Bird Mite
Scientific Name: Dermanyssus gallinae
Order & Family: Mesostigmata, Dermanyssidae
Size: 0.7 to 1.0 mm (unfed); up to 1.5 mm (engorged)

Natural Habitat
Bird nests, poultry coops, sometimes infest human dwellings after birds leave (e.g., from attics, chimneys).
Diet & Feeding
Blood of birds (primarily chickens and wild birds). They will bite humans if their primary hosts are unavailable.
Behavior Patterns
Nocturnal feeders, hiding in cracks and crevices during the day. They have a rapid life cycle (about 7 days from egg to adult) and can survive for several months without a blood meal. They are highly motile.
Risks & Benefits
Potential risks include irritating bites on humans (causing itching, skin irritation similar to mosquito bites), and they can transmit diseases among birds, leading to stress, anemia, and reduced egg production in poultry. No known benefits to humans or ecosystems in the context of infestation.
