There are a lot of people who are intimidated by the amount of work and the complexity of a shake-down regression. I understand that because I'm doing it and it is a commitment of time and energy and stress on the bees.
I understand, do to your commitment to not use chemicals, why you recommend doing it in shake-downs so that it can be accomplished quickly. But for those who are not willing to do that, and intend to use alternate methods of mite control, don't you think they would benefit from simply using 4.9mm foundation? Eventually their bees would get regressed, especially if they culled brood comb in the spring when a lot of it is empty. With no real change in managment and no real commitment in time and energy they would eventually have a regressed hive, wouldn't they? Or am I missing something in my thinking.
I just wanted to know your thoughts on this.
