for what it's worth.......
I sprayed "the spray" heavy the last couple times out. No bug bites at all, but I wandered into poison ivy.......not terrible, but enough to get my attention. I got it on my wrist and neck.. This was just a small "touch".......... I got it much worse when I was in the military many years ago. its' all good.........I was walking the woodline...and learning for the winter, and eating spiders and apparently rubbing poison ivy.
