Experts say remaining moisture and humidity levels in south-east Queensland have created the perfect breeding ground for mould, which can pose a significant health threat.
The warning comes as dozens of areas across the state are still recovering from devastating floods earlier this year.
Mould can lead to ongoing respiratory issues and symptoms of fatigue and the flu.
Experts are urging people to check their homes for any small growths of mould to try to prevent further growth of the fungi.
It is best to look around and in cupboards, behind couches, behind bed heads, as well as outside the home.
Experts advise residents to maintain as much airflow through their properties as possible following wet weather events and to eliminate any pools of water in a bid to prevent mould.
Ceiling and pedestal fans are also recommended to maintain airflow and residents with damp problems are encouraged to leave windows open, particularly in bathrooms and laundries.
