Diet & Feeding

Exclusively blood-feeders (hematophagous), primarily feeding on human blood, but will feed on other warm-blooded animals if humans are not available.

Behavior Patterns

Nocturnal, typically feeding at night while hosts are asleep. They are attracted to carbon dioxide and body heat. They crawl onto hosts, feed for a few minutes, then retreat to their hiding spots. They are gregarious and often found in clusters.

Risks & Benefits

Potential risks include itchy bites that can lead to skin irritation, allergic reactions, and secondary skin infections from scratching. They are not known to transmit diseases to humans. There are no known benefits to humans or the ecosystem.
