Kissing bugs, also known as triatomines, are a group of blood-sucking insects that can transmit the parasite Trypanosoma cruzi, which causes Chagas disease in humans and animals. These bugs are commonly found in the Americas, where they live in cracks and crevices of homes and other buildings. Kissing bugs are named for their habit of biting around the mouth and face of their victims while they sleep. Research on kissing bugs focuses on understanding their biology, behavior, distribution, and methods for controlling and preventing the spread of Chagas disease.
