If a bird falls out of its nest and dies or if a nest is abandoned, bird mites may search for other hosts. These mites may enter homes when nests are located on or in buildings, and may bite humans as they search for new hosts. However, bird mites cannot reproduce on human blood. Bird mites are most active during the summer months and can survive for about two weeks without a bird blood meal. Northern fowl mites and chicken mites will die if they do not have access to a bird blood meal.
Bird mites, which are small arthropods, are usually less than one millimeter in length. Although they are small, they can be easily spotted with the naked eye due to their nearly constant movement. In fact, some people describe their appearance as resembling walking flakes of pepper. Despite their tiny size, bird mites can be a nuisance as they can bite humans and cause skin irritation. It is important to take preventive measures to avoid an infestation of bird mites in your home.
