Mosquito sampling in the Alulu-Nike community in Enugu East Local Goverment Area of Enugu state was performed using the human bait method, the CDC-light trap method and the spray sheet collections. The CDC-Light trap placed outdoor and the Spray sheet collection spread with a residual deltamethrin formulation were compared with the Human landing catch in the five locations. A total of 275 mosquitoes were collected and identified and they comprised of the three mosquito genera: Aedes, Anopheles, and Culex, and seven species (Aedes aegypti, Aedes albopictus, Aedes africanus, Aedes taylori, Aedes luteocephalus, Anopheles gambiae, and Culex quinquefasciatus). Specifically, the occurrence of the species encountered included Aedes aegypti 63, Aedes albopictus 29, Aedes taylori 2, Aedes africanus 33, Aedes luteocephalus19, Anopheles gambiae 27, and Culex quinquefasciatus 102 with means of 156.0 mosquitoes for human bait catch, 103.0 mosquitoes for Spray sheet method and 16.0 mosquitoes for the CDC-light trap method. Among the studied locations, Umuogbe showed the highest mosquito abundance (80.00) compared to other areas, Umuchuba also have more mosquito abundance (65.00) which was significantly different from that of Enugwu (54.00 mosquitoes) and Negbune (45.00 mosquitoes), the least mosquito populated area according to this research was Amabo which collected only (34.00) mosquitoes. The Human landing catch showed a more efficient and reliable collection for mosquitoes than others but for ethical reasons spray sheet method should be used as in carrying out surveillance in this community because it demonstrated a good correlation with the human landing catch. A standardized evaluation of more promising methods for capturing host-seeking mosquitoes should also be considered in this community.
