I've had poultry lice once and got DE bc it was more readily available. I used it for that one episode and have never seen a louse since. And I regularly check for them. But I would definitely try something else just for experimentation if I ever need to. Just hasn't been a problem again.I don't know enough about DE, havent used it. But please, if you want to get rid of external lice, skip the DE and use Permethrin dust or liquid spray. As for mites, you'll probably need something else other than the two.
I deal with lice every season, and python dust does the trick in ridding the lice very well.
