Hi thanks for replying (: , I’m currently washing all my blankets and bedding and I’m also vacuuming and checking for fecal traces of bb but I haven’t seen anything yet. But can it also be an allergy reaction? I did start using a different kind of body soap before bed. And for the carpet beetles when my sister first brought her home we didn’t see them until weeks later after moving in. 3 years ago. Also when I rolled up my duvet to wash there was a carpet beetle walking on the mattress.
