Chiggers?

Here's something I learned from the Dick Williams guides to climbing the Gunks: If you want to keep chiggers off you sprinkle some sulfur powder in areas likely to be victimized (e.g. between sock and leg or between climbing harness and waist).

I'm yet to try this as I'm yet to be bothered by chiggers, but apparently this works like a charm. And it's a DEET-free solution.

I too came across this information Dave, although to be honest with you, I don't know if I want to smell like rotten eggs.

Powdered sulfur does not smell like rotten eggs. It's hydrogen sulfide which is rotten egg gas.

Cheers
