This problem appears to be world-wide. The Department of Dermatology of the University of Bristol, in Bristol, UK, in a study conducted on 2800 school children in Wales found 1 in 10 had head lice. And of these, two-thirds had lice that were resistant to pyrethroid based treatments. The data in their conclusion indicated lice resistance in many parts of England to over-the-counter products containing synthetic insecticides (permethrin, phenothrin and malathion). They further suggest that resistance is starting to develop to carbaryl in head lice in Leeds and that extensive use of this product would lead to significant resistance.
As further documentation emerges proving NIX, RID and other permethrin based treatments to be neither the effective nor benign products that parents had been led to believe, a public health dilemma will face the public.
