I live in Chicago -- in the city -- and have a garden, pond, vegetables and flowers. I want a frog or two for my garden to help control insects.

Inside the house I have two white's tree frogs and three firebellies -- and I know these guys stay indoors.

My question is -- where do I get frogs for outside. Various posts say build/get a frog house and they will come . . . but that doesn't happen in the middle of a city.

Any suggestions?
