Natural Habitat

Found globally in human dwellings, particularly in cracks and crevices near sleeping areas such as mattresses, bed frames, and headboards.

Diet & Feeding

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

Behavior Patterns

They are primarily nocturnal and elusive, emerging from hiding at night to feed. They undergo incomplete metamorphosis (egg, nymph, adult) and require blood meals to advance through life stages.

Risks & Benefits

They are significant structural pests that cause psychological distress, sleep deprivation, and itchy allergic reactions from bites. While not known to transmit diseases to humans, infestations are difficult and expensive to eradicate.
