Over the past 2-3 months I have been getting itchy bumps. They look like bug bites but I am not sure. The first ones appeared after sleeping so I brought in the experts to check for bed bugs and they found no sign of them and suggested it could have been a spider. Few weeks later, I get bit again--in about the same spot! (lower back above waste band). Now I was thinking I might have mites since the place I was living at at the time had mice. I have since moved and just got 3 more bites (seemingly all at once) during the evening sitting on my brand new couch. So I moved, got new furniture, but seem to have taken something mysterious with me. I can't see what is biting me (we have had exterminators look, we looked ourselves for bed bugs at 3 am with flashlights and saw nothing at all that would suggest the little critters) Does anyone have any suggestions?
