Goodbye mosquitoes: a recent study reveals the scent that keeps them away

Mosquitoes are attracted to scent because they feed on sweet-smelling flowers. For this reason, washing with perfumed products attracts these insects. However, it must be kept in mind that a person’s scent is the result of a combination of hundreds of chemicals, some of which are produced by the body, while others are produced by bacteria that inhabit our skin. And each of these combinations is unique to each individual.

Why are mosquitoes attracted to scent?

The key to the problem

The scientists thus identified the key to the problem: the combination of scents between the human body and the products used. The lead author of the study, Clement Vinauger, an assistant professor of biochemistry at Virginia Tech who studies the molecular genetics of how mosquitoes choose their prey, said: ‘What really matters is how the chemicals in the soap combine with the chemicals in the individual person.

Scented soaps

Specifically, four types of scented products that are applied to the skin were examined: the product brands used for the experiment were Dial, Dove, Native and Simple Truth. The products chosen had different chemical compositions and fragrances.

The results of the experiment

The results of the experiment indicate that citrus fragrances, generally known to repel mosquitoes, instead seemed to attract them. As for the scents that are supposed to repel them, the results were generally weak and variable for all but one of the chemical scents tested: coconut. However, the scientists are not sure whether it is the coconut perfume that repels mosquitoes or whether it enhances one of the chemicals naturally present on human skin that is a repellent; moreover, they stated that they are not sure whether this applies to all naturally occurring mosquito species. In any case, the coconut-scented product was the one with the most satisfactory results.
