[NHCOLL-L:4523] freezers for killing cigarette beetles

[Dallard at aol.com]

Hi,
 
We are planning to purchase a new chest freezer for our herbarium. We find  
that they are available in models that freeze to -34 deg. C or to -40 deg. 
C.  Does anybody know if the lower temperature is more effective at killing  
cigarette beetles, or if we can get by with the less expensive, -34 deg. C. 
 freezer?
 
thanks!
