INTRODUCTION: In dengue epidemics or outbreaks, insecticides play an important role in controlling adult mosquitoes and in supporting the vector control program in Cuba. OBJECTIVE: To find out the effectiveness and efficiency of insecticidal formulae for Aedes aegypti mosquito control in Santiago de Cuba province and to draw up the strategies for use. METHODS: Bioassays were performed according to the WHO methodology. The efficacy and efficiency of cold fogging and thermal fogging methods were compared through Mann Whitney´s U test. The comparative analysis of the efficiency of both methods and every formulation was made using Kruskal-Wallis test. RESULTS: When comparing the mortality indexes from both methods, it was observed that there was a highly significant difference between them, being the thermal fogging method the most useful because of its efficacy and efficiency (cost effectiveness). CONCLUSIONS: Kruskal-Wallis test proved that there is a highly significant difference among the various formulations. Galgothrin 25 EC is the most favourable and efficient without DDVP.
