My toddler has HEAD LICE!

I'm very clean and always instruct my child to clean up after herself. She showers everyday and is a pretty healthy little girl. Anyway, My daughter has never had head lice up until now. I called her school and apparently I'm not the only parent that has complained. They should have warned me about it or something! They swear they sent a letter to parents but I never got it! I'm so upset. From what I've read I guess lice don't care if you're clean or not :( I'm so creeped out with bugs in general. I've been washing my hearts and clothes like crazy. Is there any tricks or faster ways to kill them gross things?
