This is a list of possible candidates to kill pathogens etc
I started looking in response to this stuff on Paynes site
http://www.paynesbeefarm.co.uk/other...tion/bee-safe/

That one is based on iodine

If you read through the first article though you can see how few possibles there are to treat spores
Worse than that though is how spores in presence of biological material are even less easy to deal with
I assume that will apply to propolis and wax and old combs etc

Hydrogen peroxide might work ?

Has anybody else any ideas

I also read that high acidic concentrations might work
Eric McArthur suggested heavy feeding (presumably to get all the mummies thrown out)
in combination with formic acid treatment ( lowering the PH in the hive)

You can just burn the combs but a lot of beekeepers are uncomfortable with that solution being too drastic
