The malaria is one among the major problems of public health in Democratic Republic of Congo (DRC). We can notice today that even though the progress observed in the struggle against this curse and the important means placed at disposal by the international community, some big gaps exist as for the results of land between regions through the world, the countries and even of the meaningful differences inside a same country. The national strategic plans 2016-2020 of the RDC plan a stratification of the malaria for a differentiation of interventions according to the strata. Our study is the descriptive and analytic type survey has the object to show the difference of behavior in the use of the MILD in the sanitary districts covered by the PARSS/RDC project. to achieve this survey, we used the data collected by the PARSS project. Among the individuals interviewed at the time of this investigation, we kept the women old 15-49 years of the health areas sampled for the investigation. The results show that among the factors of stratifications that discriminate the sanitary districts better, one can mention the natural gates making difficult the geographical accessibility in some zones; the lack of adequate infrastructures for the circulation of goods and people. For achieving the struggle better against the malaria in a vast country as in Democratic Republic of Congo (DRC) , with a diversity of biodiversity and culture, a stratification of the needs and the policies of approach can drive to the results.
