In my experience, the sprays do not work at all. Try blotting the pad with some of her own pee from an accident. Then make sure to clean up any accidents with an enzyme cleaner, like Nature's Miracle, so that the only scented place is the pad.
Are you using an xpen or anything like that? A lot of people just line the entire xpen with pads so wherever she goes, she's on the pad. Then they gradually cut back to just one pad, or train for the outdoors.
Good luck!
