What Happens After You Get A Mosquito Bite?


You got him!

…but you were too late.

This tiny terror had already sucked your blood and left its mark before you even noticed it was there. So now what?

This is what actually happens to your body when you get bit by a mosquito.

During the bite

Mosquitoes are stealthy creatures. I doubt anyone would disagree with that from the number of “where did those come from” mosquito bites people receive in the Summertime. If you think about it, mosquitoes are only 3mm-6mm long and weigh about 5mg. It’s hard to believe that such small insects can create such large problems. When a mosquito lands on you they immediately begin to look for a thin layer of skin, preferably close to a blood vessel. Once they find the perfect spot, they inject their long probe-like tongue into your skin and pump a numbing saliva into your body.

After the bite

Once the mosquitoes saliva has entered your body it’s game over. Your body detects this unwanted and foreign content and rushes to the scene. Lymphocytes, a type of white blood cell used to attack any unwanted bacteria, viruses, or toxins that enter your body, come to the rescue to annihilate the mosquito’s saliva. Although these cells are helpful, the mixture of the saliva and the white blood cells are what cause the itchy sensation. DON’T ITCH IT. It only makes it worse (easier said than done, we know).

Fun Fact: A mosquito could be on your body for 4+ minutes if undetected. As mosquitoes drink, red blood cells rush to their probe-like tongues quickly. Sometimes mosquitoes can suck the blood so hard that they will explode.

Unfortunately, the aftermath of mosquito bites can hang out for a few days. Some people only have symptoms for 24 hours, some will have them up to 2 weeks. It just depends on how your body reacts to the saliva. The main symptoms include itchiness and swelling.

What if the mosquito has the malaria parasite?

When a mosquito injects this parasite into its host’s skin, the parasite attacks the liver cells. Once these get to the liver, they burst open and travel throughout the body. They attach to red blood cells, kill those cells, and then move onto other red blood cells and do the same. Mosquito parasites that cause illnesses like malaria, dengue, chikungunya, yellow fever, and Zika, are extremely vicious and persistent. Those initial white blood cells can’t handle the push from these parasites, which causes the spread of the diseases throughout a persons body.


As you’re out and about this Summer, utilizing mosquito sprays and repellents are key. Those who reside in areas where mosquito-borne illnesses are prominent should be using insecticide covered bed nets, and other repellents available to them. Research is being done every day to help prevent the spread of mosquito-borne diseases. DynaTrap hopes to make a greater impact in the countries that bug bites cause much more than an itchy red bump. DynaTrap is a mosquito relief and insect repellent you can trust.
