The World Health organization announced its approval for the use of DDT indoors, as a positive move to combat life-threatening malaria. DDT, a popular pesticide, was banned after it was found to be harmful for wildlife and birds.
Dr. Arata Kochi, director of the World Health Organization (WHO) malaria department 'One of the best tools we have against malaria is indoor residual house spraying. Of the dozen pesticides WHO has approved as safe for house spraying, the most effective is DDT.'
This is by far the most inexpensive option of making the house free from mosquitoes, and keeping the dreaded malaria at bay, known to kill about a million people annually.
