Had a bad problem with them when I was younger. My dad made me start bathing with Octagon soap after my hunting, fishing and blackberry picking outings. Don't know what it was about that soap, but if I bathed as soon as I got home, no chiggers or red bugs. Don't know if it would work for everyone, but it's definitely worth a try. It's like bathing with sandpaper, so maybe that and the smell is why it works.
