Blood louse on Dragon

Question
For the past couple of days I have been pulling some tiny parasite like bugs out of my male bearded dragon's ears he's been with me for 5 years couple of days a go I've seen him just sit there all uncomfortable look on him with his eyes closed.  I looked at him to see what was wrong then I saw something in his ears moving I pulled out three at first in his right ear then I crushed them I thought they were mites being brown I went to get mite medicine for reptiles the next day then I saw more in his ear I pulled them out again then I looked closely they didn't look like mites they were brown with the center of the abdomen a  darker color they had six legs they looked like louse but they were drinking my poor bearded dragon's blood because when I pooped them blood came out.  They looked like this http://flushrush.com/insects-will-be-happy-to-suck-your-blood/  on the bottom of the page the one that says louse.  How can louse be eating my dragon internet says they eat mammals and birds.  Then again I work at a pet shop show I could have carried them home.  But anyways they are not mites as mites are arachnids and eight legs these had six legs also I found a two whole groups cluster in two corners of his tank I took them out and kept them alive maybe I should bring them to a vet to find a way to dipose of them.  How did I get them the first place?  How do I get rid of them?  Can they transfer disease?  What can I do I have never heard of louse drinking reptile blood?

Thank you for your time.

Hi Thomas,
  I will admit that in all my time, I have not heard of reptile lice.  I wonder where you are located and wonder if they could be some other kind of larvae.  I seriously think you should be getting to a good reptile vet, this may be a bird louse, and I would have him treated definitively since it is now effecting his overall health.  Go ASAP.
