Do Mosquitoes Die After They Bite You? 

Mosquitoes, the tiny buzzing nuisances that infiltrate our peaceful summer evenings, have long been the subject of several misconceptions. One of which is the question, “Do mosquitoes die after they bite you?” We’re going to answer this question and more pertaining to what happens after a mosquito bites you.


Mosquito Behavior as it Relates to Biting Humans & Other Mammals

It’s important to note first and foremost that only female mosquitoes bite. They do this in order to obtain the protein found in blood, which they need to produce eggs.

Male mosquitoes, on the other hand, feed solely on plant nectar. Female mosquitoes are guided by their incredible ability to sense carbon dioxide (CO2) and heat, which is how they find their mammalian targets.

Once the female mosquito finds a suitable host, she uses her specially adapted mouthparts, collectively known as a proboscis, to pierce the skin and locate a blood vessel. She injects saliva, which contains anticoagulants to prevent the blood from clotting, allowing her to feed more easily.


Do Mosquitoes Die After They Bite You? 

The short answer is no, mosquitoes do not die after biting humans or other mammals. Female mosquitoes need a blood meal in order to reproduce. If they were to die after biting a host, it would disable their natural reproduction abilities. 

Mosquitoes will only die after biting if you kill them yourself or if your blood contains some type of pathogen or chemical lethal to them. 


What Happens After a Mosquito Bites You?

What Happens to Humans:

For humans, the interaction doesn’t end with a mosquito getting its meal. After a mosquito bites you, a bit of its saliva remains in your body, and it’s this foreign substance that triggers your immune system to respond. 

The typical response to a mosquito bite includes redness, swelling, and the hallmark itchy bump, which are signs that your body is reacting to the bite.

In some cases, mosquitoes can transmit pathogens like viruses and parasites, causing diseases such as malaria, dengue, Zika, and West Nile virus.

What Happens to Mosquitoes:

As for the mosquito, after obtaining her blood meal, she will rest for a couple of days and digest the blood, using the proteins to develop her eggs. Following this resting period, the mosquito is ready to lay her eggs and will start seeking out a new blood meal, repeating the process.

This is why mosquitoes do not die immediately after biting; in fact, a single female mosquito can bite multiple times in her lifespan, which can range from two weeks to a month, depending on species and conditions.
