Fly Facts

  • During its lifespan a female fly can lay eggs five to six times, producing 750–900 eggs.
  • Two flies that mate can develop into a population of more than 191 billion flies.
  • Research indicates that flies are capable of transmitting at least 65 diseases to humans, including typhoid fever, cholera, leprosy, and tuberculosis.
  • Flies cost the U.S. dairy and beef industries nearly a billion dollars in annual production losses.
  • The life cycle of a fly typically spans between 2 weeks to 2 months and varies according to temperature:
    • 60°F: 45–51 days
    • 77°F: 14–16 days
    • 95°F: 8–10 days

The Life Cycle of the Fly 

There are four distinct stages in the in an average fly's life cycle:

  • Egg (8–24 Hours): Flies prefer to breed in damp, dark areas. Manure, compost, and areas with decomposing organic material are prime locations for egg laying. Depending on the size, a female house fly can lay up to 900 eggs in a three to four day period.
  • Larvae (4–7 Days): Larvae are commonly referred to as maggots. They emerge from the eggs and begin eating whatever they can find in the area where they were laid.
  • Pupa (10–20 Days): Maggots move to higher, drier ground to begin the the pupa stage of their life. They encase themselves in a reddish-brown skin where the final stage of development takes place.
  • Adult (14–30 Days): The adult flies hatch from the pupal stage and have an approximate life span of two weeks to one month. Females are able to start producing eggs after two days of life and will continue to lay eggs for about a month.
