Dermatophagoides spp house dust mites were found to be prevalent in geriatric nursing homes in southwestern Ohio. Mite density was lower in nursing homes than in private homes in comparable dust-sampling areas and at similar times of the year. Generally, fewer mattresses, floors, and articles of furniture were mite positive in nursing homes by comparison to private homes. Lower institutional mite levels were attributed to frequent linen and mattress cover changes and rigorous cleaning practices, coupled with the lack of a favorable mite environment provided by high ambient temperatures, low relative humidity, tiled or vinyl-covered floors and furniture, and covered or encased mattresses.
研究发现，俄亥俄州西南部的老年疗养院中普遍存在粉尘螨属屋尘螨。在一年中相同的时间以及可比的粉尘采样区域，疗养院中的螨虫密度低于私人住宅。总体而言，与私人住宅相比，疗养院中螨虫呈阳性的床垫、地板和家具物品较少。疗养院中螨虫水平较低归因于经常更换床单和床垫套以及严格的清洁措施，再加上缺乏高温、低相对湿度、瓷砖或乙烯基覆盖的地板和家具以及有套子或封套的床垫所提供的适宜螨虫生存的环境。
