1 . Soap (肥皂) might seem like a reasonable way to avoid mosquito bites (蚊子叮) on the basis that if mosquitoes can’t smell you, they can’t bite you. However, a recent study has found that rather than protecting you, certain soaps might actually make you more attractive to mosquitoes.

In the study, conducted at Virginia Polytechnic Institute and State University, four volunteers were asked to wear a sleeve before and after washing with four different brands of soap. The researchers then watched female mosquitoes as only females feed on blood landing on the fabric sample to show their preference. They found that some people washing with some brands of soap, increased their attractiveness to mosquitoes, while washing with other brands of soap tended to repel (驱除) mosquitoes. The repellent effect of some soap may be due to its coconut scent, as coconut oil is known to act as a natural mosquito repellent. The reason behind this attraction is believed to be related to mosquitoes’ sugar intake. When mosquitoes are not feeding on blood, they add their diet with plant juice or sweet water from flowers, “The fact we are taking those flowery and fruity smells and putting them on our bodies means that now the same object smells like a flower and a person at the same time,” said Clément Vinauger, who led the study. It would be like waking up and smelling the smell of coffee and bread, very attractive.

Interestingly, the effects of the soap varied among people, possibly due to the interaction (相互作用) between the soap and each person’s unique body scent. “It’s remarkable that the same person that is extremely attractive to mosquitoes when he is unwashed, but he becomes even more attractive to mosquitoes with one soap, and then become repellent to mosquitoes with another soap,” said Vinauger. Further research is needed to better understand the interaction between different soap and body scents, as well as to develop more effective mosquito repellents.
