Causes of Mushroom Growth Indoors

If you have found mushrooms growing in your house, don’t be afraid! The actual mushrooms growing are probably harmless but hiding a deeper problem. Moisture and humidity create an ideal environment for fungi to thrive, leading to mushroom growth.

Excess moisture from leaking pipes, poor ventilation, and water damage contribute to a conducive environment for mushrooms to grow indoors. Most commonly, when a building floods and and is left to dry out on it’s own, fungi thrive. However, so do fungal spores.

The timber in the building provides a food source for fungi, promoting mushroom growth. This is also known as Dry Rot. Dry Rot is named after the condition that the rotten wood is left in once the mushrooms growing inside and on top have sucked out the moisture present.

 Identification of Common Indoor Mushrooms

Areas prone to mould growth and mushrooms growing in your home are carpets, corners, walls and basements. This is due to excess moisture inside the fibres of carpets or within the wood because of poor ventilation. There are several different types of mould species that can be found on the mushrooms inside your home.

Common mould species found on mushrooms include

  • Aspergillus
  • Penicillium
  • Cladosporium

The mushrooms growing inside your home are likely to be relatively harmless but left for long enough and severe cases can produce mycotoxins which cause some health risks.

Health Risks Associated with Mushroom Growth

Indoor mushrooms can be a real danger to people due to mycotoxins released by mould spores, causing potential health risks. People may experience health effects from being exposed to , including symptoms like respiratory issues, allergic reactions, and more.

Mould exposure can be particularly harmful to the well being those with allergies and cause serious respiratory problems for those with respiratory conditions such as asthma or emphysema. If you have any underlying health issues, it is important that you find the root cause of the damp, mould and mushrooms growing.

Removing Mushrooms from Your Home

It may be tempting just to remove mushrooms as soon as you see them growing in your home. However, cleaning and disinfecting affected areas is crucial to removing mushrooms and preventing future growth. Removing mushrooms without addressing the underlying issue of moisture and mould growth will not provide a permanent fix.

Professional help and mould removal services may be necessary for extensive or persistent infestations. A damp survey will help identify areas of concern and how to combat persisting damp conditions.

Preventing Future Mushroom Growth

Creating a healthy living environment by controlling moisture and mold growth can prevent mushrooms growing in the first place. There are many preventive measures, from proper ventilation to good maintenance.

  • Maintain optimal humidity levels between 30-50%. This is essential to preventing mushroom growth. Often, proper ventilation can be enough to prevent damp from ever developing.
  • Mold spores are a precursor to mushroom growth, and their presence indicates a larger issue. Eliminating spores by improving air circulation, fixing leaks, and removing organic materials can prevent future mushroom growth.
  • Preventative measures should be taken whether you have noticed damp or mushroom growth or not. Regular inspections are important, particularly in older buildings and basements.
  • Another important preventive measure to avoid damp and mushrooms growing inside is to keep humidity in your home at an optimal level. Humid environments are a breeding ground for excess moisture, black mould and fungus. Your home should be at around 40%-55% humidity

If you are struggling to prevent mould or mushroom growth, have excess damp or any type of water damage, it may be necessary to have a professional damp survey to properly assess the problem.

Moisture Control and Ventilation

Mushroom growth is often a symptom of a larger issue, such as water intrusion, poor ventilation, or dry rot. Keeping control of moisture levels in the home is the best prevention technique. For example, kitchens and bathrooms should always be fitted with extractor fans (sometimes known as exhaust fans).

Another cause of moisture is water leaks, it’s important to check the most likely low light places for excess moisture such as basements for damp or attics for a leaky roof. Be sure check dark corners where you may find mushrooms growing.

Proper ventilation is key when moisture build up is an issue and you want to avoid persisting damp, mould or mushrooms appearing. Keeping windows open where possible to allow natural airflow alongside extractor fans in humid rooms will provide great ventilation. But sometimes it isn’t enough. A dehumidifier is great for keeping humidity low and has been shown to have great health benefits too.

Conclusion

Mushroom growth in your home can be a sign of underlying issues, such as dampness or dry rot. An affected area left untreated can cause structural damage, health issues and trigger allergies.

By understanding why mushrooms grow in the home, addressing the underlying issue, and taking preventive measures, you can create a healthy living environment and prevent future mushroom growth.
