The Lice Problem: I'm scratching my head on this one

How have some of you educated your parents and staff about the realities of lice. We currently have approx 6-8 kids who have or have been treated for lice. I'm receiving phone calls from parents, the newspaper, and Dr.'s offices concerning the "outbreak" in my building. It's becoming very frustrating. We have done everything that we can do to control the problem, trash bags, sitting alone on the bus, checking kids before they get to class upon returning, checking the whole class, sending letters home to the class. What have you done in the past to educate your parents without causing a concern. Let me know.
