Dengue fever remains one of the most prevalent infectious diseases during the rainy season, spread primarily by Aedes mosquitoes. Surveys have found that the Makkasan Preschool Child Development Center is among the at-risk groups in the area surrounding Bumrungrad International Hospital, due to limited outdoor space for daytime activities and the presence of numerous stagnant water sources.

The Bumrungrad Hospital Foundation and Bumrungrad International Hospital, in collaboration with VP Mosquito Control Co., Ltd., the authorized distributor of Biogents GmbH — a global leader in mosquito control innovation — donated BG-Mosquitaire Co2 mosquito traps, along with educational materials on mosquito life cycles and species, to the Makkasan Community Child Development Center under the “Mosquito-Free” Project in 2025. Now in its second year, the initiative aims to improve knowledge, understanding, and awareness of mosquito-borne diseases, with the goal of strengthening prevention efforts and building sustainable community resilience.

The BG-Mosquitaire Co2 mosquito trap has been widely recognized among entomology researchers worldwide for over 16 years. It works by releasing carbon dioxide to mimic human breath, combined with synthetic sweat odors, heat guidance, and airflow direction, to effectively attract and capture multiple mosquito species.

With the project’s implementation in 2024, more than 150,000 mosquitoes have been trapped — an average of 30,000 per month. Between August and September of 2024, the percentage of children in the community suffering from mosquito-borne diseases has reached 0%. The majority of captured mosquitoes were Culex (carriers of Japanese Encephalitis), followed by Aedes (carriers of Dengue fever), and Anopheles. The trap has been patented for its environmentally friendly design, which reduces chemical use and minimizes pollution.
