Went into a hive 7 days after last inspection. A week ago there were cups, but I pulled down all the ones I saw and there were no eggs in anyway.
Today, found multiple capped queen cells along the bottom of frames, where I am always diligent to check. Swore loudly, but hive very busy, so separated all the boxes to bleed the flyers off, and started looking for the queen. Found her - hurray! Put her in a nuc box on her own, but left the entrance open ....
3 minutes later, as I am dividing up the hive into nucs, I hear a roar, and realise that despite the hive being split into 5 parts and scattered across the apiary floor it has decided to swarm anyway, right now. The air is full of bees. Clearly they were minutes from doing so when I opened the hive.
I go back to the nuc with the queen in and guess what - she's gone
Aaargh
The good news is that they swarmed straight into a bait hive in my apiary - no bivouac, nothing. Let's hope they stay .....
6 day inspections from now on
