No matter how well you clean your house, the spores that grow into the mould are everywhere. They are microscopic and unavoidable. However, you can prevent these spores from multiplying and growing into a mould in your home.

Dryness is a significant enemy of mould growth. So, curtailing moisture is a huge part of conquering a mould problem. You may be wondering, “Does heating prevent mould?” The answer is yes. While mould loves wet and warm places, dry and heated conditions are unappealing. Ideally, you should keep all the rooms in your home above 14 degrees Celsius. However, your bathroom should be kept warmer than 23 degrees Celsius.

Why Does Mould Grow in the Bathroom?

As unpleasant as it may sound, your bathroom is the ideal environment for mould spores to live, grow, and multiply. The spores require a wet environment to survive. In addition to the typical bathroom moisture, most bathrooms are comfortably warm. The warmth speeds up the growth of mould, and it is easy to see how a colony of mould would flourish in this environment.

Like all living things, the mould in your bathroom must eat, and your bathroom is full of specks of organic matter, like skin cells and dust. So, you can see why the bathroom is the top place to find mould in your home.

Types of Household Mould

There are several types of mould commonly found in the home. Many are not especially harmful and may only cause itchy eyes or sneezing. However, some kinds of mould are toxic, even to healthy individuals. So, knowing the various moulds is vital for your health and safety. There are three threat levels of a common mould.

  1. Allergenic Mould – This mould has the lowest threat level and is common in most homes. Generally, the main health problems caused by this type of mould include mild allergy symptoms such as coughing, sneezing, sore throat, itchy, watery eyes, and skin irritation. These all tend to be shades ranging from black to brown to brownish-grey and white.
  2. Pathogenic Mould – The threat level of pathogenic mould is moderate. Typically, reactions include heavy coughing, shortness of breath, and wheezing. The most severe reactions are in small children, the elderly, and those with compromised immune systems. Specific pathogenic moulds, such as Cryptococcus species, range in colour from red, orange, and pale yellow to brown and black.
  3. Toxigenic Mould – As the name suggests, this mould has the highest threat level of all common moulds. The classification includes Stachybotrys chart arum. This is the notorious black mould mentioned in the media. The colours of toxigenic mould range from green to grey and black. However, toxic mould is distinguished by a slimy and shiny appearance regardless of the colour. Professionals should remove these types of mould as they can cause severe reactions, including respiratory failure.

Small amounts of mould are generally harmless, however, once it builds up, it can cause serious health concerns.
