We all know that female mosquitoes actually bite as male mosquitoes stay in plants and moist areas.
But a real fact is that “MOSQUITOES NEVER BITES”. Yes! Mosquitoes never bites it just pierces the upper layer of our epidermis in skin and then searches for a blood vessel. Once it finds out the blood vessels, the mosquito releases saliva in the wound.
Now our immune system gets an alert and realizes that something is going on. Immune system then produces Histamine a chemical compound to combat the foreign substance and a swell is automatically produces in the vessels.
When blood vessels become swollen, our nerve ends gets irritated and it produces a itchy effect.
