The Bureau of Meteorology has declared a third La Niña is officially underway in Australia, with the event expected to peak during spring and return to normality early in 2023. With the chances of above-average rainfall and the potential for floods, it is important to be prepared for an increased mould risk.

Mould thrives in wet and humid environments, especially with poor ventilation. Its signs can start showing within 24 to 72 hours of a property’s exposure to water and moisture. With flooding and heavy rains possibly on their way, ceilings, roofs, and walls could become saturated, causing an outbreak.

How can you prevent mould?

Firstly, it is essential to remember that normal mould levels are naturally present in any ecosystem, but these levels can increase when excessive water and moisture are present. Australia experienced unprecedented rain during 2021-22, and those soggy days are far from over, creating the perfect environment for mould to thrive in.

Ventilation is the key when it comes to stopping mould, but only if humidity is under control. This means it is best to use dehumidifiers and air movers if possible. Windows and doors should be kept closed as much as possible, to avoid rain and humidity from getting indoors.

Unfortunately, ventilation will not always prevent the spread of mould, mainly if floods occur and the property is exposed to excessive moisture for days.
