Nice swarm into my bait hive which was set up 2 days ago. Used one frame of stores. one frame of oldish drawn comb and one of foundation. Used about 4 drops of tea tree oil and within an hour there were bees arriving and thought it was robbing but a prime swarm arrived today about 3 pm - bit windy and not overly warm.. Added more frames and a quick peep in shows they are over 8 frames now. BUT I want to add a super of Ross Rounds which in the past I have put on top of a full hive but were completely ignored. Maybe a big, new swarm might do the trick - any comments to improve the chances of success.?
