Natural Habitat

Diet & Feeding

Obligate hematophages, feeding exclusively on the blood of warm-blooded animals, primarily humans.

Behavior Patterns

Nocturnal parasites that emerge at night to feed. They undergo incomplete metamorphosis (egg, nymph, adult) and require a blood meal to progress through each growth stage.

Risks & Benefits

Significant urban pests that cause itchy welts, psychological distress, and allergic reactions. While not known to transmit diseases, infestations are difficult and expensive to eradicate.
