How Do Mosquitoes Smell Blood?

Unlike other creatures, mosquitoes don’t have a distinctive smell. They rely on volatile chemicals and other indicators to locate a target.

They use chemical signals to detect blood type, body heat, and carbon dioxide levels. Mosquitoes are also attracted to odors and bacteria.

One of the most important chemicals produced by the human body is lactic acid. This is an acidic substance that is produced by the skin when we are active. By washing with soap after exercise, we can reduce this acid.

Another indicator of human odor is the presence of bacteria on our bodies. Some of these bacteria, known as Brevibacterium linens, are found on our feet and are responsible for giving off the distinctive smell of humans.

The human body is capable of producing 500 different volatile chemical substances. These are released through the skin when we eat certain foods or sweat. The level of these compounds varies from person to person. The amount of each chemical is based on the DNA of the individual.

Although mosquitoes aren’t the best at smelling humans, they can recognize a host’s scent. They do this by using receptors in their legs.

The female mosquito is the only species to actually smell and taste blood. She uses this sense to find the next victim.
