The work, led by the Ministry of Heath, took place early June.
"Fumigation is one of the main priorities of the Ministry of Health and it is also a way we could show support to the Government of Samoa as we prepare for the Games," said Sapati Vasa, Ministry of Health Senior Sanitation Surveillance Officer.
The Games Village will host more than 4,000 athletes and preparation is going well.
"Fumigation deals with the elimination of unwanted pests such as mosquitoes which carry diseases. We are looking at getting rid of their breeding areas," Sapati continued.
