Even though I used a spatula to clean the honey out of the bucket, there was a little left over. I set the bucket out for the bees to clean up. They found it almost immediately and had in cleaned up within 24 hours. There was some fighting with small hornets of some variety, however, as well as with a few bees obviously from another hive.
Setting stuff out in the open like this, for the bees to clean up, is clearly not as good as putting it inside the top of the hive above an inner cover. Still probably better than not giving it to them at all.
