Itch Itch Scratch Scratch!!
schoona i never had lice while in school either, but my daughters who both had hair to their waists got them...what a lovely time that was! I know it's not a proven preventitive....but after the first time of the nit pic threw their hair I started rinsing their hair with diluted white vineagar. Never had a problem after that!! (I also use vineagar sprayed on bandana's in the summer to keep black flies away while I'm gardening-works great!!) Seems like lice is such a common thing now days....the school nurse told me it was really no big deal when I called her just slightly flipping out. Maybe its that attitude, maybe its the cost of treating, maybe its the work involved in treating the whole house that has made it 'no big deal'. But when I was a kid....ya didn't wanna be the one with cooties!!

As far as scabies go....facility I work at had a major outbreak...and guess who did manage to get those...and bring them home to share with the whole family.!! Husband was livid! It was almost the end of my working there. (10+ years and never brought any thing home!! except a pen or two

) At that time I was working as a CNA (LTC) and there is just no way that I can think of to not have skin to skin contact (arm under the shoulders for turning, etc.)
