Bee in the bird bath. I placed a stone in it that absorbs water and the bees can land on it and suck the water from the stone. No more drowned bees. You can also add a sponge or Loofah that is all natural and they will get the same results. The brighter the sponge the more bees you will attract. Do not add sponges that have chemicals like soap added for cleaning. Shot in my backyard in San Angelo Texas.
