Hi All I was just thinking about this whole AFB and beehives with spores in the wood story. This may be a really stupid idea, but how would some agent like formaldehyde or glutaraldehyde (apart from the fact that they are poisonous and carcinogenic they are highly volatile) which would intercolate (basically gum up the workings) of most organisms in the wood?? Just a thought. I know it wipes out B.cereus and subtilus, don't know about the ones that cause fould brood though.
