That's one way. I try to have drawn comb for the bees from a slimed hive, I've only had one, and put the bees & queen in a fresh hive. Then I freeze the comb for 3 days. AfteriI remove it I let it thaw out and then I rinse off the watery slime and put the comb on a strong hive which cleaned it up & was able to use the resources that were still OK.
This was told to me by the bee inspector. The hive cleaned out the dead SHB larvae and the disgusting comb was like new again.
BTW the fermented pollenfrom a slimed comb is the ultultimate bait if you ever use the beetle jail traps that have a center section for bait.
