My bees wouldn’t stay out of my dog’s watering bowl and not only were they annoying her but they were drowning in large numbers.
At first I tried using a bird bath and changed the water twice a week for my bees, but never saw them using it. I think it was too close to the hive (they like their water source to be a bit farther away from the hive) and the birds were always in it.
So then I turned a medium sized pot into a water garden with plants and a piece of wood for them to land on. The bees are loving it! Every time I have gone to check on it there are 20+ of them drinking. Since I have set up the garden I have not found a bee in the dog bowl.
As for preventing mosquitoes, I plan on ordering a few tadpoles or feeder fish.
