I put a trap in an area where I had seen bee activity before. Single used deep with three well used frames of comb. Today, I saw a lot of bees coming in and entering the box. Not regular hive activity, but either investigative, or local bees harvesting some tidbits. No honey in the frames. Can you differentiate between the two behaviors? What would I look for if there is an observable difference? Seems like the bees are checking things out but might just be trying to locate the "goodies".
