The concentration of house-dust mites (Dermatophagoides spp.) was investigated for four seasons in three locations in each of 50 Danish apartments. Simultaneously the absolute humidity was recorded and the previously known correlation between mite counts and indoor humidity was confirmed. It appeared, however, that apartments which had a low absolute indoor humidity in the winter period (due to low household load of water vapour) did not contain noticeable concentrations of house-dust mites in the summer and autumn despite the fact that the indoor absolute humidity in these apartments could be high enough to allow for a high peak-population of mites. Because of this it is suggested that in a temperate climate avoidance measures against house-dust mites should be supplemented at least by a drying out period in the winter, when this process is convenient to perform because of the low outdoor absolute humidity.
在丹麦的50套公寓中，对三个地点的室内尘螨（粉尘螨属）浓度进行了四季调查。同时记录了绝对湿度，并证实了螨数量与室内湿度之间已知的相关性。然而，在冬季室内绝对湿度较低的公寓（由于水汽的家庭负荷较低），尽管这些公寓夏季和秋季的室内绝对湿度可能高到足以形成螨虫的高种群峰值，但并未发现明显浓度的室内尘螨。因此，建议在温带气候中，针对室内尘螨的预防措施至少应在冬季增加一个干燥期，因为此时由于室外绝对湿度较低，进行此过程较为方便。
