[NHCOLL-L:4525] RE: freezers for killing cigarette beetles

[Anderson, Gretchen]

Generally speaking the -34 deg C should more than enough - I generally
recommend - 20 deg C with no defrost cycle..(based on Tom Strang's work
at CCI)   Also, go to the Museum Pests web site:
http://www.museumpests.net -- There should be a fact sheet are fact
sheets up on most of the museum pests, and there may be the results of a
survey recommending freezers that was done earlier this year posted.

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


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!
