Hey Lisa,
One of my husband's most memorable Army experiences was a training exercise in Arkansas. He described the ticks perched at the ends of plant stalks, waving their creepy little legs around, waiting for you to walk by and give them a ride and a meal. After the first day, he had ten ticks. Some experienced tick-fighters told him to eat the match heads from his MRE packet. He did, and when the sulfur had permeated his system, the ticks let go on their own. Of course, I had to throw away all the t-shirts he wore then, because the sulfur smell would not come out in the wash.
Chiggers, he tells me, will die if you paint the red points of entry with nail polish. Gag me with a rattlesnake.
