Sterilising Combs

[The Drone Ranger]

This year I have most all of my unused boxes etc outside in the cold over the winter stacked to look like hives
Do you chaps use the black nails that Thorne's sell all the heads on mine disappeared as black rust
And as you say Jon the exposed frame wires disintegrated
I didn't realise it could kill viruses so that's a plus Gavin
I don't think its much use on chalkbrood from personal experience though
I think it is nosema it can dispose of in a short time right enough

Randy Oliver thinks
"Note: The above study has important implications to beekeepers. What is tells you is that in most of the U.S., winter freezing should be enough to kill most of the spores of N. ceranae! This supports the observation of a number of commercial beekeepers that letting deadout equipment “rest” for a month at cold temperatures resulted in better colonies when restocked in the spring."

He might be wrong but I though "why not"

By the by this is Randy Oliver again but I'm sure other people have said the same about nosema
"In warm weather the fumes from 60% acid will kill spores within a few hours; stronger acid will kill them in minutes!"
