What You'll Learn
High temperatures
Extreme temperatures affect mushroom spore viability. High temperatures, especially those exceeding 140°F, quickly destroy spores. UV light from the sun also sterilises exposed spores, reducing their viability.
When dealing with mushroom spores, it is important to wear protective gear, such as gloves, to prevent exposure to potentially poisonous spores. The first step is to manually remove visible mushroom bodies by scooping them out and ensuring that the base is also removed to prevent regrowth. These should be disposed of in sealed bags to prevent spore dispersal.
After physical removal, high temperatures can be utilised to destroy any remaining spores. This can be achieved through various means, such as using specialised equipment or natural sources of high temperatures. It is important to ensure that the affected area is thoroughly heated to prevent any surviving spores from regrowing.
Additionally, high temperatures can be combined with other chemical agents for increased effectiveness. For example, a mixture of vinegar and water can be sprayed onto the affected area after applying heat. This will change the pH of the environment, making it inhospitable for spore growth.
By understanding the role of high temperatures in killing mushroom spores, individuals can employ effective strategies to eradicate unwanted mushrooms and prevent their regrowth.

UV light
UV-C light, in particular, is a powerful form of UV light that can kill spores. It is often used for tough disinfection on an industrial scale. When using UV-C light, it is important to consider the spectral range of the light and the distance to the target object. Direct exposure to UV-C light can kill 99.9% of bacteria in 60 seconds. However, it may take longer, around 20 to 60 minutes, to kill fungal spores.
To effectively utilize UV light to kill mushroom spores, it is crucial to ensure that the light reaches all exposed spores. This may involve moving the light source or the target objects to achieve comprehensive coverage. Additionally, combining UV light treatment with other methods, such as physical removal techniques, can enhance the effectiveness of spore eradication.
While UV light is a powerful tool, it is important to use it safely and responsibly. Proper protective equipment, such as gloves and eye protection, should be worn when handling UV light equipment to avoid any potential harm to one's self or others.
By understanding the properties and requirements of UV light, one can effectively harness its power to kill mushroom spores and prevent their regrowth.

Chemical agents
Bleach
A common disinfectant, bleach destroys spore cell walls through oxidation.
Hydrogen Peroxide
This chemical agent oxidises organic material, disrupting spore integrity.
Vinegar
Horticultural vinegar or regular vinegar changes the pH of the environment, killing spores. When using vinegar, it is recommended to mix 4 parts water with 1 part vinegar in a spray bottle and mist the affected area. This process should be repeated for 5 days to prevent regrowth.
Baking Soda
Baking soda raises the pH of the soil, creating an inhospitable environment for mushroom spores. Dissolve 2 tablespoons of baking soda in a gallon of water and pour the solution over the affected area, allowing it to drain freely. Similar to vinegar treatment, this process may need to be repeated multiple times to see results.
Dish Soap
Dish soap helps penetrate and break down spore membranes. Mix 1-2 tablespoons of dish soap with 3 gallons of water and pour the mixture into the soil or use a spray bottle for targeted application.
Commercial Fungicides
Commercial fungicides can be effective in eliminating mushroom spores, but they may not address the underlying issues. It is important to follow the product instructions for application rates and methods.

Fungicides
While some people may consider mushrooms growing in their lawn a sign of good soil quality, others may find them unsightly or dangerous, especially if they have children or pets. Mushrooms can be toxic, and their spores can be easily blown about the yard in the wind, leading to further reproduction.
Natural fungicides can also be used. Vinegar, for example, is an acidic fungicide that can be mixed with water and sprayed onto the infected area. The acetic acid in vinegar will kill the mushrooms, but it will also kill anything else it comes into contact with, so caution is advised. Baking soda, on the other hand, can be used to raise the pH of the soil, creating an inhospitable environment for mushrooms. This method requires dissolving baking soda in water, aerating the soil around the mushrooms, and then pouring the solution over the area. It may need to be carried out several times to see results.
Dish soap is another option for a natural fungicide. A mixture of dish soap and water can be poured into the soil to prevent mushroom growth. It can also be used to penetrate and break down spore membranes.
In addition to fungicides, there are other methods to kill mushroom spores, such as heat, UV light, and physical removal techniques.

Natural solutions
While mushrooms can be beneficial to lawns, helping to break down dead material and return nutrients to the soil, they can also be a nuisance, especially if they are toxic. Here are some natural solutions to kill mushroom spores:
Natural fungicides
Natural fungicides such as vinegar can be used to kill mushroom spores. Mix one part vinegar with four parts water and spray directly onto the mushrooms. The acetic acid in vinegar will kill the mushrooms, but it will also kill anything else it comes into contact with, so be careful where and when you spray.
Baking soda
Baking soda can be used to raise the pH of the soil, creating an environment that is less conducive to mushroom growth. Dissolve two tablespoons of baking soda in a gallon of water and aerate the soil around the mushrooms before pouring the mixture over them. Be careful not to overwater, as this will not be effective in controlling mushrooms.
Dish soap
Dish soap is another effective natural treatment for killing mushroom spores. Mix a few drops of dish soap with water in a spray bottle and spray directly onto the mushrooms. This method can also be used as a preventative measure, helping to keep mushrooms away.
Preventative measures
The best way to deal with mushroom spores is to prevent them from growing in the first place. Address the underlying conditions that promote mushroom growth, such as excess moisture, organic debris, and poor airflow. Maintain a healthy lawn, keep soil, compost, and mulch in dry, well-ventilated areas, and store gardening materials properly to deter spore proliferation.
Competitive fungi
Introducing competitive fungi, such as Trichoderma, to your soil or compost can help to naturally reduce mushroom spore viability. These fungi can outcompete mushroom spores for nutrients and space, secreting enzymes and toxins that inhibit spore development.
