Most of the time, the bites don’t hurt. You may sleep right through them. The bugs might hit anywhere on the body, including the face, head, arms, and feet. Kissing bugs are so named because they like to bite around the mouth or eyes.
You’ll often see 2-15 bite marks in one area and maybe redness and swelling. It might be hard to tell them apart from other bug bites, minor skin irritations, or infections.
