D.D.T不但能殺滅頭虱,對體虱及陰虱也都是極有效的,他的用法也很簡單,用小量的10％的D.D.T滑石粉末,散在頭皮上就可将它殺死,但每週必須散布三、五次,因為它不能殺死虱卵(蟣),長期散佈才可以將剛孵化出來的幼虱一併殺死,此外更应當注意的就是D.D.T的油溶液,易被皮膚吸牧,應當忌用。 DDT can not only kill head lice, but also is very effective for body lice and genital warts. His usage is also very simple. It can be killed by using a small amount of 10% DDT talc powder scattered on the scalp. It must be scattered three or five times a week, because it cannot kill quail eggs (cockroaches). Long-term distribution can kill freshly hatched larvae. In addition, it should be noted that DDT’s oil solution is prone to skin damage. Absorption should be avoided.
