Destroy spores with high temperatures, UV light, or chemicals like bleach and vinegar
Destroying mushroom spores can be challenging due to their resilience and ability to survive in harsh conditions. However, high temperatures, UV light, and specific chemicals can effectively kill them.
High temperatures above 140°F destroy mushroom spores quickly by breaking down their structure. This method is particularly effective in controlled environments, ensuring direct heat exposure to the spores.
UV light, especially UV-C, is another powerful tool against mushroom spores. It breaks down their structure, reducing their viability. Sunlight is a natural source of UV light, but for faster and more targeted applications, artificial UV-C wands can be used.
Chemicals like bleach, hydrogen peroxide, vinegar, baking soda, and dish soap are potent agents that kill mushroom spores through oxidation and pH alteration. Bleach, a common disinfectant, destroys spore cell walls through oxidation. Horticultural vinegar changes the pH of the environment, creating conditions inhospitable to spores. Baking soda raises the soil pH, making it difficult for spores to survive. Dish soap helps penetrate and break down spore membranes.
When using chemicals, it is important to follow instructions and take the necessary safety precautions. Additionally, combining multiple methods, such as high temperatures and chemical agents, can be more effective in ensuring the complete destruction of mushroom spores.
By understanding the vulnerabilities of mushroom spores, you can employ these strategies to effectively destroy them and address any infestations or unwanted growths.

Remove mushrooms by hand, with a vacuum, or rake and immediately bag them
Mushrooms in your yard are usually a sign of healthy soil, but they can be unsightly and may be dangerous if you have children or pets. To get rid of mushrooms, you can remove them by hand, with a vacuum, or rake, and then immediately bag them. Here's how:
Removing Mushrooms by Hand
When removing mushrooms by hand, it is important to wear gloves to protect your hands from potentially poisonous spores. Simply pull each mushroom cap out of the ground and place it directly into a plastic bag. Be sure to get to the mushrooms as soon as you see the caps appear, as leaving them too long will result in the release of spores, leading to more mushrooms. Once the bag is full, tie it tightly and dispose of it in a trash can or incinerator.
Using a Vacuum
If you have a large number of mushrooms, you can use a vacuum to remove them quickly and efficiently. Again, be sure to wear a mask to avoid inhaling spores. Vacuum the mushrooms, being careful not to disturb the spores, and then immediately empty the vacuum bag or canister into a plastic bag. Seal the bag tightly and dispose of it properly.
Raking Mushrooms
Raking is another option for removing mushrooms, but it can increase the chances of spores spreading across your lawn. If you choose to rake, use a power rake or lawn rake to gently loosen and remove the mushrooms from the soil. Collect the mushrooms and rake them into a pile, then use a shovel or your hands to place them into a plastic bag. Seal the bag tightly and dispose of it in the trash.
Preventing Mushroom Regrowth
To prevent mushrooms from regrowing, you can apply a natural fungicide, such as horticultural vinegar diluted with water, to the areas where the mushrooms were growing. You can also use a quick-release, inorganic nitrogen fertilizer, which will speed up the breakdown of organic matter, reducing the food source for mushrooms. Additionally, improving drainage in your yard by aerating your lawn or fixing poorly draining spots can help prevent mushroom growth.

Use nitrogen fertiliser or dish soap to prevent mushroom growth
Mushrooms are part of a fungus that grows underground. They are beneficial to lawns as they help break down dead material and return nutrients to the soil. However, they can be a nuisance, especially if they are toxic and you have children or pets. Simply plucking mushrooms is not a solution as they are often much larger beneath the surface of the soil. To prevent mushroom growth, you can use nitrogen fertiliser or dish soap.
Nitrogen Fertiliser
Nitrogen fertiliser can be worked into the soil where mushroom caps were growing to kill the roots and prevent regrowth. The fertiliser quickens the decomposition of organic matter, leaving the mushrooms with nothing to feed off of. It is recommended to use 1 pound (453.59 grams) of nitrogen for every 1,000 square feet of lawn. Do not use slow-release or water-soluble nitrogen fertiliser. Consider adding some phosphorus and potassium as well. A mixture of 3 parts nitrogen, 1 part phosphorus, and 2 parts potassium is recommended.
Dish Soap
Dish soap can be mixed with water and poured into the soil to prevent mushroom growth. It damages the mushrooms and the network of hyphae that support their growth. It is recommended to mix 3 tablespoons (45 mL) of dish soap with 2 gallons (7.5 L) of water. This mixture will not harm your lawn as dish soap does not contain anything that could potentially kill grass. It also acts as a pesticide, killing any bugs that might be attacking your plants or grass. However, it is important to note that using high concentrations of soap can affect the soil's pH balance and impact grass growth. Therefore, measuring the pH of your soil before applying the mixture is recommended.

Improve drainage and sunlight in your garden to stop mushrooms from growing
Mushrooms thrive in shady and damp conditions, so improving drainage and increasing sunlight in your garden can help stop them from growing.
Improving Drainage
To improve drainage, you can aerate your lawn, which will help to eliminate standing water and improve soil aeration. This can be done mechanically or with a garden fork. Aeration helps create healthy soil by improving drainage and allowing essential ingredients to mix more effectively with the soil, making it inhospitable for fungi.
You should also ensure that surface water from rain or melted snow flows away from your home's foundation. Consider investing in a good drainage system that carries excess moisture away from areas where it could pool, such as towards flower beds or shrubbery.
Increasing Sunlight
To increase sunlight in your garden, cut back any overhanging branches, limbs, or other obstructions. Trim trees and bushes, and mow more often to let additional sunlight through. If the shade is due to tree and shrub overgrowth, trim away any dead branches and thin out denser crowns of trees and shrubs so they don't block sunlight.
In addition to improving drainage and increasing sunlight, you can also remove decaying organic matter, such as leaves, grass clippings, and animal waste, which mushrooms feed on.

If mushrooms are growing indoors, remove the affected area and use a dehumidifier
If mushrooms are growing indoors, it is best to remove them as they can be dangerous if ingested and can cause mould issues. Mushrooms thrive in damp environments and require a food source, oxygen, and an ideal temperature to grow.
To get rid of mushrooms growing indoors, start by removing the affected area. Cut the mushrooms as close to the growing surface as possible using a box cutter, putty knife, or a similar object that can cut through the mushroom's thick stem. Place the removed mushrooms in a bag and discard them.
Next, address the source of moisture that is fuelling the mushroom growth. Mushrooms could indicate underlying issues such as leaks or poor ventilation. Check for any leaks in plumbing, roof vents, windows, or toilets, as these can provide a constant supply of humidity and water, creating ideal conditions for mushrooms. Fix any leaks and improve ventilation by running a fan or using a dehumidifier to reduce moisture levels.
After addressing the moisture source, clean the affected area. Apply a mixture of vinegar and water or a solution of one part bleach to three parts warm water to the surface. Scrub the area with a sponge or cloth, ensuring proper ventilation during the process. Wear a mask to protect yourself from inhaling any spores or chemicals.
Additionally, if the mushrooms have stained any wooden surfaces, create a paste by mixing oxalic acid and water. Apply the paste to the stains using a soft cloth and leave it on until the stain disappears. Then, remove the paste with a clean towel.
