I have been having a lot of trouble with robbing the last week or so. The weak hives ALREADY had feeders set up inside the hives, because they don't have enough stores. I set up a large pan of syrup outside as well, to take the heat off of the 2 weak hives. I put a wet (extracted) frame across the pan of syrup to attract the robbers attention. Well, the pan was empty so this evening I went to pick it and the frame up. To my GREAT surprise, there were 3 cups of bees clinging to the underside. Now, it was LATE sunset and past the time when bees should be in their hives. I could barely see, myself. Apparently the robber bees were a homeless swarm looking for free goodies. I put an empty box where the bees are, and put the frame of bees inside it. Chances are they will not survive the winter, but I have some frames of drawn comb to give them and I have no problem with feeding them with the other weak hives. From the looks of things, I would say that we have another month of good weather, so they MIGHT be sable to store enough syrup to last them the winter. That is, of course, assuming that the swarm doesn't leave first thing tomorrow morning. Bees will be bees.
