I'm not talking about smoking the WHOLE hive, just having the pipe in your mouth, with a little smoke to keep the bees off your head and face. I would think the costs of using pipe tobacco to smoke your hive(s) would be a little excessive. And yes, I searched. Couple of threads from last year about chewing gum. And yes, I know that all human breath has carbon dioxide and bees don't like it. If some of you will watch the videos about German Skeff (sp?) beekeepers you will understand what I am asking, but I really just want to know personal experiences smoking a pipe and working hives. I like the "dizzy mite" story--cool.
