The housefly is a common insect found worldwide, known scientifically as Musca domestica. It typically measures about 6 to 7 millimeters in length and has a grayish body with four dark stripes on its thorax. Houseflies are attracted to decaying organic matter, which they use for feeding and breeding. Houseflies have a short life cycle, usually living for about 15 to 30 days. They reproduce quickly, laying hundreds of eggs in suitable environments. While they play a role in decomposition, houseflies can also carry diseases, making them a concern in homes and food establishments.
