Bird Mite

Typically found in bird nests (sparrows, starlings, pigeons) or poultry houses; they may enter homes through windows or vents if a nest is nearby.

They are hematophagous, meaning they feed on the blood of birds, though they will bite humans and other mammals if their primary avian host is unavailable.

They are most active at night. If a bird nest is abandoned or removed, the mites migrate in large numbers looking for a new host, often appearing as tiny moving specks on walls, ceilings, or bedding.

While they cannot survive or reproduce on human blood alone, their bites cause intense itching, irritation, and sometimes dermatitis in humans. They do not transmit diseases to humans but can be a major nuisance. Benefits are negligible; they are considered a pest.
