does everyone here like frogs?

I know several local ponders who hate them as much as I do. Our pond is
just outside my daughter's bedroom window and the noise is enough to keep
anyone awake at night. I often find her camped out on the floor of her
brothers' room. What can be done to minimize the attraction of them. Our
pond is not very naturalistic, as it is just a rectangular koi pond with an
urn fountain in the middle.
