Are you a mosquito magnet? It could be your soap
Soapy fragrances can make you a target for mosquitoes as they supplement sugar intake with plant nectar when not feeding on blood.
Lathering with soap could be one of the reasons you become more attractive to mosquitoes, says a study.
Soapy fragrances can make you a target for mosquitoes as, according to the researchers, they supplement sugar intake with plant nectar when not feeding on blood.
Fragrance is something that people gravitate towards to alter their smell, with fruity and floral being the famous scents.
Virginia Tech researchers in the College of Agriculture and Life Sciences published a study in the journal iScience that found that certain soaps could make people more or less attractive to mosquitoes.
Lead researcher of the study Clement Vinauger said that just by changing soap scents, someone who already attracts mosquitoes at a high-than-average rate could further amplify or decrease that attraction.
The team studied the connection between soap and mosquito attractiveness with the help of four volunteers. First, they studied the unique scent profile of each individual, unwashed and washed with each Dial, Dove, Native and Simple Truth soaps.
It was found that over 60 per cent of what is smelled after washing comes from soap rather than natural body odours.
“The other aspect is that it’s not simply adding stuff to our body odour, but it’s also replacing some chemicals while eliminating others that are washed away,” Clement Vinauger said.
“So we think there is a lot of chemical interaction between our natural chemicals and soap chemicals,” he added.
Some soaps increase host attractiveness for mosquitoes while others reduce it, the study stated.
To find nutrients, mosquitoes use volatile organic compounds (VOCs) emitted by plants and animal hosts.
To test the interactions between smells, the researchers released mosquitoes in a meshed cage that had two cups containing odour extracts and gave them a choice – unwashed scents gathered from the individuals or their washed scents.
Tests were repeated for the various combinations of scents. In terms of fragrance preferences, three of the four soaps increased mosquito attractiveness while one decreased.
COCONUT-SCENTED SOAP REDUCED MOSQUITO ATTRACTIVENESS
All of the soaps had a fruity or flowery scent. The one that decreased attractiveness was the coconut scent.
As per the researchers, coconut-scented soap reduced mosquito attractiveness. The conclusion drawn from the study, as per the team, was that soap is only one part of the equation.
Deodorants, laundry detergents, and other scented products could also play a factor.
