dd1 has had nits tiwce since starting school in september. each time i've seen eggs- dead ones, i'm pretty sure, but no lice.
the investation seems to have gone by itself, each time. i'd always assumed that lice would multiply until treated, not disappear voluntarily!
i realize that a single louse can lay many eggs, then scarper, but surely those eggs would hatch....
anyway, can anyone explain why we have nits but no obvious lice?
also, can anyone suggest a foolproof way of knowing if the eggs are really dead?
