Diet & Feeding

Obligate hematophages, meaning they feed exclusively on the blood of warm-blooded animals, primarily humans.

Behavior Patterns

Nocturnal insects that emerge from hiding at night to feed. They undergo incomplete metamorphosis (egg, nymph, adult). They are known for hitchhiking on luggage, clothing, and used furniture to move between locations.

Risks & Benefits
