Ants with wings

These days, in my room, there are lots of ants with wings.
I do not like that .
It is not because my room is not clean but becasue near my room there is a nest of ants, I guess.

I heard that they are male ants and only be to produce the sperms therefore they do not eat at all in their life.
Their way of living feaks me out completely.
I think they are not supposed to be in my room becasue they have a clear purpose and they do not have much time.
