I've got a few colonies on old comb that I'm intending to change this year. For a few frames I've used scorching before, but I just didn't fancy having to do 20-30+ frames using scrape and scorch if I didn't have to, especially as one colony in particular has a lot of chalk brood which I'm keen to make sure doesn't get recycled back into another colony down the line.

don't really like the idea of losing that wax, but perhaps with combs containing brood the best option is to just bag and bin them?
