Hi Bob,
 
I'd also be interested in the answer, as I had some of it last summer too.  My guess is they're probably pretty well protected from freezing temps below ground.  If you find an effective method to kill, maim, or disembody them, please let me know.

Last year I had a pretty bad infestation of RCB.
I have tried to find out what the cold tolerance of these critters is but have failed to find any info.

Does anyone know if the larvae freeze out and at what temperature?

Quite cold here at 6,000 ft in Utah.
