Vantage grass killer works on thin bladed grasses, like Bermuda, without killing centipede. Using as directed, it does a decent job, with results in about 2 or 3 weeks. The only problem, as anyone dealing with the "devil's weed Bermuda" knows, it is next to impossible to completely eradicate the stuff. This is the best product I have found that at least keeps it at bay and doesn't harm the centipede. You will need to retreat emerging Bermuda about every 2 months or so.
