OMG!!!!!Just the thought of these MISERABLE bugs make me cringe. We go every July and I have never been bit then. BUT, we went this past April also, and let me tell you, I woke up one morning to 37, yes thats right 37 welts on my legs. I counted each and every one of them after I scratched and scratched and scratched them. I did feel them ATTACK me just a little, but nothing to even think about, until the next morning when I got out of bed and my legs touched the edge of the bed getting out of it. That little move made for the WORST itch I ever ever had in my life. Just sitting in the car made them itch, each pot hole we passed set the itch off, I think just looking at them made them itch more. It almost ruined my trip. I looked like I had some horrible disease. We went to the drug store and bought everything they had for bug bites, itches, and rashes. I spent a small fortune. After a good 4-5 days the itch went away, but I still had the marks for almost 2 weeks later. PLEASE BRING BUG SPRAY. And there pretty selective with who they bite. I did everything the same as my dh and my dd, yet, I was the only one attacked by them. We just got back from our usual July trip and they didn't come near me. I don't know if there seasonal or not, but if I ever go in April again, I'll be the one you see dripping in bug spray.
