The harm of flies

The longest life span of flies is 15 days. If they don't get food for a long time, they will die soon. Therefore, taking good care of all food and disposing of garbage is a fatal blow to flies.

Flies can spread germs, especially when they stay on food, which is more dangerous. Although flies at home generally don't bite people, they can spread various diseases and germs, such as salmonella, malaria and tuberculosis.
