These thrive in damp conditions and can be commonly found in places like window fixtures, kitchen sinks, shower curtains and damp basements.

Many allergy sufferers are allergic to mould spores as well as pollen without realising there's a difference between the two. Although staying indoors can often mean you avoid pollen to a certain extent, it's not so simple with mould spores. Mould can grow anywhere that has the right conditions indoors, such as bathrooms. You can find moulds outside on compost heaps, in soil, rotting wood and grass cuttings.

Coping with mould spores

If a member of your family suffers from an allergy to mould spores, there are some simple things you can do to help them to control their symptoms and find relief. For example, try to keep damp areas such as bathrooms well-ventilated and clean using anti-mould cleaning products.
