As a 61 warlock it was pretty straightforward to solo grind my way to Natalia. The main problem was figuring out which tunnel system she was in since that hive has 3 and I couldn't seem to find the right entrance. (It's the tunnel entrance in the far south of the hive.)
I cleared the room with Natalia by single-pulling bugs into the adjoining hallway. Then I opened on Natalia with Fear and loaded her with DOTs.
As the fight progressed it was clear I would be able to finish her off before I ran out of mana or health. She was perhaps down to 50% when a bug repopped. This was the neutral bug that stands near Natalia. It had been the last bug in the room to die and I had killed it less than 30 seconds before attacking Natalia. The bug aggroed immediately upon respawning. Game over.
