Ann T. MacIntyre, DO, a Miami-based osteopathic physician specializing in infectious diseases, notes that research has found some people are more prone to mosquito bites.
MacIntyre says. In a study , scientists found that having large amounts of a few types of bacteria made skin more appealing to mosquitoes. Surprisingly, though, having lots of bacteria but spread among a greater diversity of different species of bacteria seemed to make skin less attractive. This also might be why mosquitoes are especially prone to biting our ankles and feet—they naturally have more robust bacteria colonies.
Just a single ounce bottle of beer can make you more attractive to the insects, one study found. But even though researchers had suspected this was because drinking increases the amount of ethanol excreted in sweat, or because it increases body temperature, neither of these factors were found to correlate with mosquito landings, making their affinity for drinkers something of a mystery. In several different studies , pregnant women have been found to attract roughly twice as many mosquito bites as others, likely a result of the unfortunate confluence of two factors: They exhale about 21 percent more carbon dioxide and are on average about 1.
They fly upstream using the shift in concentration of CO2 along this stream to orient themselves. Subsequently people that emit higher levels of CO2 are more attractive from a distance such as those that are exercising or others that have a higher resting metabolism, such as larger individuals.
In general, this means men are more likely to attract mozzies than women, children are less susceptible than adults, and full-figured individuals including pregnant women are more attractive than their slimmer counterparts. One study found that the mosquitoes responsible for spreading malaria are attracted to Limburger cheese, a stinky European variety.
This last point underlines the fact that your appeal to mosquitoes can be transient — people can lose weight, pregnant women have their babies, and people trade the treadmill in for watching TV on the couch. The detection of CO2 is not just important for orientation; it has been shown that its presence is necessary to trigger the other senses for refining the search.
As mozzies get closer, thermal detectors that can clock temperature differences of around 2. Anything over 40 degrees is getting too hot, but normal human body temperature is just right. The final stage is related to body odour which is where it starts to get complex — but super cool.
It has been known for some time that mosquitoes are attracted to certain scents and that different species of mosquitoes vary in their preferences.
For example, one study found that the mosquitoes responsible for spreading malaria are attracted to Limburger cheese, a stinky European variety.
