arrgh!! Now my head is itching!!!

We ( preschool) went on a fieldtrip to a park, and hiked through the woods a bit. Ticks are thick now. We checked after we got done, and found few on some kids. ( not attached yet or anything). Anyway, I felt like I had them crawling on me all day! I kept shaking out my hair! And sure enough, I did find one crawling on my shirt!!!
I have never experienced nits ( lice, we call them here). KNOCK ON WOOD!!! I hope you are washing EVERYTHING so you don't get a recurrence. Good luck Helena!
