Kissing bugs are insects belonging to the family Reduviidae, specifically the subfamily Triatominae. They are known for their tendency to bite humans around the mouth and eyes while they sleep, which is how they got their nickname. These bugs are typically found in the Americas, especially in rural areas, and are attracted to warm-blooded animals. These insects are significant because they can transmit the parasite Trypanosoma cruzi, which causes Chagas disease. Symptoms of this disease can range from mild to severe, including fever and fatigue. Preventing kissing bug bites involves maintaining clean living environments and sealing cracks in homes to reduce their presence.
