Bird Mite
Ornithonyssus sylviarum
- Order & Family
- Order: Mesostigmata, Family: Macronyssidae
- Size
- 0.5 to 1.0 mm (hardly visible to the naked eye, appearing like moving specs of dust)
Natural Habitat
Typically found on domestic and wild birds and their nests; may migrate into homes when bird hosts leave the nest.
Diet & Feeding
Obligate blood-feeders; they primarily feed on the blood of birds but will bite humans and other mammals if their primary host is unavailable.
Behavior Patterns
They are highly active, semi-permanent parasites that spend most of their life cycle on the host. They can survive for several weeks without a meal in search of a new host.
Risks & Benefits
They do not transmit diseases to humans but their bites cause intense itching, skin irritation, and dermatitis. They provide no ecosystem benefits to humans and are considered domestic pests.
