Dustmite

House dustmites are microscopic spider-like creatures which live in beds, carpets and other soft furnishings. They are a common source of indoor air pollution.

The faeces, skin casts and pieces of dead mites contain substances which can trigger asthma attacks, inflammation on the lining of the nose and eczema in sensitive people. House dustmites are present in almost every home, although because they are so small you will be unlikely to see them. They tend to thrive in warm, humid conditions.

A dustmite problem can be alleviated by keeping the house and beds well aired, and ensuring that carpets are kept clean and dry. Regularly dusting and vacuuming of soft furnishings will also reduce the incidence of dustmite.
