I’ve just had a worrying experience with my hive (started as a nuc this year) – a big cloud of bees around my head and essentially attacking my head as soon as I took the (two full) supers off. I didn’t even begin the inspection – just closed it up and most of the cloud stayed around my head and followed me back to the back door of the house. This colony tend to be quite tetchy (the odd sting and follower) but never like this before. Any ideas about what I may have done? Weather etc. seems ok. I’m beginning to think I may not be cut out for this!
Your colony sounds as if it might be queenless but don’t panic yet (there’s nothing you can do at this time of year if they are queenless except to try and buy a new queen from somewhere.) The bad temper may be for other reasons so it might an idea to give it another go.
Light your smoker, use it liberally and make sure you are well suited up – and look for eggs and small larvae.
