Diet & Feeding

Obligate hematophagous (blood-feeders), primarily targeting humans but may also feed on other warm-blooded animals.

Behavior Patterns

Nocturnal and elusive; they use heat and carbon dioxide to locate hosts, feed for 3-10 minutes, and then hide to digest. They reproduce via traumatic insemination and have a hemimetabolous life cycle.

Risks & Benefits

Risks include itchy skin rashes, psychological distress, and allergic reactions. While not known to transmit diseases, they are significant domestic pests that are difficult and expensive to eradicate.
