How fast is the reproduction of house dust mites?
A female house dust mite lays up on 3 to 4 eggs a day during her life time of 120 to 160 days (at the average about 300 eggs at a life time). Grubs hatch out of the eggs and grow (including 2 skinnings) at ideal living conditions to adult male of female house dust mites. This takes about 30-40 days.
