Has my child got asthma?

12) Dust mites

This wee sleekit beastie hides in every house, school and cinema in fact it is almost impossible to avoid. It feeds on shed human skin cells.

Allergy to the dust mite causes asthma symptoms.

Unfortunately, measures to try and get rid of house dust mites in the home are not effective.

Although there are  chemicals,  mattress covers, special allergy vacuum cleaners, freezing of soft toys, air-filters or ionisers they can be expensive and so far there is no research evidence to say that they work.
