Question 1

At what temperature do dust mites die?

Accepted Answer

Above approximately 55–60 °C: washing at 60 °C kills almost all dust mites in bedding [13]. Conversely, freezing at -18 °C kills most, but not all, of the eggs.

Question 2

Can you see dust mites with the naked eye?

Accepted Answer

No. House dust mites are microscopic; they measure between 0.2 and 0.4 mm.

Question 3

Do dust mites only live in beds?

Accepted Answer

No. Although they are mainly found in bedding, they are also found in sofas, armchairs, rugs, carpets, soft toys and other textiles.

Question 4

Do dust mites disappear in winter?

Accepted Answer

No. However, their numbers may decline when the air becomes colder and drier. Heating and indoor humidity provide favourable conditions for them.

Question 5

Is it possible to have a home that is completely free of dust mites?

Accepted Answer

In practice, no. The aim is rather to limit their proliferation and exposure to allergens by washing bedding, vacuuming, airing rooms and controlling humidity.
