After harvesting a super of honey I gave the bees back the empty wet frames for them to lick clean. I did this first thing this morning which sent the bees into a frenetic buzz looking for the source of this amazing food. This meant loads of foragers went looking for it outside the hive. It took them about an hour to realise that the food was not outside the hive but inside the hive above the clearing board. During that hour I had hundreds (or so it seemed) of bees checking out the porch, kitchen, lounge and garden.
Must remember to only do this operation at night when the bees are confined to the hive.
