Laboratory test show an optimal development of a house-dust allergen generating mite, Dermatophagoides pteronyssinus (Trouessart) at a temperature of 25° C; after 8 weeks at a temperature of 30° the number of mites is 40% of the number at 25°, at 20° only 15%. In the Dutch climate only in summer is relative humidity in houses high enough to allow rapid population growth, but the average temperature on floors in summer is usually below 20°. In occupied beds and upholstered chairs temperatures increase in a short time to optimal levels for mite breeding, and relative humidity increases by 5–8%. It is to be expected that in summer beds and chairs are suitable breeding places in a temperate climate.
