Urgent help identifying ants?

I don’t know what these ants are, but they are tiny, winged, and they jump. It’s urgent because they’re all over my niece’s bed and dresser. Can anyone help?

They were there the other night as well, but we cleaned everything and vacuumed the crap out of the mattress, so we thought we had it taken care of, but they’re back with a vengeance.

Can we take care of this ourselves or will this probably require and exterminator?
