Hi
I am posting here rather than replying in the emails because I know the frustration of getting forums going from my experinece nurturing along the Oxford Forum - and I also know how good forums are when they get going!!
My understanding of headlice is that the only good treatment is insecticide of some kind, repeated after 1 week. I always thought that the lice really don't live long enough off the head to worry about.
Wet combing can also be used and I have found that our clinets are quite open to doing this as a supplementary back up.
The real difficulty would seem to be coordinating getting all the heads treated at the same time - it only takes one untreated head to restart the whole cycle. In this kind of camp scenario, it might be good to have a meeting and agree to have a camp - head session, where everyone gets treated together on one evening / night - could make it a social event with food etc as a bonus!
We don't bother with clothing / bedding changes for headlice - only if clothing lice are involved.
The following is a link to the UK management guidelines.
