- 0.5 mm to 1 mm (extremely small, barely visible to the naked eye)
Natural Habitat
Commonly found in bird nests, poultry houses, and inside homes near bird nesting sites like eaves or chimneys.
Diet & Feeding
Nymphs and adults feed on the blood of various bird species; they may bite humans if their bird hosts are unavailable.
Behavior Patterns
They are highly active crawlers that leave nests once young birds fledge. They are semi-transparent when hungry and turn reddish-brown after feeding.
Risks & Benefits
Can cause severe itching and skin irritation (dermatitis) in humans, though they cannot survive or reproduce on human blood alone. They are significant pests in the poultry industry.
