The housefly is one of the most common species of flies in our homes. It evolved in the Middle East during the Cenozoic Era and spread throughout the world. Houseflies are not aggressive and will remain in your house for as long as they need to survive. However, they can be quite a nuisance if you let them in your house for long periods of time.
The average fly has a lifespan of 15 to 30 days. In this time, flies go through four stages in their life cycle. The first stage of the life cycle involves the formation of fly eggs. These eggs are laid by female flies after mating. Once fertilized, the female flies lay the eggs in warm, moist places. The eggs hatch in eight to twenty hours.
The lifespan of a fly depends on where it lives. Flies that live in cooler places live longer, while those living in warmer areas breed more quickly. Houseflies, for example, lay an average of 500 eggs in their lifetime. They also look for dead animals and trash to lay their eggs in. If you notice any signs of flies in your home, it is important to contact a professional pest control specialist as soon as possible.
While most flies stay within a radius of two miles of their origin, some flies are capable of traveling up to twenty miles.
