My daughter has had scabies and lice for almost three months. I've cleaned and scoured and bleached and washed and quarantied and numerous other things. We've used over the counter meds and prescription meds then spent three hours picking them out one by one. Then about two weeks later the symptoms come back and THEY'RE BACK!! This is the most annoying thing I've ever dealt with in my life I WANT THEM GONE PLEASE HELP... I'm desperate. Thanks
