Asthma triggers in your home

House-dust mites

90% of people with asthma say dust triggers their asthma. This is actually a reaction to the droppings of dust mites. Dust mites are tiny creatures that live in the dust that builds up in our homes – in carpets, bedding, soft furnishings and soft toys.

"Research tells us there’s not a lot we can do to make a useful difference to the number of dust mites in our homes," says Dr Samantha Walker, Asthma UK’s Research director. "You’d have to be doing everything we suggest here on a regular basis to achieve even a small drop in numbers. The best way to reduce asthma symptoms is to look after your asthma by taking your preventer inhaler as prescribed, and using an asthma action plan to help you work out if your symptoms are getting worse, and what to do about it if they are."

If you do want to try and reduce dust mites in your home here are some ideas:

  1. Allergy ‘barrier systems’ are designed to stop dust mites getting into your bedding. These are specially designed covers for your mattresses, pillows and duvets
  2. Vacuum regularly using a vacuum cleaner that sucks up dirt and dust really well and one that doesn’t scatter dust, preferably with a good filter system
  3. de-humidifier dries the air and makes it hard for dust mites to survive
