Malathion is an organophosphate insecticide used in the treatment of head and pubic pediculosis and scabies. Malathion exerts its action on the nervous system of the lice by irreversibly inhibiting the activity of cholinesterase, hence allowing acetylcholine accumulation in synapse that results in the death of the lice.
