About a week ago I put a 14x12 baited poly nuc with one piece of old brood comb, and the the rest of the space added frames with new foundation...added a tissue with lemongrass to the top of one of the frames, and also smeared lemongrass near the entrance...and waited...nothing has happening (yet).......However, one of my old, unused (almost sealed) 14x12 hives, complete with old frames and old wax moth damage, (located about 25ft away from my baited nuc! ) was of interest to the odd nosey bee a few days ago....then yesterday afternoon, bang...a swarm took up residence..not in the nuc, but the old hive.....Have now moved them into the target nuc, pending a move to the out apiary and hiving. So much for my nuc baiting skills....but after a bit of a break from beekeeping I'm really pleased to be back in the beekeeping saddle !!
