For what purpose are you wanting to disinfect the wax? If it is for candles or even lip balm it is out of the hives and not going to infect colonies. If you are using it for the bees themselves, they won't care if it was discolored when disinfecting it. I wouldn't personally trust any disinfecting anyway. I scorch boxes, bottoms and lids thoroughly and doubt they are a concern but frames and combs are no longer on the bees.
What are your bee inspectors telling you to do to prevent picking up the outbreak? After supers are pulled and put away I would consider a course of treatment with tylan or tylox. For Goodness sake do not set your wet supers out to get robbed out! Fastest way to bring diseased bees into your apiary and to spread any infection you may have. It is tough. I burned two more hives this spring and two last fall and thirty the year before. I have inspected for disease everytime I pull a lid and have seen no indicators but I did treat with tylan early in the spring.
The wax would be repressed into new sheets of foundation!
I would have been under the impression that the wax was ruined by the treatment process and the bees wouldn't go near it! (my own thoughts)
Of course, I'm not going to do open feeding or another stupid way of getting any disease.
I don't feel at imminent risk of getting AFB, I want to recycle wax and want to clean it of any possible spores!
The Bee Association has a "lock down" on bees in and out of west Cavan.
(well asked all members not the transport bees in or out)
and its rural enough so they shouldn't spread naturally anyway.
(Thanks varroa destructor for killing the wild bee population!)
