The average life cycle for a house dust mite is 65–100 days. [9] A mated female house dust mite can live up to 70 days, laying 60 to 100 eggs in the last five weeks of her life. In a 10-week life span, a house dust mite will produce approximately 2,000 fecal particles and an even larger number of partially digested enzyme-covered dust ...
Dust from surfaces such as floors, beds, or furniture is often collected to assess health effects from exposure in epidemiology studies. Researchers of indoor mold also use a long-term settled dust collection system where a dust cloth or a petri dish is left out in the environment for a set period of time, sometimes weeks. [ 18 ]

The representation is made on a temperature-relative humidity, instead of a standard psychrometric chart. The comfort zone in blue represents the 90% of acceptability, which means the conditions between -0.5 and +0.5 PMV, or PPD < 10%.
Dust is made of fine particles of solid matter. [1] On Earth, it generally consists of particles in the atmosphere that come from various sources such as soil lifted by wind (an aeolian process), volcanic eruptions, and pollution. Dust in homes is composed of about 20–50% dead skin cells. [2]
House dust mites, found in warm and humid places such as beds, cause several forms of allergic diseases, including hay fever, asthma and eczema, and are known to aggravate atopic dermatitis. [ 60 ] Among domestic animals , sheep are affected by the mite Psoroptes ovis which lives on the skin, causing hypersensitivity and inflammation. [ 61 ]
