During the 1907s, Jonathan Green worked with a malaria control program in South Central Thailand’s Control Zone 3. Accompanied by a crew, Green ventured into the jungle to spray local villagers’ homes with DDT. If individuals suspected they might have malaria, the organization administered a blood test and provided medication for those who tested positive.
Here, Green wears his khaki uniform, like other Thai civil servant officials. According to Green, his boss suggested this type of uniform because villagers would be more trusting and recognize him as an official.
Green’s work took him into the jungle to visit local villages.

Jonathan Green wrote, “Each sprayman carries a canvas bag containing several plastic bags of powdered DDT, his sprayer, and a bucket in which to mix the DDT with water. Powdered DDT is not soluble in water, so it is hard to mix. But then the whole idea is to spray a suspension on the interior walls of homes, so the water will evaporate and leave the powder adhering to the walls to kill mosquitoes who like to rest there.”

Jonathan Green’s collection is the only one currently in the Peace Corps Community Archive documenting a volunteer’s experience in Thailand. Green wrote detailed captions explaining each image and elaborating on his Peace Corps service.
