Indoor residual spraying using DDT and pyrethroid insecticides constitutes the backbone of South Africa’s malaria control programmes.; ; Effective vector control by indoor residual spraying has been key in the reduction of malaria cases. This was instrumental in creating malaria-free zones in most parts of the country. Malaria transmission is now limited to the north-eastern parts of Limpopo province, the low-veld areas of Mpumalanga province and the far northern parts of KwaZulu-Natal province.
