I've been a mosquito magnet since birth. On group hikes, camping trips, or family backyard gatherings, I wind up with dozens of bug bites when everyone else gets two or three. Last summer I counted 31 mosquito bites on just my legs after a weekend of camping in Acadia National Park. The itching was so bad that I put ice cubes in my leggings in hopes of numbing the bites enough so I could sleep. It didn’t work: they stayed itchy and then I just had wet pants.
