Dust mites are microscopic insects which feed on human skin flakes. They are often the cause for asthma, allergic symptoms and some eczema because they produce proteases, an enzyme that is strongly allergenic.

House dust mites are insects with a tiny size of 0.3mm. Humidity is an important factor contributing to their growth and while the same holds true for temperatures, dust mites do not like sunlight and their number decreases in summer. It takes about a month until a mite has developed from a newly laid egg and adults have an average lifespan of two to four months, with grown-up females producing as many as 100 eggs in that time.

Since dust mites feed on dead skin cells which people constantly shed, it is almost impossible to avoid their presence in your home. However, there are ways to reduce their count. Dust mites are usually found in places where human skin flakes are most likely to turn up - mattresses, pillows, carpets, bedcovers, upholstered furniture, clothes, fabric-covered items, stuffed toys and fabric. Their population may vary throughout your house depending on ventilation, humidity, temperature and food source.

Usually, taking a set of measures is the most advisable way of dealing with dust mites infestations round your house. Airing out rooms and regular hoovering of your carpets will definitely contribute to solving the issue. Wash your bedding (including sheets, bedcovers, and blankets) once a week using hot water and try to reduce the humidity in your home. Use a damp cloth to remove dust regularly. What also helps is washing stuffed toys, vacuuming and steam cleaning carpets.
