Hi Mark,

No answers from Nafex...
I have read about the critters and it looks like the only way to get rid of them is to drench the crowns with insecticide.
I don't really want to do that and so will dig all the roots up early in the spring and do an insecticidal soak in some buckets before transplanting them to a new place.

If you can remember in the fall, I'll know for sure if it worked.

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.
