The whole life cycle from laying of the eggs to adults dying off of old age takes place in 3-4 weeks total with the range changing depending on the local temperature. There may be several generations during the summer but these insects usually disappear with the onset of dry weather. These eggs hatch in 2 to 3 days.

With indoor infestations there will typically be continuous reproduction and overlapping generations with all life stages likely to be found. What about the fungus gnats life cycle.
