Re: High certainty swarm prevention in dense suburb
Sterlinggold, Ruthie is in Hampton Roads, I am outside of Richmond. For us, these manuevers must be completed by the second week of April. My plan is April first this coming year because several of my hives swarmed last season mid-April. If you are DC metro, follow the same time line. If by Winchester, you have an additional week or two.
Vance, I like the ease of your method vs flipping the doors of a Snellgrove board. Especially since it does not involve a piece of additional equipment.
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
