ofcourse, my messor queens, all 3 of them can kill easily, infact they are more aggressive than the workers when you put food near the Queen.
i put in a moth once and she jumped on it and killed it in 2-3 seconds by just clamping her mandibles near its head ! that was great to watch, like a lion choking a wildabeast when its crushing its wind pipe.....gosh i sound like a right morbid guy.....im not.... lol
(and once i fed A Sweetener to my Apheaonagaster and it killed the queen. but if its pure sugar, no problemo)
Merry CRIMBO !
