Heavenly Bamboos (Nandina domestica) is a lovely plant but it is extremely invasive and if all roots aren't removed it can spread by underground runners. Smaller plants can be pulled out easily by hand but large, mature shrubs will have to be dug out or yanked out by a heavy truck with a chain, as you've stated your dad might be able to do. Seeds remain on the plants for many months so it's a good idea to dig the plants before the seeds appear.
