I look at it this way. To make liquid smoke for the bees takes time. To buy it, you are going to blow over a buck a pack. I burn anything in my smoker that doesn't cost me. Right now, I start it up with packing paper that comes with the boxes through the mail. And to reload in the field, dry leaves, pine straw, paper, or even cardboard. Free stuff that don't take much time. With the smoke smell, in a couple of months, everything I own will have a slight smoke smell with winter coming on. :-D
