Happy to help. I am still battling(3 years now) a similar problem with my KBG/PR lawn having been invaded by creeping bentgrass.

John, I appreciate your time in returning a helpful note to my post. I was wondering with what you did mention on if I could use a type of grass killer on just the affected areas with the fescue.
You could do that. A full scale renovation of the affected area. Kill off the whole area with the undesirable grass and re-
seed with bermuda. That would help the cause. That grass is most likely spreading by creeping(Stolons and Rhizomes)AND by
seed that gets scattered when you mow. If you kill it off before it goes to
seed, you will help yourself. Use Round-up or another product containing glyphosate that will kill everything it's sprayed on that is actively
growing. You could then re-
seed within a week or so. Just read the product label carefully to be able to apply it properly.
