Why Do Mosquitos Bite?

• Only female mosquitoes bite. They’ve evolved a proboscis, a long, tubular mouth that can puncture the skin and suck blood. They seek to feed on blood to get the nutrients required to produce eggs. A male mosquito’s primary role is reproduction.

What are Mosquitos Attracted to?

• Mosquitoes are attracted to moist areas to breed and produce eggs. That's why it’s veryimportant to prevent standing water in your yard and other areas around your home.

What Attracts Mosquitos to Humans

• Your blood: Female mosquitoes feed on blood in order to provide nutrients to their eggs.
• Your breath: Mosquitoes are attracted to the carbon dioxide we exhale, both the scent and the amount. Every time we exhale, we release chemicals that combine with CO2 to form our own unique carbon dioxide mix. This combination of scents is what triggers mosquitoes that there is a human target nearby. The more CO2 we emit, the easier we are to recognize. 
• Body Odor: Bacteria combined with sweat generates the scent we call, body odor. Without the bacteria, our sweat would be odorless; with the bacteria, our sweat is one of the more attractive scents for mosquitoes.
• There are measures you can take like washing regularly to reduce body odor. However, be careful of fragrant scents that can also draw mosquitoes.
• Blood Type and Other Factors: Depending on the type of blood you have, you secrete different scents. Studies have shown that mosquitoes are most attracted to Type O blood and least attracted to Type A. Another factor that affects it is your metabolism. Scientists have established that an individual’s genetic make-up can account for 85 percent of the various factors that make them a "mosquito magnet".
