Two weeks ago, I had a few microscopic bird mite bites on my skin, whenever I handle my chickens. Now, I had 2-3 times more than what I had 2 weeks ago on my skin. I can confirm that it was microscopic bird mite bite, since my mom's dermatologist examined it, and confirmed it. My chickens have had mites before, but it was mites that can easily be seen with the naked eye. They are easily eradicated, by the chicken, if they had dust bathing and they can groom themselves and by applying soap and water when they take a bath. I know, that oral Ivermectin works on killing mites, but I don't know the right dosage for microscopic bird mites.Please provide an official link, and toxic dose and therapeutic dose for microscopic bird mites. I think they got it from the wild birds.
