How Long to Common House Flies Live

The housefly is one of the most common types of flies in your home. They evolved in the Middle East during the Cenozoic Era, and have since spread to every corner of the world. In fact, this fly is so prevalent that it is considered the most common type of fly you’ll find in a house.

The typical life span of a housefly is between fifteen and thirty days, although they have been known to live up to 60 days. This short life span is due in part to the fact that these flies complete their life cycle quickly. Their eggs hatch within a few hours, and their newborns complete the larval stage within ten days.

Adult flies live between 15 and 25 days. However, they can live as long as two months if they are given suitable food. They also live longer in cooler temperatures. A good source of protein can help increase the lifespan of the fly. A female house fly can lay up to 3,000 eggs in her lifetime.

Adult house flies spend at least two weeks in larval form. They begin their lives as maggots. Maggots are brownish-red or dark-yellow, with rounded ends. Adult house flies are approximately two to four weeks old, and feed on softened and liquid materials.
