Creating a healthy home can help you and your family breathe cleaner, fresher air and hopefully reduce allergic reactions or allergy-related asthma episodes.

First off, you need to know which allergic triggers affect your asthma, such as dust mites, pets, pollen and moulds. For help on how to identify triggers, see – Common triggers.

And then you can take steps to avoid or reduce the impact of those triggers, if possible.

Common triggers

The best way to avoid an allergic reaction is to avoid the trigger that causes it, but this is not always possible. However, reducing exposure to your allergy triggers may make your symptoms easier to manage.

Bear in mind that efforts to avoid or reduce allergy exposure can be costly, time-consuming or impractical, and may not work for every person or circumstance.

If you’re keen to try, the first step is to know what triggers your allergies so you can focus your efforts in the right area.

Dust mites

They like moderate temperatures and high humidity. They are found in bedding, flooring, window coverings and furniture. Their poo is the main culprit and is small enough to become airborne when stirred up.


Mould needs long periods of humidity to grow. Houses in tropical areas or with rising damp may be more at risk. Poor ventilation may mean a bathroom or built-in robe can produce mould, even if not in humid areas.


Cats and dogs are the most common cause of pet allergies. Guinea pigs, rabbits, birds, mice and rats can also trigger asthma or allergies in some people.


Trees, grasses and other wind-pollenated plants are the source of the most troublesome pollens. For many people, spring is the worst time, but some plants produce pollen in other months of the year.


Both cigarette and wood smoke can cause or worsen asthma symptoms.
