Well at one time it was a deer tick and only Borrelia Burgdorferi. However, you can get Lyme from mosquitoes, fleas, horse and sand flies, lice, mites, spiders, bedbugs, and I have a microbiologist studying bugs for me. Also the roach, an omnivore, carries it and they do bite and chiggers have come up positive. Also, many other forms of ticks including the lone star and brown dog tick.
