Nix is the one in use where I am currently at.  Greater ovicidal activity, 
less toxicity, less resistance than lindane.  I do not know of lindane being 
banned by the FDA, I thought they were too busy taking on Newt Gingrich and 
the Marlboro Man  :-}  If anyone has a specific reference for the use of 
lindane in kids, please post.  As for pyrethroids (NIX) in rats, I am curious 
as to dose, route, duration of exposure, and type of toxicity.  Remember, 
we're talking ten minutes on the scalp for common use.

Anyway, always willing to learn something new...
