The house fly 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 back. House flies are attracted to decaying organic matter, food, and waste, making them frequent visitors in homes and farms. House flies have a short life cycle, usually living for about 15 to 30 days. They reproduce quickly, laying hundreds of eggs that hatch into larvae, commonly known as maggots. Due to their feeding habits, house flies can carry and spread diseases, making them a concern for public health.
