I did consider Rhino (the name of that ant) before going through all my explanation. I don't know why I took her word for it but I truly believe that her skin is almost indestructible to the point where only a specialized nen ability can cause harm to her. Rhino said his entire body was covered with hardened skin, true enough. But zazan claimed that hers had no weaknesses, as proven by even Feitan's ko unable to even scratch it. But anyway, I think I'll give it to Killua since there's a hint of proof that it's doable.
