Does anyone store comb in a freezer(quantity permitting)?
Nigel, I used to store my supers in my 'bee workshop' which is heated when I want to use it over winter. And moths can get in through an open door at night in a second - and then see if they can find some wax somewhere. It's easy to knock some boxes so the crown-board comes off a fraction of an inch and they're in.
For the first time last winter, a lot of my supers were stored in an unheated barn.
However, to answer Alfred's question, I put supers in an old chest freezer, 6 at a time, for 48 hours or more and then store them or cart them to the barn whilst frozen. They are stacked up with cardboard between every few boxes to limit the travel of a wax moth if it did happen to get in through a gap somewhere.
