It is natural for most of us to consider the housefly a nuisance. It annoys us with its buzzing sounds and when it crawls on our food and our skin. For ages, that is what man has considered the fly is a complete and utter nuisance.
However, it was not until the twentieth century that the innocent-looking housefly was discovered to be one of mans worst enemies. It was proven that flies actually carry disease and germs that could prove fatal to millions of people.
How does the fly carries the germs around? The fly's body, claws and feet are covered with bristling hairs. The tongue of a fly coated with a sort of glue. This means it will pick up things that sticks to its body.
The legs of the fly also secrete a liquid that helps it walk on walls. The body is so light that it can hang upside down from a ceiling just by the surface tension of the liquid secreted from its legs.
Flies are among the oldest insects known. There is evidence of fossil remains of flies, proving that they have been around for million years. For prevent this insect we should be very sanitary all over the world! Protecting food from flies is an important task in every kitchen.
