Why do mosquito bites itch

Mosquito bites are very unpleasant and quite nasty and I am saying that from experience, because first they leave red bumps on our skin, and secondly these bumps – mosquito bites – itch like crazy no matter what you do. But why exactly mosquito and insect bites for that matter itch?

The truth is.. bug bites by themselves actually don’t itch at all, and a lot of the time you don’t even feel the moment an insect or a mosquito bites you. So why do you feel that the spot where a mosquito bit you itches?

The reason is related to the processes that happen under your skin once a mosquito has bitten you, which althea is quite fascinating also is quite unpleasant.

The mosquitoes belong to a suborder of elongated flies with thing antennae and aquatic larvae called nematocera. They have long and very thin proboscis or a type of sting (for all normal people) that they use to bite us and suck our blood to later use it to create eggs. It is very complicated in its build because even being that thin and small it consists of 6 different parts. Once the mosquito bites you, it has to be on your skin at least about 6 seconds to be able to suck your blood, because at this moment a very complicated process occurs – mosquito bites with one part of its proboscis and then releases another part, that looks like two tubes that they use to find blood vessels, suck our blood and to inject their saliva. This saliva is an anticoagulant, which means that mosquito saliva has the ability to stop your blood from clogging inside previously mentioned mosquito tubes, so that the mosquito can drink your blood as long as it is necessary for it. Unfortunately the saliva is also the main way how mosquitoes transmit diseases like malaria or West Nile Virus AND you are probably allergic to mosquito saliva, because almost all humans are. And when you are allergic to something your body produces histamine which is the protein that triggers inflammation, which in mosquito case looks like red bumps that itch. So the mosquitoes aren’t the ones that create the itching, their bites itch because we humans are allergic to mosquito saliva.

The good news is that with time the mosquito bites will itch less, because the more you are bitten by a mosquito the more your body comes accustomed to the mosquito saliva, producing less histamine, and the bites itch less. But still there is no real way to avoid the itchiness, only to lessen it with natural or not so natural remedies or avoid getting bitten by mosquitoes at all .
