I've been told that even liquid nitrogen doers not always kill the brood it
intended to.  Apparently, at some stages, brood is pretty tough.

There is an optimal stage in the development that should be chosen, too, and
this is one of the toughest stages to kill.

I'm hoping that Jerry, the inventor of this particular technique, will be
around to comment, too.

If not, a BEE-L archive search will dig up lots more details.
