Invasion of the Tree Frogs!

Does anyone know a solution for getting rid of tree frogs? While Maryella loves trying to "catch" them through the window, I'm getting rather tired of their dirty little legs hopping all over the glass. Sometimes it's so bad that you can't see clearly out the window the next day! And they also stay all around the back door. Anytime you want to go outside, they jump on you. Ahhhh! Seriously - any home remedies that you have heard of would be greatly appreciated! (And it doesn't necessarily have to be a humane option at this point!)
