Yeah, I've just seen people have some bad skin reactions too it (the inorganic kind, not the organic stuff) . But like I said, maybe the stuff we used was more concentrated than the kind they use for AG. I'm certainly neither a farmer nor a chemist.
When I was in forestry there were several people on the crew that had to use alternative treatments because they would get crazy rashes from clothes that had been treated. I always just tried to be vigilant cause I don't like using chemicals of any kind on myself but those days working in the dense thickets in Central MA made me cave sometimes.... you'd look down sometimes and have dozens of the suckers climbing up your pants. I've been bit more times than I can recall, it's amazing I've never contracted anything from it.
Anyways, I just remembered we're in Herks journal.... sorry for the hijack man. Whatever you do hope your able to rid yourself of those little buggers.
