Aedes mosquito is a vector for transmitting numerous arboviroses. Knowledge of the breeding habitat of this mosquito is crucial for preventing arboviroses occurrence and for implementing appropriate interventions for control. Therefore, this study aims to assess the breeding habitats and presence of Aedes mosquito species in the study areas. A house-to-house cross-sectional entomological survey was carried out in three localties of Cotonou, the economic capital of Benin in order to investigate the presence of larval breeding sites of Aedes mosquito. All available water-holding containers found in and around houses were inspected for the presence of immature stages of Aedes mosquitoes, and they were collected and reared to the adult stage for species identification. Of the 450 houses surveyed for the presence of Aedes mosquito larval breeding. About 15.77% of a total of 479 water-holding inspected containers were found to be infested with Aedes mosquito larvea. Discarded tires had an especially high positivity rate for Aedes mosquitoe larvae (54.93%) and this is perfectly explained by the marketing of second-hand tires in the study area. The dominant Aedes mosquito species that emerged from the collected larvae was Ae. Aegypti, suggesting a potential threat for arbovirus transmission. This study highlights the need for the establishment of a suitable entomological surveillance program for Aedes mosquioto. Additinally, public health education, creating knowledge and awareness of the residents on mosquito-borne diseases should be advised.
