A study from 2011 first described how individuals who are very attractive to mosquitos (An. gambiae s.s.) have a low biodiversity of the skin microbiome.
In addition, it identified specific bacteria genera associated with attractiveness to mosquitos.
This finding is elaborated on in a 2017 work, where different types of mosquito were found to be more attracted to people who have a skin microbiome that contains a certain amount of specific species of microbe.
The finding, backed up by a study in 2022, describes how microbes on our skin produce volatile compounds that determine whether or not a mosquito decides to bite a human.
To conclude, increasing the biodiversity of the skin microbiome could help protect you against being bitten by mosquitos. This finding is interesting because a low biodiversity on the skin has been associated with a huge array of other skin problems.
