yes I tried the hair dryer on her head but it didn't seem to work very well. Maybe I just didn't do it long enough? I did resort to putting DE in her hair and that seems to have died down her itching. The bugs are teeny tiny (like the tip of a push pin, tiny) looking like specks of dirt but if I watch, I can see the specks move. It could be from pets since we have two dogs and a cat but none sleep in our beds. Thanks for the info so far. I'll try the vinegar this afternoon.
