Back in the day I worked for the USGS and I site I had to check was an old dump that had been reclaimed. First time I hiked in with shorts and a t shirt on and realized to late that the area was swarming with ticks. I had 100+ on me by the time I got back to the truck. Every other time I went in with pheasant pants tucked into boots and long sleeves all doused in a mixture of tick sprays. I could watch them try and crawl up and fall off my pants. Still would get a few but it prevented 99%. Ticks are nasty, I would feel ghost ticks for days after. Thankfully not an issue in ID, only found one.
