Why do moquitos suck so bad?

Today I am interviewing my allergist for my Garden Journeys segments on TWC news. It was the cameraman's idea after he was bitten a bunch of times earlier this summer. I'm planning t ask her what makes mosquito bites itch and how to care for your bites for a speedy recovery. I'm glad to be doing another indoor shoot so I won't be so sweaty and squinty on camera! I'll post the segment after it airs. If you have Time Warner Cable in Austin or San Antonio look for the segment this Saturday at :46 past the hour and on Weds at :46 past the hour every hour.
