The big winged bugs in the toilet flew into the nose and disappeared, will it be contagious?

It's not like a bee, it could be some kind of fly. Just clean it up.

You can try mosquito repellent for a fee. It has a certain effect on insects in both dark and damp parts of the home. If this does not work, then only the pesticide "insecticide" can be used.

The air is too humid, the toilet should be ventilated normally, kept dry, and the water on the toilet floor should not accumulate, otherwise it will provide an environment for spawning.

Let's live in a different place, the sun is not sufficient, and it is the easiest to breed insects, I hope you will adopt it!

In summer, open toilets in rural areas are often littered with maggots. This maggot is actually hatched from the eggs laid by the fly in the manure pit, and is the larva of the fly, which will transform into a pupal after a period of time, and then become a fly.
