Triatomine bugs, also known as kissing bugs, are blood-feeding insects found primarily in the Americas. They are known for their distinctive flattened bodies and long mouthparts, which they use to pierce the skin of their hosts, typically at night. These bugs are often associated with rural areas and can be found in cracks and crevices of homes. These insects are significant because they can transmit the parasite Trypanosoma cruzi, which causes Chagas disease. This disease can lead to serious health issues, including heart problems and digestive disorders. Preventing contact with triatomine bugs is essential for reducing the risk of infection.
