Black mould will become a more common sight in households across the UK as temperatures drop this winter.
Mould thrives in places with high moisture levels, which is more likely when homes aren't well ventilated. The mould is known as stachybotrys chartarum and is a direct consequence of condensation, which is when hot, moist air meets cold, dry air.
Black mould bad can be bad for your home, but it can also harm your health. The NHS warns that if you have damp and mould at home, you're more likely to have respiratory problems and infections and sneezing, a runny nose, red eyes and skin rash - as The Daily Record reports.
