it may take a week for them to calm down again.
I once ran into an apiary that kept being moved off a yellow sweet clover bloom to avoid aerial spray, not once but three times as the pilots kept changing their minds about where they were going to be the next day.
The whole yard got nasty - even the commercial beekeeper noted it. Two months later, they were still angry, which surprised me. We sampled them before the moves - no problem. But working them after all of the moves away from a flow, they got mad and stayed mad. I'd have thought, once the initial worker force had died off, the aggressiveness would disappear - it didn't.
