It looks a bit goofy but so far this year it has kept the bees out of our swimming pool. They are actually using it. The foam pinapple rings support a fine mesh the allows the bees to drink without going swimming. In 2 weeks only two have managed to drown themsevles. When the legally blond types of the hive have been going to the swimming pool I was getting a dozen drownings a day... not to speak of the nervous wife when she was in the pool.
I'm going to order another soon.
"hobby farm" is an oxymoron
