First 3 Jeju Island raids

The reason is because in the past raids Korea had to fight it alone, but now since Japan joined and their hunters acted as a bait to pull most of the ants out of the nest it was easier to go inside and kill the queen.
So it was for example 5-7 Korean hunters against all the ants that's why it was impossible

Hi guys anime only here. I just wondered how did they fail to kill all the ants in the first three raids? In the newest episode the ants weren‘t the biggest threat for the S-Rank hunters besides Beru but he is an exception and wasn’t there during the first three raids and I think the japanese S-Rank hunters aren’t that important for the fourth raid. So is there any explanation in the manhwa what happened during the three raids or did I miss some information in the anime?
