Nancy always great to hear from you hope all is well. What method do you use for swarm prevention? Hopefully this year i will get to try it if my hives survive the winter.@ny12569:
No drones, yet, so the bees are unlikely to be swarming. But early anti-swarm measures are what I rely on.
I may wind up placing the SHB oil traps on each level, though I'm going to try only on the top box, for starters.
