Exposure to ordinary air will control wax moth -- at least some
types for sure -- there are several.  The larvae require a closed
(warm & moist?) environment to develop in any numbers.
 
I do not know, however if eggs are affected, only that an infestation
cannot get going successfully if the supers are well ventillated.
 
In some warm areas (Greece -- if memory serves) some beekeepers hang
their combs in racks to ensure air circulation to protect them.
 
We disscussed this on this list sometime back in detail.
Unfortunately serching for this is difficult.
 
Co2 was not mentioned in that discussion, however.
