The move is aimed at eliminating mosquito larvae to prevent dengue fever.

Prayut and Public Health Minister Piyasakol Sakolsatayadorn led public health officials to inspect areas inside Government House that have served as pits for mosquito eggs, including sewer lines and lotus basins.

Officials sprinkled mosquito powder and released fish into lotus basins to eat mosquito larvae.

Since the beginning of this year, the Ministry of Interior and the Bangkok Metropolitan Administration have reported 6,539 cases of dengue fever and seven deaths.

The mosquito clean-up was held before Prayut’s exercise initiative, which takes place every Wednesday. Due to the hot weather exercises were held indoors and rescheduled from 3pm to 4pm.
