Using Frogs to Control Ants?

Last summer my garden was overrun with ants. I tried lots of different things to get rid of the ants but there were way to many. So I was thinking of setting up a frog house in the garden this summer to see if the frogs will do a better job then I can. Do frogs eat ants as well as other garden pests? Has anyone used frogs to help control garden pest problems, mainly ants? Any advice would be greatly appreciated.
