I think there's more to question #1. Take note that Kite and the team had to travel from wherever location the're at to NGL. It's implying that there are more than one group of chimera ants that can emerge elsewhere. The answer is that the Hunter association is quarantining them. Although the assoc can't be everywhere so there's the possibility of them re-emerging but not to the point where they will reach a king's birth because in the HxH world, there are probably not too many places where they can just eat people in thousands without drawing attention to their species.
