Well, what a day today, while at one apiary at noon I heard a big roar looked across the apiary to see bees swarming out of one hive. Such a lovely sight to see bees swirling in the air. I thought I'd try a bit of tanging, hive tool against the guard of my dadant smoker and they dropped to the ground which made it easy for me to collect. Old brood frames over the cow pat cluster and up and onto the frames they went. Travelled to my other apiary and what do I find. I'd left a space in the apiary where I shook out drone laying workers last week to put in place one of my other hives this week. Only someone else's bait hive in that spot, it consisted of a roof and empty nuc box and inside was a swarm of bees. Phoned the farmer who saw a blue BMW shoot off from the entrance last Friday, luckily he has the number plate, I took a photo of a Ford Focus today that parked outside the entrance after I had turned up. For all i know they may be totally unrelated and innocent. Their nuc box has now been removed and they will have to contact me if they want their decrepit nuc box back. There is only one beekeeper who has bees close by and he is an ex-policeman.
