Bird lice or mites do not use humans for permanent hosts but they can certainly bite humans and become infestations, if they do have anything else to feed upon.
There was an article in Bird Watcher's Digest in a recent issue that documented an infestation that came into a home via a nest over an outside window. When the birds left, the insects came into the home. As they can multiply very fast, the lice literally took over a bedroom before the people took action with pesticides.
I do not use pesticides and have had very good success with diotomaceous earth against mites, fleas and lice. I buy it from a natural pet supply company on-line.
