Answer 2

Interesting question.  They must live longer than we think.  When I go up in the attic on a warm day in winter, they seem to come alive around the windows, sending me  into a frenzy with the Raid! So, I wonder if they don't go into some sort of hibernation and live from one season to the next?

Answer 3

Relatively short life span:  2-4 weeks.

Answer 4

100 years or it sure seems like it

Answer 5

Adults usually live 15 to 25 days, but may live up to two months. Without food, they survive only about two to three days. Longevity is enhanced by availability of suitable food, especially sugar. Access to animal manure does not lengthen adult life and they live longer at cooler temperatures. They require food before they will copulate, and copulation is completed in as few as two minutes or as long as 15 minutes. Oviposition commences four to 20 days after copulation. Female flies need access to suitable food (protein) to allow them to produce eggs, and manure alone is not adequate. The potential reproductive capacity of flies is tremendous, but fortunately can never be realized. Scientists have calculated that a pair of flies beginning reproduction in April may be progenitors, under optiminal conditions and if all were to live, of 191,010,000,000,000,000,000 flies by August.

The house fly has a complete metamorphosis with distinct egg, larva or maggot, pupal and adult stages. The house fly overwinters in either the larval or pupal stage under manure piles or in other protected locations. Warm summer conditions are generally optimum for the development of the house fly, and it can complete its life cycle in as little as seven to ten days. However, under suboptimal conditions the life cycle may require up to two months.
