======================================================
nejsofistikovanější postup z výše uvedených zdrojů říká:

Check the hive for sac brood once every two weeks. If sac brood is present, take the following actions.

* If the attack affects than 20% of the comb, remove the comb and burn it, or melt it in a Solar Wax Extractor.
* If more than 20% of the brood is infected, all adult bees must be destroyed with a household aerosol pesticide spray. To ensure all bees are dead, close the hive and spray it again after 24 hours.
* Separate the comb wax from its frame, and burn or melt the wax.
* The hive's frame should be fumigated with formalin. This can be done by putting the frame in a plastic bag together with a small cotton roll soaked with 40% formalin. Close the end of the plastic bag and leave it for 24 hours
* Isolate the hive box and sanitate it before reuse. Either fumigate it with formalin, or submerge it in 2% Clorox or Dettol solution.
* In a situation where 5-20% of the brood is infected, the colony can be helped to recover replacing the queen.
This may be either:
* Self recovery, where the colony produces a new queen.
* To old queen is removed from the hive, and a new, healthy and fertilized queen is introduced, 21
days later.
* Once the new queen is introduced, sugar syrup should be added to speed up the development of the
bee population.

In a situation where less than 5% of the brood in a hive is infected, two colonies from two hives can be
combined together. Sugar syrup as an additional food should be given to help the colony to recover rapidly.
===========================================================

jednodušší řešení navrhuje:

* Re-queening with a young vigorous queen.
* Strengthening any weakened hives by uniting with a disease free nucleus hive of young bees.
* Move bees to better conditions with a good honey flow.
* Feed bees a sugar solution and quality pollen if supplies are low.
* Pack the bees down into fewer boxes.
* Routine comb replacement.
