I have an infestation of ground boring bees. They are in the ground cover, under the shrubs and trees - some even in the brick walks. There are so many around the house that there is a humming noise. They also sting. How do I get rid of these bees - there has to be thousands of them. This problem has existed for the last 2 or 3 springs - they are around for a few weeks and then disappear.

Mining bees are not aggressive. Only the females sting. As you say, they are only out for a few weeks and then disappear. They are very beneficial insects. The following publications deal with getting rid of them, although it is very difficult to get rid of them totally. http://extension.umd.edu/hgic/mining-bees-lawns
