Answer 1

Answer:

House flies are such a common insect that it is considered part of everyday life for humans. Most of us see it as just an irritation, buzzing around and trying to feed on any food it can access within the home but flies can also transmit diseases. In fact many common infections are transmitted by house flies. Some diseases are very serious and even potentially deadly. Although it can never be eradicated entirely, reducing fly populations and limiting its contact with food in particular is an important part of hygiene.
