What You Need to Know and How to Keep it Out of Your Home

Mould is not only unsightly but can also pose serious health risks if left untreated. For those committed to low-tox living, understanding how to prevent and manage mould in the home is essential for maintaining a safe, healthy environment. Let’s look at what mould is, why it’s a problem and most importantly, how you can prevent it from taking root in your home.

What Is Mould? Mould is a type of fungus that thrives in damp, warm environments. It can grow on a variety of surfaces, from walls to clothing and often appears as black, green or white patches. While mould plays an important role in nature by breaking down dead organic material, it becomes a problem when it invades our homes. Spores released by mould can trigger allergic reactions, asthma and even more serious respiratory issues, especially in vulnerable individuals like children, the elderly and those with compromised immune systems.

Why Is Mould Dangerous? Beyond the visible presence of mould, the real concern lies in the microscopic spores it releases into the air. These spores can easily be inhaled, leading to a host of health problems. Common symptoms of mould exposure include sneezing, coughing, skin irritation and in more severe cases, difficulty breathing and fatigue. Prolonged exposure to mould in the home can worsen pre-existing health conditions and cause long-term respiratory issues.

Additionally, mould can damage the surfaces it grows on, leading to costly repairs. It can weaken structures, ruin fabrics and leave behind a persistent musty odour that can be difficult to eliminate.

How to Prevent Mould Growth in Your Home 
The best way to manage mould is to prevent it from forming in the first place. Here are some effective steps you can take to mould-proof your home:

  1. Control Humidity Levels
    Mould thrives in environments with high humidity, typically above 60%. Using a dehumidifier in areas like bathrooms, kitchens and basements can help reduce moisture levels and make these spaces less conducive to mould growth. It’s also important to ensure good ventilation in these areas, especially after activities like cooking or showering.
  2. Fix Leaks Immediately
    Whether it’s a dripping tap or a leaking roof, any form of water ingress can lead to the rapid growth of mould. It’s essential to repair leaks as soon as they’re discovered and dry out any affected areas to prevent moisture build-up.
  3. Dry Wet Areas Promptly
    Whether it’s a spill on the carpet or a wet bathroom floor, it’s important to dry wet areas as soon as possible. Leaving water to sit can provide the perfect environment for mould to grow, especially in hidden areas like under rugs or behind furniture.
  4. Use Mould-Resistant Products
    Consider using mould-resistant products, such as mould-resistant paint and drywall, especially in areas prone to dampness. These products can help reduce the risk of mould developing in the first place.
  5. Regular Cleaning
    Regular cleaning, especially in moisture-prone areas, is key to preventing mould. Natural cleaning products like vinegar and bicarbonate of soda can effectively remove mould without introducing harmful chemicals into your home.

What to Do If You Already Have Mould? If mould has already taken hold in your home, it’s important to act quickly. Small areas of mould can often be dealt with using natural cleaning solutions. Check our Mould Cleaner recipe here! For larger infestations, it may be necessary to call in professionals, as improper cleaning can cause spores to spread and exacerbate the problem.

When cleaning mould yourself, be sure to wear protective gloves and a mask to avoid inhaling spores. Ventilate the area well. Opt for natural cleaners such as vinegar, which has antifungal properties and can kill mould effectively.


Mould is a serious issue that can affect both your health and your home, but with the right prevention strategies, it’s possible to keep it at bay. By managing humidity, repairing leaks and using natural, mould-resistant products, you can create a safe, low-tox environment for you and your family. If mould is already present, act quickly to clean it or seek professional help.
