How House Flies Are Born
The process of how house flies are born begins with maggots, which are tiny white creatures that feed on decaying food. Maggots live in the larval stage for up to two days, and then enter the pupal stage, where they begin to develop legs and wings. Pupae also have a fluid-filled pouch in the head, which helps them break through the hard outer shell of the pupa. Once they emerge, the female flies can breed within hours.
The eggs of house flies are laid in filth, and the larvae develop into pupae around decaying things. If you notice that your house is infested with these critters, the first thing you should do is check your garbage disposal unit. It is likely that they have been attracted to the odor of garbage.
The eggs of house flies are laid on decayed organic matter such as food waste or carrion. The eggs are small and white, and hatch within eight to twenty hours, depending on the conditions. Once they have emerged from the pupal stage, they feed on the waste and grow into adult flies.
Houseflies reproduce in batches of 150 or more eggs. They prefer decomposing organic matter and dark surfaces for their egg laying. The legless larvae feed on these materials for three to five days. They then search for a dark place to pupate. Once they have grown, the pupae develop wings and legs and grow to become fully grown adult house flies. Adult female house flies live for about fifteen to twenty-five days, depending on the temperature.
