His presence has two assumptions, bad or good

^{What you know about flies, of course, there are many things that can be seen from everything they have, both character and the impact of their presence in an object of their choice.}

^{In essence, everyone does not want his presence in all situations, assuming his presence, to be a bad thing for human life.}

^{(¬Musca domestic or house fly ®2022¬)}

However, not all evil comes from the fly itself, sometimes it has an important thing for everything that humans are unable to do or are reluctant to do, namely something bad like garbage or the like in a certain location.

With the intention that flies are also important in human life, namely in accelerating the decomposition of waste into soil such as compost and others.

There are several species of flies that are still in the same Order capable of carrying out a natural process by proving it at the garbage location itself. So with a fair assessment it can be said that, the fly becomes bad when it is in an object that is protected by humans but will look good when it works as a waste decomposer.

^{Then how about this one fly?}

These flies also often visit organic waste, the waste will be used for breeding, in general they only mate once in their life, according to field observations it varies, but is often seen for 28 days at a certain temperature, and some house flies have an age of about 1 month, you can find out about this in an explanation at this link ^resources

When the female fly finishes mating or after being fertilized, she will store the male sperm in her body and when it's time to lay eggs, the female will look for organic waste from carcasses and food scraps. Then the organic material will be used to lay eggs in large quantities or about 100 units, the organic material will automatically decompose along with the development of the birth process and you will see small white larvae without legs, our residents here say they are maggots that live and breed in organic matter.

Thus, it can be assumed that there will be a beneficial presence, for the environment, in removing traces of waste in the removal mechanism that accumulates naturally. Although it is said to be a decomposition process in removing the buildup of garbage.

It looks like their presence is a bad thing but there are also things that are beneficial for an environment, those who make bad things and those who disappear bad things in an environment.

Indirectly, the existence of this fly has tied a relationship that reaps a vision, meaning that some say its existence in an environment is very bad and some say its existence has also disappeared, a bad thing as described above.

If the explanation above mentions several benefits, then what are these bad behaviors?

In this regard, everyone understands this behavior, because it is often active in our homes. They often seek and always look for any food object, no exception as long as there is a certain object. In general, he will continue to stalk every smell of food whether the food is fresh or stale.

If he lands on food that has rotted it is not a problem for humans, and the bad thing is that he lands on fresh food that has not gone stale.

The danger is when they are in fresh food, because it brings something dirty, because each of them must have just finished standing on a bad object in the form of :

1. Every carcass that has rotted
2. In every animal and human waste
3. and, on every dirty object that has the potential for bad bacteria and bad viruses.

Dirty objects, which may be bad bacteria and viruses, become a condition that humans do not like because they can make a healthy body sick, of course the origin comes from the spread of a fly that has just finished from the dirty object. The transfer of bad bacteria and viruses occurs automatically which attaches to the downy hair.

Not to mention when they are on top of the food object, chronologically when they are busy eating food, they will also automatically vomit food in their stomach against the food itself, well this is where the bad spread of bad bacteria and viruses lies. This spread can be said to come from two points, namely from external objects and from the body. If you look closely, it turns out that these two objects are equally useless for humans because if the food that has been infested, then consumed again can make a person sick, due to contamination by accidental spread.

*Conclusion

The presence of flies in every human environment reaps two assumptions, namely :

1. Beneficial for an environment in breaking down organic waste
2. The spread of bad bacteria and viruses that are not good for the health of the human body.

Therefore, live clean, do not pile up garbage, throw garbage in its place, and cover food tightly, so that flies cannot penetrate it. When we do these characters together, we see that all will continue to be healthy forever.
