Fenthion is an organothiophosphate insecticide. The mode of its action is blocking acetylcholinesterase (AChE) in synapses of the central nervous system of a parasite this resulting in its death. Fenthion penetrates poorly the hematoencephalic barrier of warm-blooded animals, but, if applied externally, is easily absorbed through the skin and enters the blood. Blood-sucking parasites die due to the entry of fenthion into their organism with animals’ blood.
