The swarming season should be just about over by now and, unless you are in an urban environment, it is really not worth the effort of doing any more swarm control.  Instead:

• Ensure that the rape crop is extracted if you have any.
• Lime, borage, clover and blackberry are all yielding well after the recent rain – so make sure that colonies have enough supers to store the crop.  Remember that they also require working space, so do not cramp them.  On the other hand, do not provide too many supers or you may end up with many half full supers.
• Start making plans for varroa treatment in early August – another four weeks and the season will probably be finished and you will need to think about winter!  Make sure that you have healthy young bees going into winter.
• You also need to think about feeding.  The recent rain has certainly helped, but if we get another hot dry spell then bees may need some feed in early August, after you have removed the crop, to keep queens laying.
• Check colonies that have swarmed to ensure that they have managed to rear a new queen; this also applies to the parent part of the colony where you have made an artificial swarm.  Queens that have failed to mate should be removed and queenless colonies need to be united to queenright ones (unless you have a spare mated queen to introduce).  Queenless colonies will go downhill rapidly, produce laying workers and fall prey to wax moths and wasps.
• It is said that wasps are a problem on a two-year cycle - so after last year we should not see any!  However, they may start to be a problem towards the end of the month and you will then need to set out traps and close down hive entrances.
