Mosquito Bite (Itching): What Causes It, What’s Good for It, Ways to Prevent It

Mosquitoes are small, short-lived, delicate animals belonging to the winged insect group, easily recognized by their thin and long legs. Mosquitoes, which usually enter our lives at summer nights, are known for the itchy bumps they leave on the skin after biting. The itchy bumps that appear prominently are allergic reactions that develop as a result of a chemical that mosquitoes use to suck blood. Flies that feed by sucking blood are generally known as female mosquitoes. Female mosquitoes need the protein found in human or animal blood to reproduce. Male mosquitoes feed mostly on flower and plant sap. Mosquito bites disappear within twenty-four hours on average and do not cause serious problems. However, it should be monitored for allergic reactions. In addition, serious diseases such as malaria, West Nile virus, equivalent disease, elephantiasis, yellow fever, and Zika virus can be seen in endemic areas.

What Causes Mosquito Bite Itching?

Female mosquitoes need to lay eggs in the blood for reproduction. They usually suck blood from amphibians, reptiles, birds, animals and humans. Some mosquito species do not need to suck blood to lay eggs. Because mosquitoes have a thin proboscis, they can easily suck blood through the skin. To prevent clotting in the sucked blood, mosquitoes release saliva into the vein. Saliva released into the vein stimulates the nerve endings in the tissue and causes pain and itching in the bitten area. A mosquito bite causes a swelling of 2-10 mm in size. At the same time, the salivary fluid left in the veins by mosquitoes is the main factor in the transmission of some diseases. As the amount of blood absorbed increases, a decrease in the itching effect is observed.

Mosquito bite itching heals faster thanks to special gels applied to the bitten area. Do not apply alcohol-containing perfume, cologne, etc. to the itching area. The use of products causes skin irritation and paves the way for stain formation. Additionally, when the area bitten by mosquitoes is scratched, it may cause skin redness and bleeding. In such a case, the skin bleeds open, which paves the way for infection.
