer alternative that will not affect your grass.
