This post is mainly for me so that I can find this info again if I need it. A couple of weeks ago, Solomon Parker, a podcaster who interviews treatment-free beeks, started an interactive Google map of treatment-free bee-suppliers. Not all of these suppliers sell packages or TBH nucs. However, it's always nice to know where to get a queen or maybe work out a deal with someone who might try doing a nuc for you.
New suppliers are always being added, so don't be discouraged if you don't see one near you right now. Also, if you know of one not on this list, you could let him know. Solomon moderates the Treatment-Free Beekeeping group on FaceBook.
