I had a thought and I wanted to put it out on the forum for feedback:
I find working TBHs to be slow going because I'm taking great care not to crush bees as I close up the bars. I haven't used smoke and I really don't want to depend on doing so. I have tried Phil Chadler's idea (Biobees.com) of some cider vinegar diluted in water in a spray bottle. It works but not effectively enough. So I started thinking about an idea to put a little Bee Quick on a cotton ball inside a small bottle and giving the bees between the bars a whiff to get them to go down inside. Has anyone tried this? I don't want to order the stuff before I get some of your opinions.
