Ive always heard that anything you put on them to back them out is dangerous, as it causes them to 'puke' their stomach contents out into you.If you are unfortunate and still find an attached tick, try Shooters Choice MC #7 Bore Cleaner. A small amount on a patch rubbed on the pest and they release and die.
usually i can feel the difference between a tick, or an ant. ticks crawl different. ever so often a tick gets by. like a deer tick or a seed tick.Ive always just scraped em out with a good sharp pocket knife...but bobby pins work pretty good too
