Has anyone observed the effectiveness of FGMO compared to using esential oils for the treatment of mites? There seems to be support for both methods, and I wondered about the pros and cons of each.
I haven't observed the effectiveness since I'm new to beekeeping. The fellow I buy bees from has used both and says they both seem effective, but he doesn't like the labor-intensive nature of using essential oils since he has so many hives. He likes the mineral oil, but has only used the method of putting beads along the top bars, and said that more bees are killed than he likes to see with this method. I don't believe he has tried the fogging and emulsion-soaked cords.
