Bird Mite
Dermanyssus gallinae
- Order & Family
- Order Mesostigmata, Family Dermanyssidae
- Size
- 0.7 mm to 1 mm (extremely small, often appearing as tiny moving specks)
Natural Habitat
Typically found in bird nests (pigeons, starlings, sparrows) or in homes near nesting sites, often entering through windows or vents.
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 most active at night. When bird hosts leave the nest (fledging), the mites disperse in search of a new blood source. They cannot complete their life cycle on human blood but can survive for several weeks without a host.
Risks & Benefits
They cause intense itching, skin irritation, and dermatitis in humans. While they do not transmit diseases to humans, they are significant pests in the poultry industry and can cause severe anemia or death in young birds.
