How is DDT spraying for malaria different from spraying for agriculture?

Evidence from countries that continued using DDT showed that correct and timely use of indoor spraying can reduce malaria transmission by up to 90%. In the past, India was able to use DDT effectively to substantially cut the number of malaria cases and deaths.
