Bird mites can bite humans but are unable to survive on human blood. They require a blood meal from a living bird host, and they die within three weeks without this food.
Bird mites are small eight-legged arthropods that are barely visible to the human eye. They are oval-shaped and are sparsely covered with short hairs. Bird mites may crawl on human skin after coming into contact, usually after an infected bird has found a way into a home through broken tiles or unprotected eaves. While bird mites only live for about a week, they can reproduce rapidly and create large populations.
