There’s no doubt that one of the most annoying, smelly and dirty things on the planet is mould and as we live our lives in the central west of NSW. There are approx 30,000 species of fungi, however they are all similar in the fact that once they start the life cycle, it’s hard to end it. Unless you are breeding some form of exquisite cheese or creating mad science projects, nobody wants mould to appear anywhere, especially in their home.

So how does mould grow, how does it thrive, and most importantly, how do you kill it?

There are six main stages for the mould life cycle. These six stages are outlined below, however without the right conditions mould simply cannot go through this process. If you are however trying to create the perfect conditions for mould to grow, you could start with a source of moisture, mould enriching nutrients (like dead animals or rodent droppings) and humidity. Mould can grow on almost every type of material, as long the appropriate conditions are present.

Some moulds cause allergic and respiratory problems, and some produce toxins that are enormously harmful, even in slight amounts, so it’s important to understand what makes mould thrive, and even more important to know how to get rid of it.

  1. Viable mould spores lands on a surface.
  2. Sufficient Moisture Present (Air or Surface).
  3. Mould spore vegetates.
  4. Many hyphae form into mycelium.
  5. Fruiting body forms with spores.
  6. Spores released into air (certain conditions).

Hyphae Growth

The Hyphae are the cells which initiate the process of the life cycle. They release enzymes that absorb nutrients from organic materials for nutrition, and then grow into the visible portion of the fungus, called a ‘mycelium’. Their source of nutrients can range from construction dust, dirt or debris, wood, dead animals or decaying plants.

Spore Establishment

Spores grow on the ends of hyphae cells, but how well they grow depends on a number of environmental factors like light, temperature, oxygen levels, and nutrients available. If the conditions aren’t right, the spores won’t establish. If conditions are right for the establishment of spores however, they will then continue in the life cycle, ready for spreading.

Spore Dispersal

After they are established, the spores are released and carried elsewhere through the air to start the germination process again. Mould spores are extremely tough and can remain dormant for many years, even in dry environments. Mould grows best in warm temperatures, however there are some mould species that grow in temperatures as low as 2 degrees celsius.

Spore Germination

Mould spores constantly float in the air outside, and inside and are virtually impossible to eliminate. Once the spore moves to its new location, it waits for the conditions to become right for germination into the hyphae cell stage, to begin the four-stage process again.

Mould Elimination

Although mould will never be eliminated, there are a few ways you can remove it from your home, however the best way to remove problem moulds from returning is to have the professionals work their magic on your home or business.
