Mosquito bites
itch because the glob of
saliva the mosquito sticks there to prevent
bleeding when it's done
feeding is
irritating to the
body. My personal theory is that
scratching the location will bring more
blood to the area, which will make the
nerves more sensitive, which will heighten the itching sensation. The best thing to do is think about something other than the bite until it goes away.
Only female mosquitos drink blood. Insert joke here.
Mosquito bite is also a slang term for a small breast or nipple.
