Hello all. I guess its that time year....the robbing time of year. I have one particularly strong hive (started from a package this year...Italians) that seems to be menacing all the other hives. I can tell them from the other bees I have as they are much lighter....and there flight paths to the other hives very obvious. They first went after the weakest of my hives...one that I had just re-queened. I reduced entrances, put a damp sheet over the targeted hive, etc. When I noticed that the weaker hive didn't seem to be fighting them off anymore...I opened that hive...found few bees and no queen. As this has been a weak hive since day one, I just decided to let nature take its course...and let the robbers have it. Then an over-all frenzy seemed to commence with the robbers going after the other hives as well. I moved the original, target hive to a new location...hoping the robbers would leave the other hives alone...no such luck. This is now an ongoing challenge in my bee yard. I've reduced all the entrances (including the robbing hive) down...but there is continued fighting and dead bees littering the ground. What more can/should I do...what might I have done differently in the beginning? Any advice appreciated.
