Bird Mite (or Tropical Bird Mite)

Commonly found in bird nests (sparrows, pigeons, starlings). When nests are abandoned, they migrate into homes and buildings.

Primarily the blood of birds; however, they will bite humans and other mammals if their primary host is unavailable.

They are highly active and exhibit rapid movement. They are most active at night or in high humidity. They cannot complete their life cycle on human blood but can survive indoors for several weeks.

Risks include intense itching, skin irritation, and dermatitis in humans. They do not transmit diseases to humans but can cause significant emotional distress and secondary skin infections from scratching. No ecological benefits to humans.
