A survey of variables in DDT application and their effects as determined by contemporary experimental research. Variables discussed include the type of surface to which the formula is applied, the manner and formulation in which the DDT is presented, climate conditions, the amount of rubbing to which the surface is subjected, and others, all of which may influence the efficacy of DDT. The volume is intended for the field worker who may not have access to literature on DDT, and focuses on practical applications of experimental research results.

DDT (dichloro-diphenyl-trichloroethane) was developed as a synthetic insecticide in the 1940s. It was initially used to combat malaria, typhus, and other insect-borne diseases. The EPA banned DDT in 1972 after research showed harmful impacts to wildlife and potential human health risks.
