I've been through the same thing. We were always the bad guys torturing the kids by treating and scraping them everytime we saw them. BD pulled live lice out of BM's head and she still didnt believe it came from her house. She would sometimes treat them, but would not follow the directions on the package. Sometimes she would use an alternate treatment like coating with mayo or even once died their hair.
It was a major problem for us because of my daughter that lives with us. BD's kids would come over and immediately we would have to "do heads" to prevent it spreading through our whole house. Sometimes it would take all weekend and then we would have to send them back to get it again. Hardly seemed worth it.
Now for your question, there is really nothing you can do about it. All she has to do is say she is working on the problem. You cannot prove that she is not doing so, right? It really sucks but technically they are not being "harmed".
