When (if ever) does chigger season end? Anyone have any old Piney remedies for killing them when you see them on your legs or how to stop the itch once they've dug in?

I scratch each bite until it bleeds. Usually works very well for me......like they don't itch again until the scab drys out. A little morbid? Perhaps, but I'm telling you it works. Was taught this trick by an old piney.
I agree, though, that this year they've been especially ferocious since there's so many of 'em. Needless to say, I've bled a lot lately.
I try to stay out of the woods until October 15 in order to avoid chiggers. Either this works or I have been extremely lucky for a long time.
The 15th is just two days away, no frost yet, weather is not so different from what we had a month ago. I try to avoid places like tall grass and heavy underbrush until we have a nice solid freeze.
