My daughter has gotten bed bug bites (pretty sure). She has sensitive skin so it’s pretty bad. I read that the bites can appear over the course of several days. She continues to show new bites. We washed all our clothes in hot water (according to the woman helping me) and dried them in dryer. I also emptied backpack and sprayed both of ours with permethrin. How do I know if these are new bites and we were unsuccessful in our washing or just the original? Dont know what to do. This didnt happen on my last Camino. I am giving Benadryl at night and have gotten her hydrocortisone. Any other help for the itch. She has them EVERYWHERE.
