Participants pointed out that successful larval control was possible only if carried out by all households and control agents were accessible and available. People’s perception of the effectiveness of control is based on the reduction of adult mosquitoes not larvae. Getting rid of Aedes larvae from water containers may not reduce the number of adult mosquitoes greatly, as other mosquitoes were found in and around houses. Therefore, people perceive that the Aedes control program is not effective or responding to their problems.
