Find where bees are drinking water. When they are filled, they fly straight home, straight as a bee-line. Stories are that my Great Grandpa could throw some honey on a post or side of a tree, and in that situation, bees will fill and go straight home. He could tell you where in the wild the hives were that the bees went to as they flew off. So if you set out some honey or strong sugar water for the bees to get, they will be filled so will fly straight home. When gathering from flowers, it takes more than one to fill so they don't always fly straight home when done with a flower.
