If the first stage is not performed, and an attempt is made to kill ants on contact, the queen and some drones hidden deep with the nest will make a quick escape only to establish another colony at a new site, leading to a scenario of "the more are killed, the more there are."
如果不經第一階段，直接觸殺，往往在灌注過程中，躲在巢中深處的蟻后和部分工蟻就會迅速逃離另築新巢而「越滅越多」。吳文哲表示，二階段法較適合小面積如學校等人口密集的地方。
