This article focuses on the effectiveness of dichlorodiphenyl trichloroethane (DDT) as an insecticide. DDT is particularly effective against the mosquito that spreads malaria and lice that carry typhus. DDT is not metabolized very rapidly by animals; instead, it is deposited and stored in the fatty tissues. The biological half-life of DDT is about eight years; that is, it takes about eight years for an animal to metabolize half of the amount it assimilates. If ingestion continues at a steady rate, DDT builds up within the animal over time.
