Interesting to know about them! We resorted to Lice Knowing You when we had the infestation last year. They do removal by hand and have a 30-day guarantee if everyone in the house gets treated at the same time and you follow their instructions. (Basically to quarantine or run through the dryer all bedclothes and stuffed toys that the kid sleeps with). Every so often I think of that as being a fantastic business to go into: you get to charge $95/hr and people are more than willing to pay it. You'd just have to be able to weather the seasonal ups and downs.
