Are these thrips? How do you get rid of them?

Hi Gardeners!

I need your advice! I am plagued by these tiny bugs. They are everywhere around the flat. They come in through the windows and the balcony and hang around the walls and the ceiling. They can fly and notoriously land on people, which is very annoying.

I suspect that these are thrips, but I am no expert and would like confirmation. If these are thrips, then I do not understand why they are here, because there are no plants around. Neither inside nor on the balcony.

What can I do to get rid of them? How can I prevent them from coming inside? Reminder: They are inside, so I would not like to spray insecticide around.

Thanks in advance!
