I have never seen denatured alcohol for sale in Ontario, only isopropyl alcohol but it is the alcohol of choice for disinfecting purposes etc. in Poland and I know now in France, too. Maybe all over Europe? As for the corn vodka...Any respectful vodka is made from rye grain or potatoes, so I am not surprised. Moonshine would be even cheaper , I suppose. Lastly, thank you Leo. I thought it might be the case. I feel much better now! The mealy bugs are driving me crazy in my cozy sunroom in the depth of our never ending Canadian winter as well. Not in my cool greenhouse. Too cold for them I suppose. Bea --- This email is free from viruses and malware because avast! Antivirus protection is active. http://www.avast.com/
