I normally use vinegar but 3 weeks ago one of my kids had them. I used vinegar straight away but he still had live ones so I went and got this shampoo from the chemist and bought a tea tree shampoo from woolies

I treated everyone with the tea tree stuff and the nits didn't get spread. I treated infested child each night with the tea tree shampoo. And for their bedding I put tea tree oil and lavender oil in a spray bottle with water and sprayed their bedrooms
