I have bees in my lawn! They look a little like honey bees, but smaller and redder, so I guess they are mason bees. My dog has been trying to dig them out, and wondering what she was doing I watched a hole for a while. Along came a bee and it walked down into a little tunnel. There are at least 5 individual holes, I guess one per bee.
My problem is the lawn also has lots of moss, and was due for a 'weed and feed' treatment. Does anyone know if this will affect the bees? They have already survived at least two mowings.
