Is there anything I can do Organically to control Bermuda Grass getting into my other Beds or am I stuck with it?

I'm surrounded by yards with Bermuda grass and my lawn, before I did away with it, was Bermuda grass. Bermuda's Achilles' heel is: Shade.

I get Bermuda attempting to sneak back in my yard from my neighbor, but since my yard is so dense with other things growing it's very easy to keep under control. This plant NEEDS absolutely all-day sun. If I see some attempting to pop up over the lower-lying plants, it's very easy to pluck out of the ground, because it spends its energy growing up, not down, meaning the roots are very shallow.
