You can stick juicy fruit gum and human hair into the tunnels, the hair makes them itch and the gum they eat. We did it and it worked great. We got the hair trimmings from our hair dresser.
Open up their tunnels and drop down Moth / Campher balls. They don't like the smell and leave. It also works for squirrels.

Having tried all of the above and failed, get a cat.
