Biting midges, also known as no-see-ums, are tiny flying insects that belong to the family Ceratopogonidae. They are often found in warm, humid environments, especially near water sources like lakes and marshes. Despite their small size, these pests can deliver painful bites, causing itchy welts on the skin. These insects are most active during dawn and dusk, making outdoor activities during these times a challenge. Biting midges are attracted to carbon dioxide and body heat, which is why they often swarm around people. To avoid bites, wearing protective clothing and using insect repellent can be helpful.
