Is it needed that the brood be actually killed? From somewhere I have the idea that someone just pricked the cappings open in a triangular pattern, 7 on a side. Don't the bees remove any larvae that have been disturbed this way? I always assumed when I was ready to do this I'd make a tool with about 50 needles in it (You figure out how many) and just stab the helpless little guys.
