An understanding of the life cycle of house-dust mites, as well as environmental factors influencing mite populations, can be exploited in mite control. The most important limiting factor for house-dust-mite populations is air humidity. House-dust mites osmoregulate through the cuticle and therefore require a high ambient air humidity to prevent excessive water loss. In addition, the supracoxal glands actively take up ambient water vapour, and the protonynph stage of the life cycle is resistant to desiccation. Larger house-dust-mite populations are found when the absolute indoor air humidity is above 7 g/kg (45% relative humidity at 20 degrees C). Consequently, ventilation by air-conditioning systems is being developed as a means of control. A number of other aspects of the domestic environment are also being manipulated in an integrated approach to render the habitat less suitable for mites. The potential exists for developing models for house-dust mite populations, environmental characteristics, and the effects of various approaches to control.
了解屋尘螨的生命周期以及影响螨类种群的环境因素，有助于螨类控制。屋尘螨种群最重要的限制因素是空气湿度。屋尘螨通过角质层进行渗透调节，因此需要较高的环境空气湿度以防止水分过度流失。此外，基节上腺会主动吸收环境中的水蒸气，且生命周期中的幼螨阶段对干燥具有抗性。当室内绝对空气湿度高于7克/千克（20摄氏度时相对湿度为45%）时，会发现屋尘螨种群数量更多。因此，空调系统通风正被开发为一种控制手段。家庭环境的许多其他方面也正在采用综合方法进行处理，以使栖息地对螨类不那么适宜。开发屋尘螨种群、环境特征以及各种控制方法效果的模型是有可能的。
