Beepro, I like ed?s Idea of feeding sugar syrup instead of foreign honey. AFB is rather unique in the bacteria produced spores. As Jim stated boiling does not kill spores.
To kill spores one has to heat to 131 degrees centigrade with 25 psi for 20 minutes. The time is the only variable. That is the definition of sterile, again: 131C at 25 psi. Spores, virus particles, all life is destroyed at those conditions. There is one exception: Prions the agent of mad cow disease, Kuru, spongiform encephalopathy, proteinaceous infection particles, are all the same thing and the agent is NOT destroyed by 131C and 25 PSI. Just pointing out an exception, there is no such worry with Honey.
Honey from your own apiary would cause me no real alarm. Read about honey from China and you will be horrified. Last year in 2017, in Chicago, approx 17 tons of Chinese contaminated honey was seized by custom agents.
Honey is basically glucose and fructose with pollen and precious enzymes. Table sugar is also fructose and glucose, 100%. There are specialized honey such as Acacia and Tupelo that have high fructose levels, 70% thus they rarely crystallize. Just pointing out all Honey is not the same.
In short, sugar is not bad, it?s just fructose and glucose as the digested sugars, the exact same fructose and glucose in flowers. There is no difference in the sugars. Flowers also contain other products but I don?t wish to redirect this subject anymore than I already have.
So feed sugar syrup, it?s s lot safer than foreigh honey.
