I guess we're quite fortunate for at least one thing up here in Canada,very low numbers of Lyme disease. I've had deer tics on me and my hounds ,I removed them with no ill effect
Once when I was in the thousand islands I got a tic on my neck, not a deer tic this sucker was black with a white diamond in the middle of it's back.I was told these were more likely to be carries of Lyme disease.
