Evidence of pesticide resistant head lice in Scotch Plains, NJ.

These bugs and many more were recovered from the head of a recent client after having used Nix(TM) a permethrin-based, OTC lice treatment “shampoo”. While it is not uncommon for me to see pesticide resistant lice leading to treatment failure, it never gets easier for me to witness.

Well-intentioned parents, sometimes guided by the advice of a medical practitioner, journey to the drug store and purchase either Permethrin or Pyrethrins with Piperonyl Butoxide to treat their child(ren)’s head lice problem. The lice pictured above were recovered AFTER a child was treated with the product and AFTER the parent spent copious hours combing the child’s head with the comb included with the kit. Pictured above are every stage of live lice. This means that most of the bugs there were present at the time the child was treated with Nix(TM) and they were not eliminated. In addition, due to the poor efficacy of the comb, hundreds of nits were left behind. Many of the bugs that I removed from the child’s head were first stage nymphs, indicating that they had hatched, most likely, AFTER the initial treatment. Thus my findings directly contradict the product packaging which claims that the product “kills lice and their eggs.” Please see the following picture to better understand the four stages of live lice.

When dealing with pesticide resistant head lice, no amount of pesticide will work to eliminate the problem. While lice may develop a resistance to neurotoxic pesticides, they cannot evolve beyond the need to breathe and excrete. Dimethicone, a perfectly safe and non-toxic silicone oil, interferes with the human head louse’s ability to breathe and also to excrete liquid waste. As a result, they die after being exposed to it. I work with KaPOW! Lice Attack Solution, a safe, reliable, non-toxic dimethicone-based product created and manufactured by The Center for Lice Control (http://www.centerforlicecontrol.com).
