How mosquitoes use taste and smell sensors to zero in on their victims

Before we list out mosquito attractants, let’s take a moment to discuss mosquito taste and smell sensors. Female mosquitoes have specialized taste receptors on their antennae that can detect trace amounts of carbon dioxide (CO2) released when we exhale. This helps them zero in on potential targets even from afar.

In addition to CO2, mosquitoes also rely on olfactory cues such as lactic acid, ammonia, or other volatile substances present on our skin surface which vary among individuals based on factors like genetics or diet. The combination of these unique smells makes each person more or less attractive to different mosquito species.

What makes mosquitoes attracted to humans

Let’s face it, mosquitoes are annoying, worse the illnesses infected mosquitoes spread through their bites in Denver and throughout Colorado can result in poor health. Understanding what attracts mosquitoes to humans can help minimize your risk of acquiring West Nile virus and other mosquito-borne illnesses. Here are some of the most common mosquito attractants:

  • Carbon Dioxide
    Mosquitoes are attracted to the carbon dioxide we exhale. When we breathe, we release carbon dioxide into the air, which mosquitoes can detect from over 150 feet away. The more carbon dioxide you produce, the more attractive you are to mosquitoes. An excellent example of this is pregnant women. During pregnancy, a woman’s respiratory system changes, and that results in an increase in the amount of air inhaled and the amount of carbon dioxide exhaled. As if pregnancy wasn’t hard enough in the summertime, right?
  • Body heat
    Mosquitoes are also attracted to body heat. When we're active or exercising, our bodies produce more heat, making us more attractive to mosquitoes. Additionally, mosquitoes are attracted to warm-blooded animals, so they can detect our body heat from a distance.
  • Chemicals in sweat
    Chemicals found in human sweat, such as lactic acid and ammonia, can also attract mosquitoes. These chemicals are produced by our bodies and can vary depending on factors such as diet, genetics, and overall health.
  • Blood type
    Research has shown that mosquitoes are more attracted to certain blood types than others. In fact, research shows that people with Type O blood are more likely to attract mosquitoes than those with Type A or B blood.
  • Size & movement
    Mosquitoes are also attracted to larger targets and people who move around a lot. This is because larger targets produce more carbon dioxide and heat, while movement can create air currents that carry the scent of chemicals in sweat.
  • Alcohol consumption
    Drinking alcohol can also make you more attractive to mosquitoes. When we drink, our bodies produce more heat, and our skin releases ethanol, which can be a mosquito attractant.

Tips for preventing mosquito bites

To minimize the chances of getting bitten by mosquitoes, we recommend the following tips:

  • Time outdoor activities wisely
    Avoid spending time outside when mosquitoes are more likely to bite. Here in Colorado, mosquito activity is high at dawn and dusk and peaks during the early evening hours.
  • Avoid alcohol consumption if you’re planning on spending time outdoors
    Since beer and alcohol consumption can make us more attractive targets for mosquitoes, it would be wise to limit your alcohol intake if you plan on being outside in areas where mosquitoes are likely to be active.
  • Wear protective clothing
    Opt for long-sleeved shirts, pants, and closed-toed shoes to reduce exposed skin where mosquitoes could potentially bite. Light-colored clothing is also less attractive to these insects.
  • Repair or replace torn window and door screens
    Keep mosquitoes out of your home and reduce the chances of being bit while you sleep by repairing or replacing screens that have rips and holes.

How to make your yard less attractive to mosquitoes

In addition to personal protection measures, making your yard less appealing to mosquitoes can help reduce their presence around your home and property. Consider implementing the following mosquito prevention tips:

  • Eliminate standing water
    Mosquitoes lay their eggs in stagnant water sources such as birdbaths, empty flower pots, and puddles; removing these breeding grounds will help control their population.
  • Maintain landscaping
    Keep grass trimmed short and bushes pruned back; this will eliminate hiding spots for adult mosquitoes while also reducing potential egg-laying sites.
