Will the bathroom exhaust fan get into the small flying insects?

Yes, it is best to install a reverse device to block the entry of small flying insects.

The general exhaust fan has a check valve, no need to buy separately, small flying insects will not fly in, mainly to prevent the outside turbidity, moisture, outdoor air backfilling.

If there is no baffle for the sanitary napkin exhaust fan, it will definitely enter the small flying insects. However, the sewer pipes in the bathroom itself can breed small flying insects. Therefore, we must do a good job of toilet hygiene and smooth running water.

Can bathroom exhaust fans fly into bugs? If the exhaust fan is on, it can't fly, because the wind is pumping out, that is, when the exhaust is not exhausting, the outside baffles will fall down one by one. It is possible that small flying insects will burrow into small gaps.

However, you can spray the baffle on the outside of the exhaust fan every once in a while, and the radar may work.

The exhaust fan in the bathroom can enter the small flying insects, because the exhaust fan in the bathroom is also very large. So relatively small flying insects can fly inside.

This problem depends on the installation of the exhaust fan, if there is a dense net outside the exhaust fan, there will be no small insects coming in. Otherwise, there is a risk of getting small bugs.

It should be a gnat, mainly breeding in the corner of the bathroom or kitchen at home, tile gaps, sewers, and under the pallet where objects are placed.

Should I read the content of the class to the teacher after CC English? Your question is too general, to know what level you are at. For example, if you are at the level of level 4 or 6 in a normal university, study abroad, and foreign teachers are like singing rap in class, and you have a bunch of specializations.

I think it's entirely possible.
