The kissing bug (also known as the assassin bug) leaves a rash. The kissing bug is a type of blood-sucking insect found in the Americas. It is named for its habit of biting people on the face, especially around the mouth. The bite of the kissing bug can cause a rash, itching, swelling, and pain. The rash can last for several weeks.
