Mint is a prolific plant, so there's no need to control the beetles. If you're worried, you could try growing pennyroyal, Mentha pulegium as a sacrificial crop, or simply remove beetles and larvae by hand and squish them. You could also spray with organic pesticides based on pyrethrum in spring and summer.
