Pond plants

Pond plants

I live in Minnesota, so the winter temps get well below freezing here. What should I do with my pond plants? I have some really beautiful ones, and I'd hate to lose them to the cold temps. What should I do with them over winter? Should I bring them inside? I'm for sure going to bring a few plants in. What can I treat them with to kill bugs and othe nasty things I don't want in my house?
