Since mites have decimated the wild honey bee population, leaf cutters and bumbles and some others are all that we have left to do this important job. snip Weren't these the mites that the government decided were just the thing to control the Killer Bees? Just like Kudzu to control soil erosion? We had no bees here for about three years, but I'm happy to report that they're back, so don't give up hope! Marilyn
