Finally after fifteen years of this lady two doors down having her lawn professionally sprayed for insects, to which I blame for the decline of bees, she moved. Last year I followed some tips on planting flowers that attract the most bees and placing a shallow dish with some flat rocks so they can land on the rocks then drink the water, it went really well. We had one set of bees build a hive on top of a pillar on the front porch. We decided to leave it there and have conversations with the grand kids about how important they are and if you leave them alone they'll just be busy being bees.
