Getting rid of any water source is very helpful. Our house came with an above ground pool --- and a lot of tree frogs. I rounded up a lot of frogs one night and gave them a car ride a few miles away. It was pretty funny watching the bag jump all over the front seat of my car.
As soon as we were able to have the pool removed, no more frogs. Many of our neighbors have in-ground pools, so the frogs go there.
