Moulds (also called mildew or fungi) are parasitic micro-organisms that appear as a black, white or multi-coloured stain or fuzz. Mould spores can cause asthma and other allergies. Some moulds also release complex chemicals into the air called mycotoxins that can cause serious health problems. There are tens of thousands of varieties of moulds, and identifying them is a difficult and expensive task, even for experts. Therefore, health officials recommend eliminating all moulds from inside your home.

Most mould spores need free water (in other words, condensation or damp materials) to germinate. However, once mould colonies are established, many generate their own moisture and can continue to survive even under dry conditions. Moulds also need mild temperatures and a source of food, such as house dust or drywall paper.
