Why is ddt sprayed on mosquitoes?

DDT is sprayed on mosquitoes primarily for its effectiveness as an insecticide in controlling mosquito populations that transmit diseases such as malaria, dengue fever, and Zika virus. It works by disrupting the nervous system of insects, leading to their death. While DDT has played a significant role in reducing disease transmission in many areas, its use is controversial due to environmental concerns and potential health risks, leading to restrictions in several countries.
