Does this photo suggest robbing to you? I can’t recall a time when I have clusters of bees at strange entrances. It’s a very strong hive, producing well now in spring. Lots of flowering plants near me (Brisbane), so no idea why they’d go to the effort of robbing mine?!
If it is robbing, will they eventually give up because the hive is strong? I haven’t reduced the entrance/closed it up/placed wet blankets yet as I haven’t seen many actually get inside, and certainly not come out laden with honey.
Would love some advice please!
