%X <b>Introduction:</b> Culicid mosquitoes, such as Anopheles, Aedes, and Culex, are capable of transmitting vector-borne diseases such as malaria, dengue fever, yellow fever, and Japanese encephalitis. When their density is high, culicid mosquitoes are also a source of nuisance, discomfort, itching, and skin irritation. To control these Culicidae, it is important to understand their bioecology and the composition of the Culicidae fauna.<b> Objective: </b>The objective of this study was to assess the diversity of the Culicidae fauna and its aggressiveness in three dormitories at Marien Ngouabi University. <b>Methodology:</b> Culicids were collected using two methods: morning collection and collection of species aggressive toward humans. <b>Results and Discussion:</b> During this study, 2621 culicids were collected. These belonged to five species: 2519 <i>Culex quinquefasciatus</i>; 80 <i>Anopheles gambiae s.l.</i>; 16 <i>Aedes albopictus</i>; 4 <i>Aedes aegypti</i>; 2 <i>Mansonia uniformis</i>. The Culicidae fauna consisted primarily of <i>Culex quinquefasciatus</i> (96.11%)<i>.</i> In terms of nuisance, the highest level was recorded at the ENS I residence, with 400 p/h/n (bites/person/night) for <i>Cx. quinquefasciatus</i> outside the bedroom. The presence of mosquitoes in university housing is a major concern due to the nuisance caused by mosquito bites and the risk of vector-borne disease transmission. Several factors could contribute to the presence of Culicidae in these housing units: proximity to a watercourse, weather conditions, and outdoor maintenance, although these variables were not directly measured in this study. <b>Conclusion:</b> Management of the nuisance caused by Culicidae in university housing can be achieved through environmental management, vector control, and student awareness campaigns.
