I nearly died of malaria in the middle-east, but never got it in Kenya and Somalia when I lived there.
You don't need DDT or any poisons to get rid of mosquitoes, we used frogs and fish. Any puddle of sitting water was filled with sand as quickly as possible. And any largish natural body of water got fresh-water fish and frogs introduced to it. No questions.
In Kenya (Mombasa) and south Somalia, even sea-water fish worked for us. I used to take off my Sarong and catch little fish for our wells.
