First year beekeeper; one of my hives has gotten extremely aggressive.
Is there anything I can do? At the beginning of the year they were of course totally sweet and calm, but as they've built and filled lots of comb, they've become extremely aggressive. I'll just open the hive and I'll instantly get multiple stings. Am I doing something wrong, and is there something I'm not doing that I could be doing to mellow them out? I use top bar hives and give two puffs of smoke at the entrance before opening it up.
