I am having a terrble problem with 2 bees that keep digging holes in my grand daughter's flower bed. I have tried flooding the holes, covering them up, and even filled them wih diatomaceous earth and nothing has worked. Does anyone know how to get rid of them? One bee is small but the other one is about 2.5 inches long. You can see pictures at: http://s428.photobucket.com/albums/qq8/Piper2810/
If you look close in the middle picture you can see the smaller of the 2 bees.
