Acetic acid most likely kills all the spores but not as fast a solution as 
the bleach.

We simply use the same solution we use on extracting equipment before 
extracting. A very light solution and most likely does not kill all the 
spores but from my experience kills enough the next bees can handle nosema.

In fact a bee inspector told me years ago to use the same solution on stored 
brood comb if moldy when pulled from winter storage. In certain years these 
ocean containers *sweat* condensation and a white mold can appear on the top 
of stored pallets. A light spray of bleach solution quickly kills the mold.

I like the simple solution. Using acetic acid means stacking boxes up and 
sealing all holes. Placing the acid and waiting until evaporated ( a week? 
10 days).

I sold pallets of drawn comb this spring which had been bleach treated and 
the only complaint is his bees can not seem to get enough syrup. He hauled 
his bees to Texas last week and had to feed again as the bees were light.

A better problem than "my bees ignore syrup or are drowning in the feeders"

Dr. Eric Mussen says (based on his research) the bees jump in the feeders 
because the bees are actually starving due to the mid gut problem ( nosema?) 
and are trying to take in syrup.
Dr. Mussen and the maker of fumigillin say the bees can actually take syrup 
in when drenched as they groom each other.

I think bleaching the comb and replacing with healthy bees works best for 
me.
