I found out, that apparently there's another "trick" to kill the queen ant that's recently discovered. Supposedly you kill all the nurses together, and right afterwards bang all the larvae to keep their HP at 0, so only 2-3 nurses instead of the normal 8 respawns. Then you kill those 2 nurses ASAP, and go back banging on the larvae again. This process is indeed much easier said than done, since it still requires enormous damage dealt in a short period of time, but in comparison to kill the queen ant with all 8 nurses healing, infinitesimal.
