Pediculicides are used to kill which of the following?

Pediculicides are specifically formulated medications designed to treat and eliminate lice infestations, which includes adult lice. These treatments work by targeting the biology of the lice, disrupting their life cycle, and effectively killing the parasites. This is why the answer pertains directly to adult lice, highlighting the effectiveness of these agents in managing infestations and preventing their spread.

Fleas, ticks, and ants are pests treated with different classes of insecticides that are formulated for their specific biology and behaviors. For example, agents used for fleas or ticks do not have the same action on lice, as different pests may require distinct mechanisms of action to effectively control their populations. Thus, understanding the specific use of pediculicides in the context of lice versus other pests is crucial for accurate identification of treatment options.
