A chemical used in insect repellent can kill the strain of coronavirus that causes COVID-19, according to a preliminary study by Britain’s defense laboratory published on Wednesday.
Scientists at the Defence Science and Technology Laboratory (DSTL) found that Citriodiol, the active ingredient in repellents such as Mosi-guard, had anti-viral properties if mixed with the virus in the liquid phase and on a test surface.
“Mixing a virus suspension with Mosi-guard spray or selected constituent components resulted in a reduction in SARS-CoV-2,” says the study.
At a high concentration, “Mosi-guard gave a significant decrease… resulting in no recoverable virus,” it adds.
Citriodiol is made from oil in the leaves and twigs of the eucalyptus citriodora tree, which is found in Asia, South America and Africa, and is already known to kill other types of coronavirus.
The work has not been externally peer-reviewed, with the Ministry of Defense saying it was intended to act “as the foundation for other scientific bodies who are researching the virus and possible solutions.”
