You are sitting on the patio with your family and everyone else seems fine. Your spouse is not even swatting. The kids are running around without a care. And you are sitting there getting absolutely destroyed by mosquitoes while nobody next to you seems to be attracting a single one. It happens every time. You are convinced mosquitoes have a personal vendetta against you and at this point you are not entirely wrong.
Mosquitoes do prefer some people over others and the reasons are real, documented and have nothing to do with how sweet your blood is. That is a myth. Here is what is actually going on.
Your Body Chemistry Is the Main Factor
Mosquitoes locate their targets primarily through smell. They detect carbon dioxide from your breath, heat from your body and a range of chemical compounds produced by your skin. The combination of those signals is what draws them in and some people produce a significantly more attractive chemical profile than others.
Lactic acid is one of the biggest attractants. Your body produces lactic acid during physical activity and it is also present in sweat. People who produce more lactic acid through their skin attract more mosquitoes. If you tend to run warm, sweat more than average or have just been physically active you are producing more of the chemical signals mosquitoes are following.
Certain skin bacteria also make a difference. The microbiome on your skin breaks down sweat and other compounds into volatile chemicals that mosquitoes can detect from a significant distance. People with higher concentrations of certain bacteria on their skin surface produce a more attractive scent profile for mosquitoes regardless of how clean they are. This is largely genetic and not something you can meaningfully change.
Blood Type Actually Does Matter
The sweet blood myth is wrong but blood type does play a role. Research has shown that people with Type O blood are bitten roughly twice as often as people with Type A blood with Type B falling somewhere in between. About 85 percent of people secrete chemicals through their skin that signal their blood type and mosquitoes can detect those secretions. If you have Type O blood and you are a secretor you are genuinely more attractive to mosquitoes than most of the people around you.
Carbon Dioxide Output Makes a Difference
Mosquitoes track carbon dioxide plumes to find their targets from distances of up to 50 meters. People who exhale more carbon dioxide attract more mosquitoes. Larger people exhale more CO2 than smaller people simply because of body mass. Pregnant women exhale roughly 21 percent more carbon dioxide than non pregnant women which is one of the documented reasons pregnant women get bitten more frequently. People who have just exercised are exhaling more CO2 and are more attractive as a result.
If you are consistently the most bitten person in your group and you tend to be larger, run warmer or breathe harder than the people around you those factors are likely contributing to the disparity you are noticing.
Alcohol Consumption Increases Mosquito Attraction
Studies have shown that people who have consumed alcohol are more attractive to mosquitoes than people who have not. The exact mechanism is not fully understood but it appears to be related to changes in skin temperature and the compounds released through the skin after drinking. If you are noticing that the evenings you get eaten alive correlate with evenings on the patio with a drink in hand that is not a coincidence.
Dark Clothing Makes You a Better Target
Mosquitoes use vision to locate targets at close range after tracking them through scent and CO2 at longer distances. Dark colors absorb heat and create more visual contrast against the sky and background which makes you easier for a mosquito to locate visually once it is in your vicinity. People wearing dark blue, black or red clothing are bitten more frequently than people wearing white or light colors in the same environment. If you tend to wear dark clothing while the people around you are in lighter colors that is contributing to the disparity.
Why Reducing the Mosquito Population in Your Yard Still Matters
Even if you are genetically predisposed to attracting more mosquitoes than the people around you the number of bites you get is directly proportional to how many mosquitoes are in your yard. Reducing the mosquito population through professional barrier treatment does not change your attractiveness to mosquitoes. It reduces the number of mosquitoes available to find you.
A yard with a dramatically reduced mosquito population from professional treatment is still going to send more of those remaining mosquitoes toward you than toward your spouse. But dramatically fewer total mosquitoes means dramatically fewer bites even accounting for your higher personal attractiveness. Our mosquito control service reduces the population in your yard so the mosquitoes that are genetically drawn to you have a lot less company when they show up. Call us for a free estimate and let us make your yard a place you can actually sit in without becoming the evening meal.
