Itchy little insects

I know that when a mosquito bites you, she injects you with some of her saliva, which keeps your blood from clotting so she can keep eating. This wakes up your immune system, which sends histamine to the site, causing the blood vessels to swell, which irritates the nerves causing them to itch (http://insects.about.com).

I don’t mind the bite itching when I’m bitten, but why does the darn thing have to keep itching for DAYS afterwards? By then I’ve forgotten I was bitten, feel the itch, reach up and scratch, and then remember that $&*%%^ little insect bit me and I’m itching all the worse.

Don’t ya love summer in Minnesota? If the heat doesn’t kill you, the insects will drive you insane.
