If you are wondering how house flies can be so fast, the answer is simple: their short life cycle. One female lays about 120 eggs at a time. This means that one pair of flies can produce as many as 191 billion house flies within five months.
They can achieve this speed by extending their legs and flying towards a surface. They also have sticky pads on their tarsal claws, which enable them to grip on nearly any surface. If they can reach a surface, it is easy for them to travel. House flies are also known for their wandering behavior, which enables them to scurry from place to place.
Flies use clever maneuvers when they are trying to avoid being squashed. They freeze when they sense a threat, and then quickly move their wings and legs to escape. Their ability to change direction in a split second allows them to precisely pinpoint the direction they need to travel to avoid harm.
Adult house flies can live for about fifteen to thirty days. This allows them to reproduce and lay eggs several times a day. The average female flies lay about five to six eggs during their lifetime, but they can lay as many as 150 in one month. These eggs are usually just 1.2 mm in length and can hatch in 12-24 hours in warm weather.
