How are Flies Born?

We all know that flies carry disease. The fly is born and may spend most of its life around rubbish and germ-breeding areas. The housefly actually chooses moist decaying matter as a place to breed.

The female lays the eggs, which are white and about 1.2 millimeters long. From each egg comes a slender, worm like maggot. This is the feeding stage, or “larva”, of the fly.

After five or six days, the maggot’s  skin thickens and becomes brownish. This begins “the pupal”, or resting, stage . Five or six days later, the full-grown fly bursts out of the pupal skin.


The fly is then as big as it will ever be, for big flies do not grow from small flies. About ten days later, the fly mates, and soon after the female lays from 100 to 150 eggs! Not all flies breed like the housefly.

Many kinds hatch their eggs in their bodies, giving birth to living larvae. Some kinds lay eggs that are already at the pupal stage.

Man is waging a constant battle against the fly because it spreads disease germs. During tha cold weather, the fly hides away in dark, warm corners of buildings. When flies are seen during the winter in well-heated buildings, they should be killed. At that time, flies are easy to catch because they are very hungry.
