We had a client come in who was in utter shock that she had head lice. She has no children and doesn't work with children. She couldn't think of anyway of how she got these bugs. Once we were done we were able to tell her how long she's had them. There she was able to narrow down to that she must've gotten it on an airplane when she was traveling. Children are not the only way people can get head lice. You can get them from airplanes and movie theatres as well.
