Tom O'Brien crossed for a third team try after the break and Rhys Patchell added 12 points with the boot.
Gethin Hunter continued his good form for the Scarlets with two tries - that's six for the season - whilst Daniel Evans and Jordan Williams made sure of a bonus point for scoring four tries.
Williams ended the game with 10 points but finished on the losing side as the South held on in a frantic finish.
