Got a call from a friend. She was terrified to see hundreds of bees entering/exiting dozens of pencil sized holes in a planting bed next to her house. Based on the pictures I tool and looking online it appears to be a species of sand bee. From what I have read its difficult to relocate the underground hive due to the deepness of the burrows (greater than three feet). Does anyone have experience relocating a nest? Short of moving a cubic yard of soil how would you do this? Thanks all.
