Hi everyone. I’ve been using about 5mm of vegetable oil in the pest tray with very good results in controlling small hive beetles. They end up in the oil and can’t get out. I’ve seen so many more drowned than I had any idea were in the hive.
However, given Melbourne’s cold weather the oil has thickened up and some of the bee garbage is staying on the surface instead of sinking completely.
Has anyone tried plain water or even vinegar instead of oil? I thought vinegar would be great and would seal off or prevent any mould on bee rubbish… but vinegar has a strong smell and I’d hate to bother the hive
