Re: Problem: Bees in the birdbath
The birdbath water is most likely warmer than the pond and the creek. And if water is too cold, bees won't use it. So you will need to provide an alternate source of water that warms similar to the birdbath. It would also be useful to give it a distinctive odor. Water with chlorine (swimming pool water), compost (rotting leaves, etc), manure all have distinctive odors and have been reported attractive to bees.
