9 Incredible Facts About Mould You Never Knew


You don’t give mould much thought. When you do, it’s probably because the stuff suddenly shows up under a sink or on the basement walls. You grab some cleaning supplies, address the problem, and hope it doesn’t come back. Our teams take care of mould cleanup in Sydney homes and businesses every day. Still, it’s always fun to discover fascinating facts about things that seem very ordinary.

Scientists can explain the difference between good mould and bad mould, but all we see is a fungus that makes us reach for the bleach. The stuff can actually save lives. It can also seem like something out of a scary movie. Let’s dig a little deeper into nine amazing myths and facts about mould.

1. Even the Cleanest House Hides Mould

The idea that a clean house can grow no mould is just a myth. Mould spores are a natural part of our environment. They’re always present even inside the cleanest homes.

2. Some of the Stuff Is Good for You

Is mould really that bad? Mycologists who study the world of fungi are the first to point out that the world owes a great deal of its good health to the Penicillium mould.

3. It Can Help Your Garden Grow

When you catch a musty fragrance on the breeze in your garden, that means good mould is doing its job. The fungus plays an invaluable role in organic decomposition that keeps garden soil healthy.

4. Some of It Is Very Bad for You

One of the more disturbing facts about mould is how it can affect your health. Not all household fungi are dangerous, but Stachybotrys chartarum deserves its reputation as a highly toxic mould.

5. It Really Can Ruin Your Walls

Mould is a microorganism that constantly multiplies to live. It’s that evolutionary drive that allows the fungus to quickly spread through sheetrock and permanently damage materials.

6. Mould Is Actually Very Colourful

Most household moulds show up as dark splotches, but the unhealthy stuff can present itself in a wide range of colours. Orange, green and even white mould can make itself at home in your home.

7. It Has to Have Moisture to Live

Mould loves a damp environment especially in dark, hidden spaces. A good way to discourage the fungus is to keep your home’s interior humidity between 30 and 40 percent.

8. Mould and Mildew Aren’t the Same Thing

This is one of those mould facts that always needs clearing up. Mould and mildew are related, but they’re not the same. Mildew only grows on surfaces, and it’s easier to eliminate than its fungal cousin.

9. Mould Is Just One in 200,000

Mould stands out as just one of more than 200,000 fungal species. That number becomes much more impressive when you consider there are more than 100,000 individual species of mould.
