Cut it back as necessary :-) And you can also pull up the longer, traveling extensions relatively easily.

I have seen acres after acres of vinca escaped into remote forest areas in upstate NY. Highly invasive.

I trim mine once a year with a string trimmer by cutting down the height where needed and edging it to keep it from growing too wide or near other bushes. Hand picking of some of the runners that the trimmer does not get has kept it well controlled.
