Bird Mite

Bird nests, poultry houses, and occasionally indoor residences where birds nest nearby (e.g., eaves, vents, attics).

Blood of avian hosts (birds). If their bird host leaves, they may bite humans and other mammals, though they cannot survive or reproduce on human blood alone.

They are highly mobile and nocturnal feeders. When bird hosts fledge or die, mites migrate in large numbers to find new hosts, often entering homes through cracks or vents.

Risks: Can cause intense itching, irritation, and dermatitis in humans (mite bites). They do not transmit bird diseases to humans. Benefits: None to humans; they are parasitic pests.
