DDT was extensively used for malaria vector control in Mexico and Central America during the 60s and 70s, but the sprayings were gradually discontinued during the 80s and 90s. The remaining stockpiles of DDT still present in the countries represent a permanent threat for the human health and the environment due to its persistence in the environment.
Successful experiences of integrated malaria vector control without the use of DDT have been developed in Mexico and several countries of Central America. The effectiveness of alternative strategies that promote community participation and collaboration between governmental institutions, NGOs, and civil groups that work at local level has been demonstrated specially in Mexico.
