Why Do you Hear a Buzzing Noise Whenever a Mosquito Passes You?

That Annoying Mosquito Sounds have got to Stop

A mosquito buzzing in your ear on a warm summer night may be the most irritating sound on earth. Summer just wouldn’t be summer without the buzz and tickle of a mosquito in the evening for most Floridians. However, does that have to be the case?

What causes mosquitoes to buzz in your ear?

Does it seem like mosquitoes like to buzz around your ears? Basically, they’re attracted to heat and carbon dioxide, both of which we are constantly exhaling. Every time you exhale, you release a plume of carbon dioxide that potential mosquitoes can smell out and follow. Mosquitoes have sensors around their mouths that allow them to detect carbon dioxide, and this allows them to find you from a distance of up to 50 meters.

It makes sense that some people tend to get targeted more since they naturally produce more carbon dioxide. Those who are larger or heavier exhale more gases, which makes them more likely to be on a mosquito’s radar. Additionally, if you’ve been running and are feeling a little short of breath, you might be surprised at all the mosquitoes trying to keep up with you. 

Pregnant women also face greater risks. A study found that pregnant women exhale approximately 20% more carbon dioxide than non-pregnant women, so pregnant women should take extra precautions outside. 

What Is the Reason for That Sound?

Is it because they’re bloodthirsty sadists that ruin our summers and keep us awake all night long? I wouldn’t say that. It turns out that the buzzing noise you hear is caused by the flapping motion of the mosquito’s wings, which can actually beat up to 1,000 times per second. Their buzzing sound is believed to change pitch as they increase or decrease the frequency of their flapping, especially when they pursue a mate.

A mosquito’s legendary whine is created by both male and female mosquitoes, though females produce a higher-pitched chirp. It’s possible to hear a male mosquito buzz, but most humans never hear one because they feed off of nectar and plants and leave us alone.
