Why do flies like to land on humans?

Flies have very soft mouths and a lot of flesh, similar to sea foam. When they land on you and touch your skin, they do not bite but instead feed on secretions on the skin. They are attracted to sweat, proteins, carbohydrates, salts, sugars, and other chemicals, as well as the continuous shedding of dead skin cells in the human body.

Therefore, it is essential to control and prevent flies to protect our health.

Methods of preventing fly-borne diseases

Pathogens from spoiled food, feces, dead animals, etc., cling to the legs and around the mouth of flies. When they land on human skin, they transmit bacteria and viruses that can cause diseases. To prevent the spread of fly-borne pathogens, you need to:
