I'm at my wits end. DD (10yo) has had them about 8 times in 6 years now. I'm so sick of it. I should have shares in Vermox at this stage!
The first time she got them I wanted to rip all my skin from my body and I don't feel any less dramatic and horrified this time. I do everything I'm supposed to do, clean the house, dust, wash everything in hot water, treat the whole family, we all know about personal hygene, the incessant hand-washing, no nail-biting, dd even has a small bottle of hand disinfectant in her schoolbag but she's still getting them 
I've written to the school head who issued an information page to all parent on how to properly treat an infestation but obviously not every can be bothered to insure they treat it effectively or are treating at home but not advising the school and so the cycle continues.
So I realize I can't stop the spread of it outside my own family but wtf else can I do to stop dd getting them. I thought about treating with vermox every 8 weeks just to be sure but I doubt that's safe to do. I've heard garlic is a natural remedy so I'm buying odourless tabs today and I've just seen something on the internet with a weird name abbreviated to DE (something Earth) but it's also used to treat animals and in farming so doubt I'll be dosing dd with it.
Has anyone heard of or used an everyday supplement or anything that can inhibit their growth before they start to come out at night, the little b**tards 
HYCH
TIA
Yours, fedup mum.
