Tell readers they don't necessarily need to use any pesticide to rid their kids of head lice, i.e. OTC permethrin or prescription lindane. Lice and their eggs can be manually removed with a nit comb....Lindane is particularly problematic and should be avoided. In fact:
"The use of lindane, which is neurotoxic in humans, is no longer recommended by the AAP. The FDA issued a public health advisory for lindane indicating that it is for second-line treatment, should not be used in neonates, and should be used with extreme caution in individuals who weight less than 110 pounds."
For more on lindane, see this LA County lindane video which discusses its health and eco effects:

Another issue with head lice is that sometimes schools will send a kid home with alleged head lice when in fact what the nurse has seen is just dandruff....misdiagnosis is much more common than you'd think. The AAP has advocated against "no nit" policies. see:

The best web site for info on lice is run by the National Pediculosis
Assoc. They run an annual head lice campaign at the start of every
school year. See: http://www.headlice.org/

Thank you for sharing this post. I really like your writing style. :)

Thanks for the kind words!

Thanks for this information but I do have a question...if head lice cannot line more that 2 days off a human host, then why do we need to seal things that we cannot wash in plastic bags for 2 weeks??

Two days away from a human host is the average time it takes for them to die, but there is always variation in time to death; every louse will take a different time to die, so by keeping infested items sealed for two weeks, it will ensure that none survive.
