Unfortunately, Bermuda grass is so closely related to St. Augustine grass that there is really nothing that will remove Bermuda from St. Augustine and not hurt the St. Augustine as well. In your situation it is recommended to spot treat the Bermuda with a Roundup-type product to kill it directly, and then replant St. Augustine in those areas. We do have some professional Roundup products available on our website here.
