Its a delousing powder, so its kills lice.


Often in unsanitary conditions it spreads past peoples hair and gets on their body. It casn even burrow into the skin.

It's like the pet product we call ';flea powder.'; It kills fleas, lice, and body ';crabs.'; They call it ';de-lousing'; powder (louse is the singular of lice)
its to de lice them.. there is so much lice in prison and the only way to rid it is to use this powder.. and thats a fact...
