I use baby diapers on Cody when he goes on the floor, he hates them! So we have very few problems with him.
Another suggestion (I just thought of it

) whether you have a yard or not put her on a leash that way when she goes into the house she's still attached to you and you can grab her up if she starts to go on the floor.
