Introduction: As of 2013, there were 97 countries with sustained malaria transmission, and 7 countries in prevention of the reintroduction phase, making a total of 104 countries where malaria is presently considered endemic 1,3,10,15,24. It is estimated that 3.4 billion people are at risk of malaria and WHO estimates that 207 million cases of malaria occurred globally with 627,000 deaths in 20121,3,10,15,24. 80% of cases occurred in Africa and most deaths (77%) occurred in children under the age of 5 3,7,10,15,23,24. The burden faced in Sub-Saharan Africa continues to be a challenge for national governments. Increasing resistance to drugs and pesticides, the lack of capacity to implement programs effectively and low public education about malaria are only a few of the many complications that African governments must address to effectively combat malaria 1,3,7,10,15,18,20,23. In order to reduce malaria incidence, some African countries are moving back towards dichlorodiphenyltrichloroethane (DDT), an insecticide once widely used throughout the world for agricultural and public health purposes1, 3,10,15,16,23. Dr. Paul Müller discovered chemical DDT effectiveness on insects just prior to World War II. His work received the Nobel Prize in Physiology or Medicine in 1948 1,9. During World War II the Allied forces used DDT to combat typhus and malaria vectors 15. After the war they used the chemical to control the vector and agricultural pests, helping to successfully
