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.
