In Korea, the number of malaria cases has been on the decline since 2000. Also, approximately 500 malaria cases were annually recorded in Korea. Studies have found that malaria vector control is effective at reducing malaria transmission at the community level and at eradicating malaria. Therefore, to eradicate malaria, alternative tools need to be developed to complement existing malaria vector control methods. In this study, to effectively control mosquito-borne malaria, UV-LED lights were installed in cattle sheds (a major source of malaria vectors), and larva control was conducted around cattle sheds. To measure the effectiveness of vector control, the density change of mosquitoes in cattle sheds and neighboring homes was checked from June to September 2019. The total number of mosquitoes collected (325,326) was comprised of 6 genera and 11 species. The collected number of Anopheles spp. was 142,797 (44%). As a result of the vector control analysis, the number of malaria vectors decreased by 19.1±8.9% in cattle sheds, and 74.4±9.7% in houses after intensive control measures were taken. This study provided an effective method of malaria vector control for malaria eradication. Based on these results, in 2020, plans are being made to expand the “cattle shed-centered control strategy” in high-risk malaria areas.
