get for real people. sorry to seem rude, but motor oil? concrete, shaving? come on...... I thought this was a site that promoted healthier living. The DE is a great idea, and it works. I have not heard of Basic H for lice, I use it for worms, I put it in their water. Another idea I discovered was one time I put Apple Cider Vinegar in a pan for them to drink ( for worms also) and some of the pigs with lice tried to wallow, or lay in the pan, so I poured it on them--kind of bathed them in it-- . I am not sure which one of the many things I tried is the one -or combo- but no more lice. and it was natural, and easy.
