Have you done a bird mite confirmation via vetdna.com?
We have been hearing about our readers using them with some success to learn exactly what type of mites they have. From their website:
Since 1992 Research Associates Laboratory has been providing state of the art molecular diagnostics to veterinarians, zoos, universities, restaurants, hotels, and the pet and pest industries. We are the nation’s oldest and most experienced veterinary molecular diagnostic laboratory.
We are the only diagnostic laboratory offering affordable next day results 5 days per week.
Their “what’s biting me” test kits are inexpensive ($18) and tests for bird mites and a host of other pests. Here is a link. If you have a review of their services you would like to share with us (and our site) please email us at info@birdmites.org.
