For those who have used this method to sterilize comb, I've read the instructions on some of the UK sites, but wonder: how strong is the vinegar smell? Can one perform the procedure in a garage or shed, or does one need to fumigate somewhere out on the back forty? What about the two weeks needed to air out the frames? As glacial acetic acid freezes at something like 65 degrees, what about ambient air temperature ranges during the fumigation?

What I have read called for diluting the acid to 80% if I recall correctly. Then it stays in a liquid state. The viniger smell is very strong and I personally have only done it outside.....oh yes I did do it once in a closed shed and I had to hold my breath to enter it!

I've never used it to fumigate, but I have used it many times in a laboratory. The smell is very, very strong. Many people find the smell objectionable, and at high concentrations you can expect mucous membranes (lungs, throat, nose, eyes) to be affected.

Once exposed to the air, the glacial acetic acid will rapidly absorb water from the air. I would not expect freezing to be an issue.
